-// Module Name     :  ALTERA_MF_MEMORY_INITIALIZATION
-//
-// Description     :  Common function to read intel-hex format data file with
-//                    extension .hex and creates the equivalent verilog format
-//                    data file with extension .ver.
-//
-// Limitation      :  Supports only record type '00'(data record), '01'(end of
-//                     file record) and '02'(extended segment address record).
-//
-// Results expected:  Creates the verilog format data file with extension .ver
-//                     and return the name of the file.

-// Module Name : MF_stratixii_pll
-//
-// Description : Behavioral model for StratixII pll.
-// 
-// Limitations : Does not support Spread Spectrum and Bandwidth.
-//
-// Outputs     : Up to 6 output clocks, each defined by its own set of
-//               parameters. Locked output (active high) indicates when the
-//               PLL locks. clkbad, clkloss and activeclock are used for
-//               clock switchover to indicate which input clock has gone
-//               bad, when the clock switchover initiates and which input
-//               clock is being used as the reference, respectively.
-//               scandataout is the data output of the serial scan chain.

-// START MODULE NAME -----------------------------------------------------------
-//
-// Module Name : ALTPLL
-//
-// Description : Phase-Locked Loop (PLL) behavioral model. Model supports basic
-//               PLL features such as clock division and multiplication,
-//               programmable duty cycle and phase shifts, various feedback modes
-//               and clock delays. Also supports real-time reconfiguration of
-//               PLL "parameters" and clock switchover between the 2 input
-//               reference clocks. Up to 10 clock outputs may be used.
-//
-// Limitations : Applicable to Stratix, Stratix-GX, Stratix II and Cyclone II device families only
-//               There is no support in the model for spread-spectrum feature
-//
-// Expected results : Up to 10 output clocks, each defined by its own set of
-//                    parameters. Locked output (active high) indicates when the
-//                    PLL locks. clkbad, clkloss and activeclock are used for
-//                    clock switchover to inidicate which input clock has gone
-//                    bad, when the clock switchover initiates and which input
-//                    clock is being used as the reference, respectively.
-//                    scandataout is the data output of the serial scan chain.

-//START_MODULE_NAME------------------------------------------------------------
-//
-// Module Name     :  altaccumulate
-//
-// Description     :  Parameterized accumulator megafunction. The accumulator
-// performs an add function or a subtract function based on the add_sub
-// parameter. The input data can be signed or unsigned.
-//
-// Limitation      : n/a
-//
-// Results expected:  result - The results of add or subtract operation. Output
-//                             port [width_out-1 .. 0] wide.
-//                    cout   - The cout port has a physical interpretation as 
-//                             the carry-out (borrow-in) of the MSB. The cout
-//                             port is most meaningful for detecting overflow
-//                             in unsigned operations. The cout port operates
-//                             in the same manner for signed and unsigned
-//                             operations.
-//                    overflow - Indicates the accumulator is overflow.

-// Module Name : HSSI_PLL

-// Description : This is the Phase Locked Loop (PLL) model used by altcdr_rx
-//               and altcdr_tx. Simple PLL model with 1 clock input (clk) and
-//               2 clock outputs (clk0 & clk1).
-//
-// Limitations : Only capable of multiplying and dividing the input clock
-//               frequency. There is no support for phase shifts, uneven duty
-//               cycles or other fancy PLL features, since the Mercury CDR
-//               does not need these features.
-//
-// Expected results : 2 output clocks - clk0 and clk1. Locked output indicates

-// Module Name     :    altlvds_rx
-//
-// Description     :   Low Voltage Differential Signaling (LVDS) receiver
-//                     megafunction. The altlvds_rx megafunction implements a
-//                     deserialization receiver. LVDS is a high speed IO interface
-//                     that uses inputs without a reference voltage. LVDS uses
-//                     two wires carrying differential values to create a single
-//                     channel. These wires are connected to two pins on
-//                     supported device to create a single LVDS channel
-//
-// Limitation      :   Only available for APEX20KE, APEXII, MERCURY, STRATIX,
-//                     STRATIX GX, Stratix II, Cyclone and Cyclone II families.
-//
-// Results expected:   output clock, deserialized output data and pll locked
-//                     signal.

-//
-// Module Name     :  altcam
-//
-// Description     :  Content-addressable memory (CAM) Megafunction. The
-// data contained in a CAM is a set of patterns that can be searched in a
-// single-clock cycle. The altcam megafunction allows each stored pattern
-// bit to be specified as a binary "1" bit, binary "0" bit, or a don't care bit.
-// Comparing a stored pattern bit that is specified as don't care with its
-// corresponding input pattern bit will always result in a match.
-//
-// Limitation      :  Input patterns cannot contain don't care bits.
-//
-// Results expected:  If the input pattern given to the CAM matches one
-// of the patterns stored in the CAM, the address of the matching stored
-// pattern is generated.

-// Description      : Triple-Port RAM megafunction. This megafunction implements
-//                    RAM with 1 write port and 2 read ports.
-//
-// Limitation       : This megafunction is provided only for backward 
-//                    compatibility in Stratix designs; instead, Altera® 
-//                    recommends using the altsyncram megafunction.
-//
-//                    For Apex Families,
-//                    Uses one embedded cell per data output bit for 
-//                    Embedded System Block (ESB): APEX 20K, APEX II, 
-//                            ARM-based Excalibur and Mercury devices or
-//                    Embedded Array Block (EAB): ACEX 1K and FLEX 10KE family;
-//
-//                    However, in FLEX 6000, MAX 3000, and MAX 7000 devices, 
-//                    or if the USE_EAB paramter is set to "OFF", uses one 
-//                    logic cell (LCs) per memory bit.
-//
-//
-// Results expected : The alt3pram function represents asynchronous memory 
-//                    or memory with synchronous inputs and/or outputs.

-// Description     :  Parameterized parallel adder megafunction. The data input 
-//                    is a concatenated group of input words.  The size
-//                    parameter indicates the number of 'width'-bit words.
-//
-//                    Each word is added together to generate the result output.
-//                    Each word is left shifted according to the shift
-//                    parameter.  The shift amount is multiplied by the word
-//                    index, with the least significant word being word 0.
-//                    The shift for word I is (shift * I).
-//                   
-//                    The most significant word can be subtracted from the total
-//                    by setting the msw_subtract parameter to 1.
-//                    If the result width is less than is required to show the
-//                    full result, the result output can be aligned to the MSB
-//                    or the LSB of the internal result.  When aligning to the
-//                    MSB, the internally calculated best_result_width is used
-//                    to find the true MSB.
-//                    The input data can be signed or unsigned, and the output
-//                    can be pipelined.
-//
-// Limitations     :  Minimum data width is 1, and at least 2 words are required.
-//
-// Results expected:  result - The sum of all inputs.

-NOTE: It is incumbent upon the command file not to attempt a transaction that
-would cross a 1Kbyte address boundary.
-
-Address is normally updated after each address phase. It is also updated
-during the second cycle of a two cycle retry or split response to rewind the
-address and allow the transaction to be replayed.

-Transaction Details
-
-The transactor pipeline consists of four stages
-
-n_trans - the next transaction from the store
-c_trans - the current control / address stage transaction
-d_trans - the data stage transaction
-rTrans - the completed stage for reporting
-

-c_trans is updated from n_trans when a new transaction begins or from d_trans in

-// Revision 1.5  2003/05/16 10:08:27  mohor
-// Busy was set 2 cycles too late. Reported by Dennis Scott.
-//
-// Revision 1.4  2002/08/14 18:32:10  mohor
-// - Busy signal was not set on time when scan status operation was performed
-// and clock was divided with more than 2.
-// - Nvalid remains valid two more clocks (was previously cleared too soon).
-//
-// Revision 1.3  2002/01/23 10:28:16  mohor
-// Link in the header changed.
-//
-// Revision 1.2  2001/10/19 08:43:51  mohor
-// eth_timescale.v changed to timescale.v This is done because of the
-// simulation of the few cores in a one joined project.
-//
-// Revision 1.1  2001/08/06 14:44:29  mohor
-// A define FPGA added to select between Artisan RAM (for ASIC) and Block Ram (For Virtex).
-// Include files fixed to contain no path.
-// File names and module names changed ta have a eth_ prologue in the name.
-// File eth_timescale.v is used to define timescale
-// All pin names on the top module are changed to contain _I, _O or _OE at the end.
-// Bidirectional signal MDIO is changed to three signals (Mdc_O, Mdi_I, Mdo_O
-// and Mdo_OE. The bidirectional signal must be created on the top level. This
-// is done due to the ASIC tools.
-//
-// Revision 1.2  2001/08/02 09:25:31  mohor
-// Unconnected signals are now connected.
-//
-// Revision 1.1  2001/07/30 21:23:42  mohor
-// Directory structure changed. Files checked and joind together.
-//
-// Revision 1.3  2001/06/01 22:28:56  mohor
-// This files (MIIM) are fully working. They were thoroughly tested. The testbench is not updated.

-// Revision 1.3  2002/01/23 10:28:16  mohor
-// Link in the header changed.
-//
-// Revision 1.2  2001/10/19 08:43:51  mohor
-// eth_timescale.v changed to timescale.v This is done because of the
-// simulation of the few cores in a one joined project.
-//
-// Revision 1.1  2001/08/06 14:44:29  mohor
-// A define FPGA added to select between Artisan RAM (for ASIC) and Block Ram (For Virtex).
-// Include files fixed to contain no path.
-// File names and module names changed ta have a eth_ prologue in the name.
-// File eth_timescale.v is used to define timescale
-// All pin names on the top module are changed to contain _I, _O or _OE at the end.
-// Bidirectional signal MDIO is changed to three signals (Mdc_O, Mdi_I, Mdo_O
-// and Mdo_OE. The bidirectional signal must be created on the top level. This
-// is done due to the ASIC tools.
-//
-// Revision 1.1  2001/07/30 21:23:42  mohor
-// Directory structure changed. Files checked and joind together.
-//
-// Revision 1.3  2001/06/01 22:28:55  mohor
-// This files (MIIM) are fully working. They were thoroughly tested. The testbench is not updated.

-{Hi guys,
-    Thanks for your interest about this tri-speed ethernet MAC controller.
-Since this project was created at 25-Nov-2005,I put almost all my free time
-on this project.I am exhausted for this two month's extra work.If you think
-this project is useful,let me know that and i will feel much better. 
-
-    To increase the flexibility, some optional modules can be removed from 
-the design to reduce area.

-// Revision 1.1  2002/01/25 08:54:56  mohor
-// UART PHY added. Files are fully operational, working on HW.
-//
-//
-//
-//
-//
-
-
-Following files are making an UART16550 PHY and are used for testing:
-
-uart_device_if_defines.v  - defines related to PHY
-uart_device_if_memory.v   - Module for initializing PHY (reading commands from vapi.log file)
-uart_device_if.v          - Uart PHY with additional feature for testing
-vapi.log                  - File with commands (expected data, data to be send, etc.)
-readme.txt                - This file
-
-
-
-
-OPERATION:
-uart_device_if.v is a uart PHY and connects to the uart_top.v. PHY takes commands from vapi.log
-file. Depending on command it can:
-- set a mode (5, 6, 7, 8-bit, parity, stop bits, etc.)
-- set a frequency divider (dll)
-- send a character
-- receive a character and compare it to the expected one
-- send a glitch (after a certain period of time)
-- send a break 
-- detect a break
-- Check if fifo is empty/not empty (and generate an error if expected value differs from actual)
-- delay (does nothing for certain number of characters)
-
-On the other side of uart some kind of host must be connected that controls the phy.
-
-This is the structure:
-
-
- ||||||||||||||              ||||||||||||||||              ||||||||||||||||
- |            |              |              |              |              |
- |   Host     | <----------> |    UART      | <----------> |     PHY      | 
- |            |              |              |              |              |
- ||||||||||||||              ||||||||||||||||              ||||||||||||||||
- 
- 
- PHY must know how host sets th UART and work in the same mode. Besides that it must know what
- host is sending or expecting to receive. Operation of the PHY must be written in the vapi.log
- file.
- 
- When I was using this testing environment, I used OpenRISC1200 as a host. Everything is fully
- operational. UART was also tested in hardware (on two different boards), running uCLinux in
- both, interrupt and polling mode.

-// $Log: uart_device.v,v $
-// Revision 1.1  2004/03/27 03:55:16  tadejm
-// Testbench with complete selfchecking. BUG is that THRE status is set at the end of last sent bit when TX FIFO is empty instead when only TX FIFO gets empty. This causes testcases not to finish.

-// Revision 1.1  2004/03/27 03:55:16  tadejm
-// Testbench with complete selfchecking. BUG is that THRE status is set at the end of last sent bit when TX FIFO is empty instead when only TX FIFO gets empty. This causes testcases not to finish.

-// Revision 1.1  2004/03/27 03:55:16  tadejm
-// Testbench with complete selfchecking. BUG is that THRE status is set at the end of last sent bit when TX FIFO is empty instead when only TX FIFO gets empty. This causes testcases not to finish.

-// Revision 1.1  2004/03/27 03:55:17  tadejm
-// Testbench with complete selfchecking. BUG is that THRE status is set at the end of last sent bit when TX FIFO is empty instead when only TX FIFO gets empty. This causes testcases not to finish.

-//               Updated specification documentation.
-//               Added full 32-bit data bus interface, now as default.
-//               Address is 5-bit wide in 32-bit data bus mode.
-//               Added wb_sel_i input to the core. It's used in the 32-bit mode.
-//               Added debug interface with two 32-bit read-only registers in 32-bit mode.

-Note: This Changes file is being maintained since 25.5.2001.
-
-29.07.2002
-~~~~~~~~~~
-Reverted to have uart_defines.v file to be included in the verilog
-files. It seems that it's been a bad idea in the first place.
-
-22.07.2002
-~~~~~~~~~~
-Notice that this file hasn't been updated for a while so not all changed are present.
-
-Bug Fixes:
- * Possible loss of sync and bad reception of stop bit on slow baud rates fixed.
-  Problem reported by Kenny.Tung.
- * Bad (or lack of ) loopback handling fixed. Reported by Cherry Withers.
-
-Improvements:
- * Made FIFO's as general inferrable memory where possible. 
- So on FPGA they should be inferred as RAM (Distributed RAM on Xilinx).
- This saves about 1/3 of the Slice count and reduces P&R and synthesis times.
-
- * Added optional baudrate output (baud_o). 
- This is identical to BAUDOUT* signal on 16550 chip. 
- It outputs 16xbit_clock_rate - the divided clock.
- It's disabled by default. Define UART_HAS_BAUDRATE_OUTPUT to use.
-
-Note:
- The uart_defines.v file is no longer included in the source files.
- So keep this in mind when doing simulation. Add it manually.
- I've done this, so that you could you your own define files for
- different configurations. I need this for the IrDA core I develop.
- You can just uncomment the `includes if you want the old behaviour.
- The uart_fifo.v file is no longer used. Intead uart_rfifo.v and uart_tfifo.v
- file are now present. Also raminfr.v in the new inferred ram module.
-
- Check the new core and I hope you'll like it.
-
-10.08.2001
-~~~~~~~~~~
-* Modified naming of top signals and defines to be unique and easy to integrate
-* Changed the directory structure of the core to new structure as described in OpenCores 
-  coding guidelines. !!!
-* Fixed (I hope) the detection of break condition  
-* Added top level parameters for data width and address line width
-
-23.06.2001
-~~~~~~~~~~
-
-* With the help of Bob Kirstein another two bugs were fixed:
-   1. Trasmitter was sending stop bit two 16xclock cycle slonger than needed.
-   2. Receiver was losing 1 16xclock cycle on each character and went out of sync.
-
-* Major change: 
-    I have modified the divisor latch register to be 16-bit long instead of 32 as I thought was
-    necessary for higher speed systems. Thanks to Rick Wright for pointing this out.
-    So now, DL3 and DL4 register bytes are not used.
-    Documentation is updated to follow this change.
-
-* Note that more than 1 stop bit in a byte i snot implemented.
-
-2.05.2001
-~~~~~~~~~
-
-* Fixed transmitter and receiver - the start and the stop bits were sent and received complemented.
-  Big thanks go to Bob Kirstein for pointing this out to me.
-
-
-31.05.2001
-~~~~~~~~~~
-
-* Minor changes in register reading code
-* Changed FCR to be 2 bits wide (reset bits are not needed) and instead enabled the rx_reset and tx_reset
-   signals which I forgot to implement.
-* Changed defines for FCR.
-* Cleaned ports that were not connected in top-level.
-* Changed the code to have only one FIFO module instead of two to overcome versioning problem on the cost of
-   some additional gate count. UART_RX_FIFO was modified a little and renamed to UART_FIFO.
-* UART_RX_FIFO.v and UART_TX_FIFO.v files removed from the project.
-* Changes to receiver and transmitter modules concerning FIFO handling.
-* Commented out `include "UART_defines" in all files but UART_top.v and test bench.
-* Modified test bench a little for a little better check.
-
-
-29.05.2001
-~~~~~~~~~~
-
-* Fixed: Line Control Register block didn't have wb_rst_i in its sensitivity list
-* Fixed: Modem Status Register block didn't have wb_rst_i in its sensitivity list and didn't set reset value
-* Fixed rf_pop, lsr_mask, msi_reset and threi_clear not being synthesizable in release 1.7. (Thanks 
-       to Pavel Korenski for pointing this to me)
-
-
-27.05.2001
-~~~~~~~~~~
-
-Thanks to Rick Wright for pointing me many of my bugs.
-
-* Fixed the rf_pop and lsr_mask flags not being deasserted.
-* Fixed Time-Out interrupt not being masked by bit 0 in IER
-* Fixed interrupt logic not being masked by IER
-* Fixed bit 0 (interrupt pending) of IIR being set incorrectly
-* Fixed Modem Status Register bits 3:0 handling (didn't work as should have)
-* Fixed modem status interrupt to be related to bits [3:0] (deltas) instead of the bits 7:4 of MSR.
-   This way the interrupt is cleared upon reading from the MSR.
-* Fixed THRE interrupt not being reset by reading IIR
-* Changed Receiver and Transmitter FIFO, so that they do not use the FIFO_inc.v file because of problems
-  with #include command.
-* Removed FIFO_inc.v from CVS tree.
-
-* Updated specifications .pdf file

-// CVS Revision History
-//
-// $Log: raminfr.v,v $
-// Revision 1.2  2002/07/29 21:16:18  gorban
-// The uart_defines.v file is included again in sources.
-//
-// Revision 1.1  2002/07/22 23:02:23  gorban
-// Bug Fixes:
-//  * Possible loss of sync and bad reception of stop bit on slow baud rates fixed.
-//   Problem reported by Kenny.Tung.
-//  * Bad (or lack of ) loopback handling fixed. Reported by Cherry Withers.
-//
-// Improvements:
-//  * Made FIFO's as general inferrable memory where possible.
-//  So on FPGA they should be inferred as RAM (Distributed RAM on Xilinx).
-//  This saves about 1/3 of the Slice count and reduces P&R and synthesis times.
-//
-//  * Added optional baudrate output (baud_o).

-// CVS Revision History
-//
-// $Log: uart_debug_if.v,v $
-// Revision 1.5  2002/07/29 21:16:18  gorban
-// The uart_defines.v file is included again in sources.
-//
-// Revision 1.4  2002/07/22 23:02:23  gorban
-// Bug Fixes:
-//  * Possible loss of sync and bad reception of stop bit on slow baud rates fixed.
-//   Problem reported by Kenny.Tung.
-//  * Bad (or lack of ) loopback handling fixed. Reported by Cherry Withers.
-//
-// Improvements:
-//  * Made FIFO's as general inferrable memory where possible.
-//  So on FPGA they should be inferred as RAM (Distributed RAM on Xilinx).
-//  This saves about 1/3 of the Slice count and reduces P&R and synthesis times.
-//
-//  * Added optional baudrate output (baud_o).
-//  This is identical to BAUDOUT* signal on 16550 chip.
-//  It outputs 16xbit_clock_rate - the divided clock.
-//  It's disabled by default. Define UART_HAS_BAUDRATE_OUTPUT to use.
-//
-// Revision 1.3  2001/12/19 08:40:03  mohor
-// Warnings fixed (unused signals removed).
-//
-// Revision 1.2  2001/12/12 22:17:30  gorban
-// some synthesis bugs fixed
-//
-// Revision 1.1  2001/12/04 21:14:16  gorban

-// CVS Revision History
-//
-// $Log: uart_defines.v,v $
-// Revision 1.14  2003/09/12 07:26:58  dries
-// adjusted comment + define
-//
-// Revision 1.13  2003/06/11 16:37:47  gorban
-// This fixes errors in some cases when data is being read and put to the FIFO at the same time. Patch is submitted by Scott Furman. Update is very recommended.
-//
-// Revision 1.12  2002/07/22 23:02:23  gorban
-// Bug Fixes:
-//  * Possible loss of sync and bad reception of stop bit on slow baud rates fixed.
-//   Problem reported by Kenny.Tung.
-//  * Bad (or lack of ) loopback handling fixed. Reported by Cherry Withers.
-//
-// Improvements:
-//  * Made FIFO's as general inferrable memory where possible.
-//  So on FPGA they should be inferred as RAM (Distributed RAM on Xilinx).
-//  This saves about 1/3 of the Slice count and reduces P&R and synthesis times.
-//
-//  * Added optional baudrate output (baud_o).
-//  This is identical to BAUDOUT* signal on 16550 chip.
-//  It outputs 16xbit_clock_rate - the divided clock.
-//  It's disabled by default. Define UART_HAS_BAUDRATE_OUTPUT to use.
-//
-// Revision 1.10  2001/12/11 08:55:40  mohor
-// Scratch register define added.
-//
-// Revision 1.9  2001/12/03 21:44:29  gorban
-// Updated specification documentation.
-// Added full 32-bit data bus interface, now as default.
-// Address is 5-bit wide in 32-bit data bus mode.
-// Added wb_sel_i input to the core. It's used in the 32-bit mode.
-// Added debug interface with two 32-bit read-only registers in 32-bit mode.
-// Bits 5 and 6 of LSR are now only cleared on TX FIFO write.
-// My small test bench is modified to work with 32-bit mode.
-//
-// Revision 1.8  2001/11/26 21:38:54  gorban
-// Lots of fixes:
-// Break condition wasn't handled correctly at all.
-// LSR bits could lose their values.
-// LSR value after reset was wrong.
-// Timing of THRE interrupt signal corrected.
-// LSR bit 0 timing corrected.
-//
-// Revision 1.7  2001/08/24 21:01:12  mohor
-// Things connected to parity changed.
-// Clock devider changed.
-//
-// Revision 1.6  2001/08/23 16:05:05  mohor
-// Stop bit bug fixed.
-// Parity bug fixed.
-// WISHBONE read cycle bug fixed,
-// OE indicator (Overrun Error) bug fixed.
-// PE indicator (Parity Error) bug fixed.
-// Register read bug fixed.
-//
-// Revision 1.5  2001/05/31 20:08:01  gorban
-// FIFO changes and other corrections.
-//
-// Revision 1.4  2001/05/21 19:12:02  gorban
-// Corrected some Linter messages.
-//
-// Revision 1.3  2001/05/17 18:34:18  gorban
-// First 'stable' release. Should be sythesizable now. Also added new header.
-//
-// Revision 1.0  2001-05-17 21:27:11+02  jacob
-// Initial revision
-//
-//
-
-// remove comments to restore to use the new version with 8 data bit interface
-// in 32bit-bus mode, the wb_sel_i signal is used to put data in correct place
-// also, in 8-bit version there'll be no debugging features included
-// CAUTION: doesn't work with current version of OR1200

-// $Log: uart_receiver.v,v $
-// Revision 1.31  2004/06/18 14:46:15  tadejm
-// Brandl Tobias repaired a bug regarding frame error in receiver when brake is received.
-//
-// Revision 1.29  2002/07/29 21:16:18  gorban
-// The uart_defines.v file is included again in sources.
-//
-// Revision 1.28  2002/07/22 23:02:23  gorban
-// Bug Fixes:
-//  * Possible loss of sync and bad reception of stop bit on slow baud rates fixed.
-//   Problem reported by Kenny.Tung.
-//  * Bad (or lack of ) loopback handling fixed. Reported by Cherry Withers.
-//
-// Improvements:
-//  * Made FIFO's as general inferrable memory where possible.
-//  So on FPGA they should be inferred as RAM (Distributed RAM on Xilinx).
-//  This saves about 1/3 of the Slice count and reduces P&R and synthesis times.
-//
-//  * Added optional baudrate output (baud_o).
-//  This is identical to BAUDOUT* signal on 16550 chip.
-//  It outputs 16xbit_clock_rate - the divided clock.
-//  It's disabled by default. Define UART_HAS_BAUDRATE_OUTPUT to use.
-//
-// Revision 1.27  2001/12/30 20:39:13  mohor
-// More than one character was stored in case of break. End of the break
-// was not detected correctly.
-//
-// Revision 1.26  2001/12/20 13:28:27  mohor
-// Missing declaration of rf_push_q fixed.
-//
-// Revision 1.25  2001/12/20 13:25:46  mohor
-// rx push changed to be only one cycle wide.
-//
-// Revision 1.24  2001/12/19 08:03:34  mohor
-// Warnings cleared.
-//
-// Revision 1.23  2001/12/19 07:33:54  mohor
-// Synplicity was having troubles with the comment.
-//
-// Revision 1.22  2001/12/17 14:46:48  mohor
-// overrun signal was moved to separate block because many sequential lsr
-// reads were preventing data from being written to rx fifo.
-// underrun signal was not used and was removed from the project.
-//
-// Revision 1.21  2001/12/13 10:31:16  mohor
-// timeout irq must be set regardless of the rda irq (rda irq does not reset the
-// timeout counter).
-//
-// Revision 1.20  2001/12/10 19:52:05  gorban
-// Igor fixed break condition bugs
-//
-// Revision 1.19  2001/12/06 14:51:04  gorban
-// Bug in LSR[0] is fixed.
-// All WISHBONE signals are now sampled, so another wait-state is introduced on all transfers.
-//
-// Revision 1.18  2001/12/03 21:44:29  gorban
-// Updated specification documentation.
-// Added full 32-bit data bus interface, now as default.
-// Address is 5-bit wide in 32-bit data bus mode.
-// Added wb_sel_i input to the core. It's used in the 32-bit mode.
-// Added debug interface with two 32-bit read-only registers in 32-bit mode.
-// Bits 5 and 6 of LSR are now only cleared on TX FIFO write.
-// My small test bench is modified to work with 32-bit mode.
-//
-// Revision 1.17  2001/11/28 19:36:39  gorban
-// Fixed: timeout and break didn't pay attention to current data format when counting time
-//
-// Revision 1.16  2001/11/27 22:17:09  gorban
-// Fixed bug that prevented synthesis in uart_receiver.v
-//
-// Revision 1.15  2001/11/26 21:38:54  gorban
-// Lots of fixes:
-// Break condition wasn't handled correctly at all.
-// LSR bits could lose their values.
-// LSR value after reset was wrong.
-// Timing of THRE interrupt signal corrected.
-// LSR bit 0 timing corrected.
-//
-// Revision 1.14  2001/11/10 12:43:21  gorban
-// Logic Synthesis bugs fixed. Some other minor changes
-//
-// Revision 1.13  2001/11/08 14:54:23  mohor
-// Comments in Slovene language deleted, few small fixes for better work of
-// old tools. IRQs need to be fix.
-//
-// Revision 1.12  2001/11/07 17:51:52  gorban
-// Heavily rewritten interrupt and LSR subsystems.
-// Many bugs hopefully squashed.

-// CVS Revision History
-//
-// $Log: uart_regs.v,v $
-// Revision 1.42  2004/11/22 09:21:59  igorm
-// Timeout interrupt should be generated only when there is at least ony
-// character in the fifo.
-//
-// Revision 1.41  2004/05/21 11:44:41  tadejm
-// Added synchronizer flops for RX input.
-//
-// Revision 1.40  2003/06/11 16:37:47  gorban
-// This fixes errors in some cases when data is being read and put to the FIFO at the same time. Patch is submitted by Scott Furman. Update is very recommended.
-//
-// Revision 1.39  2002/07/29 21:16:18  gorban
-// The uart_defines.v file is included again in sources.
-//
-// Revision 1.38  2002/07/22 23:02:23  gorban
-// Bug Fixes:
-//  * Possible loss of sync and bad reception of stop bit on slow baud rates fixed.
-//   Problem reported by Kenny.Tung.
-//  * Bad (or lack of ) loopback handling fixed. Reported by Cherry Withers.
-//
-// Improvements:
-//  * Made FIFO's as general inferrable memory where possible.
-//  So on FPGA they should be inferred as RAM (Distributed RAM on Xilinx).
-//  This saves about 1/3 of the Slice count and reduces P&R and synthesis times.
-//
-//  * Added optional baudrate output (baud_o).
-//  This is identical to BAUDOUT* signal on 16550 chip.
-//  It outputs 16xbit_clock_rate - the divided clock.
-//  It's disabled by default. Define UART_HAS_BAUDRATE_OUTPUT to use.
-//
-// Revision 1.37  2001/12/27 13:24:09  mohor
-// lsr[7] was not showing overrun errors.
-//
-// Revision 1.36  2001/12/20 13:25:46  mohor
-// rx push changed to be only one cycle wide.
-//
-// Revision 1.35  2001/12/19 08:03:34  mohor
-// Warnings cleared.
-//
-// Revision 1.34  2001/12/19 07:33:54  mohor
-// Synplicity was having troubles with the comment.
-//
-// Revision 1.33  2001/12/17 10:14:43  mohor
-// Things related to msr register changed. After THRE IRQ occurs, and one
-// character is written to the transmit fifo, the detection of the THRE bit in the
-// LSR is delayed for one character time.
-//
-// Revision 1.32  2001/12/14 13:19:24  mohor
-// MSR register fixed.
-//
-// Revision 1.31  2001/12/14 10:06:58  mohor
-// After reset modem status register MSR should be reset.
-//
-// Revision 1.30  2001/12/13 10:09:13  mohor
-// thre irq should be cleared only when being source of interrupt.
-//
-// Revision 1.29  2001/12/12 09:05:46  mohor
-// LSR status bit 0 was not cleared correctly in case of reseting the FCR (rx fifo).
-//
-// Revision 1.28  2001/12/10 19:52:41  gorban
-// Scratch register added
-//
-// Revision 1.27  2001/12/06 14:51:04  gorban
-// Bug in LSR[0] is fixed.
-// All WISHBONE signals are now sampled, so another wait-state is introduced on all transfers.
-//
-// Revision 1.26  2001/12/03 21:44:29  gorban
-// Updated specification documentation.
-// Added full 32-bit data bus interface, now as default.
-// Address is 5-bit wide in 32-bit data bus mode.
-// Added wb_sel_i input to the core. It's used in the 32-bit mode.
-// Added debug interface with two 32-bit read-only registers in 32-bit mode.
-// Bits 5 and 6 of LSR are now only cleared on TX FIFO write.

-// CVS Revision History
-//
-// $Log: uart_rfifo.v,v $
-// Revision 1.4  2003/07/11 18:20:26  gorban
-// added clearing the receiver fifo statuses on resets
-//
-// Revision 1.3  2003/06/11 16:37:47  gorban
-// This fixes errors in some cases when data is being read and put to the FIFO at the same time. Patch is submitted by Scott Furman. Update is very recommended.
-//
-// Revision 1.2  2002/07/29 21:16:18  gorban
-// The uart_defines.v file is included again in sources.
-//
-// Revision 1.1  2002/07/22 23:02:23  gorban
-// Bug Fixes:
-//  * Possible loss of sync and bad reception of stop bit on slow baud rates fixed.
-//   Problem reported by Kenny.Tung.
-//  * Bad (or lack of ) loopback handling fixed. Reported by Cherry Withers.
-//
-// Improvements:
-//  * Made FIFO's as general inferrable memory where possible.
-//  So on FPGA they should be inferred as RAM (Distributed RAM on Xilinx).
-//  This saves about 1/3 of the Slice count and reduces P&R and synthesis times.
-//
-//  * Added optional baudrate output (baud_o).
-//  This is identical to BAUDOUT* signal on 16550 chip.
-//  It outputs 16xbit_clock_rate - the divided clock.
-//  It's disabled by default. Define UART_HAS_BAUDRATE_OUTPUT to use.
-//
-// Revision 1.16  2001/12/20 13:25:46  mohor
-// rx push changed to be only one cycle wide.
-//
-// Revision 1.15  2001/12/18 09:01:07  mohor
-// Bug that was entered in the last update fixed (rx state machine).
-//
-// Revision 1.14  2001/12/17 14:46:48  mohor
-// overrun signal was moved to separate block because many sequential lsr
-// reads were preventing data from being written to rx fifo.
-// underrun signal was not used and was removed from the project.
-//
-// Revision 1.13  2001/11/26 21:38:54  gorban
-// Lots of fixes:
-// Break condition wasn't handled correctly at all.
-// LSR bits could lose their values.
-// LSR value after reset was wrong.
-// Timing of THRE interrupt signal corrected.
-// LSR bit 0 timing corrected.
-//
-// Revision 1.12  2001/11/08 14:54:23  mohor
-// Comments in Slovene language deleted, few small fixes for better work of
-// old tools. IRQs need to be fix.
-//
-// Revision 1.11  2001/11/07 17:51:52  gorban
-// Heavily rewritten interrupt and LSR subsystems.
-// Many bugs hopefully squashed.
-//
-// Revision 1.10  2001/10/20 09:58:40  gorban
-// Small synopsis fixes
-//
-// Revision 1.9  2001/08/24 21:01:12  mohor
-// Things connected to parity changed.
-// Clock devider changed.
-//
-// Revision 1.8  2001/08/24 08:48:10  mohor
-// FIFO was not cleared after the data was read bug fixed.
-//
-// Revision 1.7  2001/08/23 16:05:05  mohor
-// Stop bit bug fixed.
-// Parity bug fixed.
-// WISHBONE read cycle bug fixed,
-// OE indicator (Overrun Error) bug fixed.
-// PE indicator (Parity Error) bug fixed.
-// Register read bug fixed.
-//
-// Revision 1.3  2001/05/31 20:08:01  gorban
-// FIFO changes and other corrections.
-//
-// Revision 1.3  2001/05/27 17:37:48  gorban
-// Fixed many bugs. Updated spec. Changed FIFO files structure. See CHANGES.txt file.
-//
-// Revision 1.2  2001/05/17 18:34:18  gorban
-// First 'stable' release. Should be sythesizable now. Also added new header.
-//

-// CVS Revision History
-//
-// $Log: uart_tfifo.v,v $
-// Revision 1.2  2002/07/29 21:16:18  gorban
-// The uart_defines.v file is included again in sources.
-//
-// Revision 1.1  2002/07/22 23:02:23  gorban
-// Bug Fixes:
-//  * Possible loss of sync and bad reception of stop bit on slow baud rates fixed.
-//   Problem reported by Kenny.Tung.
-//  * Bad (or lack of ) loopback handling fixed. Reported by Cherry Withers.
-//
-// Improvements:
-//  * Made FIFO's as general inferrable memory where possible.
-//  So on FPGA they should be inferred as RAM (Distributed RAM on Xilinx).
-//  This saves about 1/3 of the Slice count and reduces P&R and synthesis times.
-//
-//  * Added optional baudrate output (baud_o).
-//  This is identical to BAUDOUT* signal on 16550 chip.
-//  It outputs 16xbit_clock_rate - the divided clock.
-//  It's disabled by default. Define UART_HAS_BAUDRATE_OUTPUT to use.
-//
-// Revision 1.16  2001/12/20 13:25:46  mohor
-// rx push changed to be only one cycle wide.
-//
-// Revision 1.15  2001/12/18 09:01:07  mohor
-// Bug that was entered in the last update fixed (rx state machine).
-//
-// Revision 1.14  2001/12/17 14:46:48  mohor
-// overrun signal was moved to separate block because many sequential lsr
-// reads were preventing data from being written to rx fifo.
-// underrun signal was not used and was removed from the project.
-//
-// Revision 1.13  2001/11/26 21:38:54  gorban
-// Lots of fixes:
-// Break condition wasn't handled correctly at all.
-// LSR bits could lose their values.
-// LSR value after reset was wrong.
-// Timing of THRE interrupt signal corrected.
-// LSR bit 0 timing corrected.
-//
-// Revision 1.12  2001/11/08 14:54:23  mohor
-// Comments in Slovene language deleted, few small fixes for better work of
-// old tools. IRQs need to be fix.
-//
-// Revision 1.11  2001/11/07 17:51:52  gorban
-// Heavily rewritten interrupt and LSR subsystems.
-// Many bugs hopefully squashed.
-//
-// Revision 1.10  2001/10/20 09:58:40  gorban
-// Small synopsis fixes
-//
-// Revision 1.9  2001/08/24 21:01:12  mohor
-// Things connected to parity changed.
-// Clock devider changed.
-//
-// Revision 1.8  2001/08/24 08:48:10  mohor
-// FIFO was not cleared after the data was read bug fixed.
-//
-// Revision 1.7  2001/08/23 16:05:05  mohor
-// Stop bit bug fixed.
-// Parity bug fixed.
-// WISHBONE read cycle bug fixed,
-// OE indicator (Overrun Error) bug fixed.
-// PE indicator (Parity Error) bug fixed.
-// Register read bug fixed.
-//
-// Revision 1.3  2001/05/31 20:08:01  gorban
-// FIFO changes and other corrections.
-//
-// Revision 1.3  2001/05/27 17:37:48  gorban
-// Fixed many bugs. Updated spec. Changed FIFO files structure. See CHANGES.txt file.
-//
-// Revision 1.2  2001/05/17 18:34:18  gorban
-// First 'stable' release. Should be sythesizable now. Also added new header.
-//

-// All WISHBONE signals are now sampled, so another wait-state is introduced on all transfers.
-//
-// Revision 1.15  2001/12/03 21:44:29  gorban
-// Updated specification documentation.
-// Added full 32-bit data bus interface, now as default.
-// Address is 5-bit wide in 32-bit data bus mode.
-// Added wb_sel_i input to the core. It's used in the 32-bit mode.
-// Added debug interface with two 32-bit read-only registers in 32-bit mode.
-// Bits 5 and 6 of LSR are now only cleared on TX FIFO write.
-// My small test bench is modified to work with 32-bit mode.
-//
-// Revision 1.14  2001/11/07 17:51:52  gorban
-// Heavily rewritten interrupt and LSR subsystems.
-// Many bugs hopefully squashed.
-//
-// Revision 1.13  2001/10/20 09:58:40  gorban
-// Small synopsis fixes
-//

-// $Log: uart_transmitter.v,v $
-// Revision 1.19  2002/07/29 21:16:18  gorban
-// The uart_defines.v file is included again in sources.
-//
-// Revision 1.18  2002/07/22 23:02:23  gorban
-// Bug Fixes:
-//  * Possible loss of sync and bad reception of stop bit on slow baud rates fixed.
-//   Problem reported by Kenny.Tung.
-//  * Bad (or lack of ) loopback handling fixed. Reported by Cherry Withers.
-//
-// Improvements:
-//  * Made FIFO's as general inferrable memory where possible.
-//  So on FPGA they should be inferred as RAM (Distributed RAM on Xilinx).
-//  This saves about 1/3 of the Slice count and reduces P&R and synthesis times.
-//
-//  * Added optional baudrate output (baud_o).
-//  This is identical to BAUDOUT* signal on 16550 chip.
-//  It outputs 16xbit_clock_rate - the divided clock.
-//  It's disabled by default. Define UART_HAS_BAUDRATE_OUTPUT to use.
-//
-// Revision 1.16  2002/01/08 11:29:40  mohor
-// tf_pop was too wide. Now it is only 1 clk cycle width.
-//
-// Revision 1.15  2001/12/17 14:46:48  mohor
-// overrun signal was moved to separate block because many sequential lsr
-// reads were preventing data from being written to rx fifo.
-// underrun signal was not used and was removed from the project.
-//
-// Revision 1.14  2001/12/03 21:44:29  gorban
-// Updated specification documentation.
-// Added full 32-bit data bus interface, now as default.
-// Address is 5-bit wide in 32-bit data bus mode.
-// Added wb_sel_i input to the core. It's used in the 32-bit mode.
-// Added debug interface with two 32-bit read-only registers in 32-bit mode.
-// Bits 5 and 6 of LSR are now only cleared on TX FIFO write.
-// My small test bench is modified to work with 32-bit mode.
-//
-// Revision 1.13  2001/11/08 14:54:23  mohor
-// Comments in Slovene language deleted, few small fixes for better work of
-// old tools. IRQs need to be fix.
-//
-// Revision 1.12  2001/11/07 17:51:52  gorban
-// Heavily rewritten interrupt and LSR subsystems.
-// Many bugs hopefully squashed.
-//
-// Revision 1.11  2001/10/29 17:00:46  gorban
-// fixed parity sending and tx_fifo resets over- and underrun
-//
-// Revision 1.10  2001/10/20 09:58:40  gorban
-// Small synopsis fixes
-//
-// Revision 1.9  2001/08/24 21:01:12  mohor
-// Things connected to parity changed.
-// Clock devider changed.
-//
-// Revision 1.8  2001/08/23 16:05:05  mohor
-// Stop bit bug fixed.
-// Parity bug fixed.
-// WISHBONE read cycle bug fixed,
-// OE indicator (Overrun Error) bug fixed.
-// PE indicator (Parity Error) bug fixed.
-// Register read bug fixed.
-//
-// Revision 1.6  2001/06/23 11:21:48  gorban
-// DL made 16-bit long. Fixed transmission/reception bugs.
-//
-// Revision 1.5  2001/06/02 14:28:14  gorban
-// Fixed receiver and transmitter. Major bug fixed.
-//
-// Revision 1.4  2001/05/31 20:08:01  gorban
-// FIFO changes and other corrections.
-//
-// Revision 1.3  2001/05/27 17:37:49  gorban
-// Fixed many bugs. Updated spec. Changed FIFO files structure. See CHANGES.txt file.
-//
-// Revision 1.2  2001/05/21 19:12:02  gorban
-// Corrected some Linter messages.
-//
-// Revision 1.1  2001/05/17 18:34:18  gorban
-// First 'stable' release. Should be sythesizable now. Also added new header.

-// CVS Revision History
-//
-// $Log: uart_wb.v,v $
-// Revision 1.17  2004/05/21 12:35:15  tadejm
-// Added 2 LSB address generation dependent on select lines and LITLE/BIG endian when UART is in 32-bit mode.
-//
-// Revision 1.16  2002/07/29 21:16:18  gorban
-// The uart_defines.v file is included again in sources.
-//
-// Revision 1.15  2002/07/22 23:02:23  gorban
-// Bug Fixes:
-//  * Possible loss of sync and bad reception of stop bit on slow baud rates fixed.
-//   Problem reported by Kenny.Tung.
-//  * Bad (or lack of ) loopback handling fixed. Reported by Cherry Withers.
-//
-// Improvements:
-//  * Made FIFO's as general inferrable memory where possible.
-//  So on FPGA they should be inferred as RAM (Distributed RAM on Xilinx).
-//  This saves about 1/3 of the Slice count and reduces P&R and synthesis times.
-//
-//  * Added optional baudrate output (baud_o).
-//  This is identical to BAUDOUT* signal on 16550 chip.
-//  It outputs 16xbit_clock_rate - the divided clock.
-//  It's disabled by default. Define UART_HAS_BAUDRATE_OUTPUT to use.
-//
-// Revision 1.12  2001/12/19 08:03:34  mohor
-// Warnings cleared.
-//
-// Revision 1.11  2001/12/06 14:51:04  gorban
-// Bug in LSR[0] is fixed.
-// All WISHBONE signals are now sampled, so another wait-state is introduced on all transfers.
-//
-// Revision 1.10  2001/12/03 21:44:29  gorban
-// Updated specification documentation.
-// Added full 32-bit data bus interface, now as default.
-// Address is 5-bit wide in 32-bit data bus mode.
-// Added wb_sel_i input to the core. It's used in the 32-bit mode.
-// Added debug interface with two 32-bit read-only registers in 32-bit mode.
-// Bits 5 and 6 of LSR are now only cleared on TX FIFO write.
-// My small test bench is modified to work with 32-bit mode.
-//
-// Revision 1.9  2001/10/20 09:58:40  gorban
-// Small synopsis fixes
-//
-// Revision 1.8  2001/08/24 21:01:12  mohor
-// Things connected to parity changed.
-// Clock devider changed.
-//
-// Revision 1.7  2001/08/23 16:05:05  mohor
-// Stop bit bug fixed.
-// Parity bug fixed.
-// WISHBONE read cycle bug fixed,
-// OE indicator (Overrun Error) bug fixed.
-// PE indicator (Parity Error) bug fixed.
-// Register read bug fixed.
-//
-// Revision 1.4  2001/05/31 20:08:01  gorban
-// FIFO changes and other corrections.
-//
-// Revision 1.3  2001/05/21 19:12:01  gorban
-// Corrected some Linter messages.
-//
-// Revision 1.2  2001/05/17 18:34:18  gorban
-// First 'stable' release. Should be sythesizable now. Also added new header.
-//
-// Revision 1.0  2001-05-17 21:27:13+02  jacob

-//  Description
-//     1. Up to 8 masters and 8 slaves share bus Wishbone connection
-//     2. no priorty arbitor , 8 masters are processed in a round
-//        robin way,
-//     3. if WB_USE_TRISTATE was defined, the share bus is a tristate
-//        bus, and use less logic resource.
-//     4. wb_conbus was synthesis to XC2S100-5-PQ208 using synplify,
-//     Max speed >60M , and 374 SLICE if using Multiplexor bus
-//             or 150 SLICE if using tri-state bus.
