-Continuation Mode:
-The outputs of this block will alias the inputs of the pad sink specified by "pad sink id".
-
-Hierarchical Mode:
The outputs of this block will become the inputs to this flow graph when it is instantiated as a hierarchical block. \
Limit one source pad block per flow graph. \
The "pad sink id" will be ignored in this mode.
## The port name should be the id of the parent block.
## However, port names for IO pads should be self.
