  62 This is a sink pad block for creating hierarchical flow graphs. \
  63 The inputs of this block will become the outputs to this flow graph when it is instantiated as a hierarchical block. \
  64 Limit one sink pad block per flow graph.
  65
  66 Remember to set the generate options to hier block.
