VCC Software Export

• Current (Amazon) release of Whitebox -C
  Simulation -gt Implementation has a number of
  known limitations/problems with the translation
  of particular C constructs. All known Whitebox-C
  implementation PCRs are scheduled to be fixed for
  the Seine release.
• Currently Lynx does not support partially mapped
  designs. All blocks in behavior are mapped to at
  least something in the architecture.
• The Links to Implementation rely on simulation
  for the generation of type header files.
• For our CRC example, functions declared within
  the file scope are added the id parameter which
  should not happen.
• Solution?
• Write Black box-C implementation.
• Figure out the limitations and try to avoid them
  in the behavior c code.
• Max Chiodo is coming tomorrow to help us out.

VCC Implementation flow- Hardware
White C

• Synthesis result for the Physical send block.
• Total cell area 15624.000000
• The longest path 6.13 ns

stateflow
sf2vhdl

• Overall process pretty straight forward
• sd2vhd tool was broken for the condition action
  statements.
• Stateflow has to be converted from Mealy to Moore
  form.
