Execute the step.
Test on previous steps. They checks if schedule and connection binding have been performed. If they didn't, circuit cannot be created.
Test on memory allocation
main circuit type
top circuit creation
Set some descriptions and legal stuff
add clock and reset to circuit. It increments in_port number and update in_port_map
add all input ports
add registers, connecting them to clock and reset ports
allocate functional units
allocate interconnections
circuit is now complete. circuit manager can be initialized and dot representation can be created
