Consistent Timing Constraints with PrimeTimeSteve GolsonTrilobyte Systems388 Stearns StreetCarlisle MA 01741 Phone: + : implementation tools are usuallytiming-driven. They requiretiming Constraints forreliable, repeatable, and successful operation. Generating and verifying these Constraints is afamiliar yet sometimes tedious task for the physical implementation introduce the idea ofconsistent Timing Constraints and show how PrimeTime can be used tocreate and manage Timing constraint files needed for all other implementation tools, fromsynthesis to place-and-route to final chip San Jose 20092 Consistent Timing Constraints with IntroductionPhysical implementationmeans transforming an abstract RTL description of an integrated circuitinto a physically-realizable representation of the same circuit.
PrimeTime has a specific behavior that is discussed in the documentation for the various path exception commands. Here is an excerpt from the set_multicycle_path manpage:
