Have I really met timing? - validating primetime timing reports with SPICE

At sign-off everybody is wondering about how good the accuracy of the static timing analysis timing reports generated with PrimeTime ® really is. Errors can be introduced by STA setup, interconnect modeling, library characterization etc. The claims that path timing calculated by PrimeTime usually is within a few percent of Spice don’t help to ease your uncertainty. When the Signal Integrity features were introduced to PrimeTime there was also a feature added that was hardly announced: PrimeTime can write out timing paths for simulation with Spice that can be used to validate the timing numbers calculated by PrimeTime. By comparing the numbers calculated by PrimeTime to a simulation
