摘要
A method performs statistical static timing analysis of a network that includes a phase-locked loop and a feedback path. The feedback path comprises a set of delays operatively connected from the output of the phase-locked loop back to the input of the phase-locked loop. One embodiment herein computes a statistical feedback path delay for the feedback path. The method can use a separate statistical parameter to represent random uncorrelated delay variation for each delay in the feedback path. The method also computes an output arrival time for the phase-locked loop based on the negative of the statistical feedback path delay.
