System and method for efficient statistical timing analysis of cycle time independent tests

摘要

A computer program product for performing selected timing comparisons in a digital electronic design includes propagating from signal sources to timing comparisons of one or multiple signal labels. The signal label includes signal source identifiers and signal path cycle adjust information. Timing comparisons are determined in which signal label values at each input of the timing comparison are required to compute the selected timing comparisons. The propagation back from the timing comparisons are needed signal labels, followed by the propagation and computing timing data from the signal source applied to the propagated signal labels corresponding to the required signal labels.
