System and method for improved accuracy of standard cell timing models

摘要

A computer-based method for estimating cell performance is provided. The method comprises determining a correlation function between a known set of delay times over a range of load values of a first cell and a known set of delay times over the range of load values of a second cell. The method further comprises calculating a delay time of the second cell at a predetermined load value based upon the correlation function and a known delay time of the first cell at the predetermined load value. In another embodiment, the method further comprises determining a generalized slew rate correlation function and calculating a new delay time of the second cell based upon the generalized slew rate correlation function as well.
