Abstract

A method and computer program for estimating a cell delay for an integrated circuit design include steps of selecting a range of values for cell ramptime and load and a range of values for an additional cell parameter. The values for cell ramptime, load, and the additional cell parameter are arranged in a lookup table. A cell delay is calculated for each combination of cell ramptime, load, and the additional cell parameter for the lookup table.
