Claim Text:
1. A non-transitory computer readable storage medium storing instructions for performing static timing analysis of an integrated circuit design for manufacturing, the instructions for: receiving, by a static timing analyzer, information describing a distorted input waveform, the distorted input waveform received as input to a cell of the integrated circuit design for performing timing analysis of the integrated circuit design, the integrated circuit design for manufacturing; determining, by the static timing analyzer, a transition time of the distorted input waveform; receiving, by the static timing analyzer, information describing a nominal input waveform based on the determined transition time and a corresponding nominal output waveform, the nominal output waveform representing output of the cell of the integrated circuit design; computing, by the static timing analyzer, an input waveform distortion as a difference between the distorted input waveform and the nominal input waveform; generating, by the static timing analyzer, an augmented circuit based on the nominal input waveform and the input waveform distortion; and computing an output waveform distortion for the output of the cell of the integrated circuit design based on the augmented circuit.
