Patent ID: 7272807

Claim:
A method of generating an equivalent waveform of a distorted input waveform for an element in an integrated circuit design, the method being performed in a computer, the method comprising: automatically generating a first non-distorted input waveform for the element; automatically computing a transition quantity for the first non-distorted input waveform that is required for the element to produce an output waveform, the transition quantity being determined during a first transition period; automatically determining the end of a second transition period during which the distorted input waveform accumulates the same transition quantity; and automatically computing a second non-distorted input waveform having the same transition quantity as the distorted input waveform, the second non-distorted input waveform having a transition period that terminates at the same time as the end of the second transition period, wherein the second non-distorted input waveform is the equivalent waveform.
