Abstract :
Asymptotic waveform evaluation (AWE) is a novel method to analyze linear(ized) circuits. It uses a form of Pade approximation rather than numerical integration to approximate the behavior of linear(ized) circuits in either the time or the frequency domain. Improvements are presented to the theory of AWE to avoid some inherent limitations of Pade approximation. A discussion is presented of the practical aspects that have arisen in the attempt to use AWE in a simulation program called AWEsim. Results are also presented of AWEsim that clearly demonstrate the advantage of AWE over traditional approaches to circuit simulation.<>
