Abstract

This paper describes a circuit analysis program aimed at quickly solving linear interconnection circuits with inductance and coupling. It computes circuit responses to varying degrees of detail, varying from a simple Elmore delay to a good waveform estimate. Allowable circuit forms are much more flexible than for existing Elmore delay algorithms. Large networks or distributed lines can be reduced to a form of transfer function that can subsequently be analyzed much more efficiently with the waveform moment methods.
