Waveform moment methods for improved interconnection analysis

A circuit analysis program is described 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. The algorithms are based on a new moment polynomial nodal analysis (MPNA) technique that solves for a circuit response with nodal analysis matrix techniques. 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.<>
