An efficient program for analysis of interconnect circuits

A circuit simulation program using generalized asymptotic waveform evaluation techniques is introduced. The program analyses circuits with lumped and distributed components. It computes the moments at a few frequency points, and extracts the coefficients of an approximating rational by matching the moments simultaneously. The accuracy of the results and the execution times are compared with conventional simulators using several examples, indicating that our simulator provides a speed improvement without a significant loss of accuracy.
