AWESpice: a general tool for the accurate and efficient simulation of interconnect problems

Abstract

AWESpice is a tool for the efficient and accurate simulation of circuits dominated by interconnect. It accepts a general nonlinear circuit and uses the asymptotic waveform evaluation (AWE) algorithm to efficiently convert its linear interconnect portion into multiport admittance macromodels. The macromodels are then simulated in conjunction with the nonlinear devices using a modified version of the SPICE algorithm. This technique leads to a significant reduction in CPU time while retaining the benefits of a conventional circuit simulator. Some examples that have been run to show the accuracy and efficiency of AWESpice on a variety of interconnect problems are presented. >
