BUSTLE, a new circuit simulation tool

Abstract

A new circuit simulation tool, BUSTLE, using Asymptotic Waveform Evaluation (AWE) technique and Piece-wise Linear (PW L) models, is implemented. The results are very promising, especially for large circuits. This piece of work, in cooperation with [1], explains the techniques used in the simulator BUSTLE, such as • efficient LU decomposition of the sparse matrices, • using derivative and integral moments in order to get rid of the instability problem, • combining the PWL approach with AWE in transient analysis, and illustrates some simulation results.
