An efficient method for transient simulation of high-speed interconnects with nonlinear terminations

Abstract

This paper presents a new method for a circuit-based transient simulation of large interconnects circuits terminated with nonlinear devices. The proposed method is based on high-order A-stable integration methods, known as Obreshkov-formula. The new method exploits the structure of the matrices resulting from applying Obreshkov-formula to achieve very high speedups. A numerical example is presented that shows the performance and accuracy of the proposed method.
