Multiple Edge Responses for Fast and Accurate System Simulations

Abstract

Fast and accurate simulation of the system response is important in high-speed I/O system design because performance is severely limited by channel ISI and random noise. This paper presents a novel way to simulate the signal response given an arbitrary bit pattern using multiple edge responses (MER). The presented method provides an accuracy improvement over the traditional approaches which either uses the superposition of single bit response (SBR) or double edge response (DER), while maintaining the equivalent numerical efficiency
