Simplified Delay Extraction-Based Passive Transmission Line Macromodeling Algorithm

Abstract

With higher operating frequencies, signal integrity and interconnect analysis in high-speed designs is becoming increasingly important. Recently, a passive delay extraction-based macromodeling algorithm (DEPACT) has been presented for simulation of long lossy coupled lines. In this paper, a new macromodeling algorithm based on DEPACT is introduced to handle several practical cases of importance, resulting in a simple and compact implementation in SPICE-like circuit simulators. The accuracy and efficiency of the proposed algorithm are validated using several practical examples.
