Parallel Simulation of Transmission Line Systems on Printed Circuit Boards

Abstract

The simulation of lossy transmission lines in time domain is a very time consuming task. It requires numerical convolutions and the solution of linear equation systems. In this paper a model for lossy transmission lines and an algorithm for the simulation of these lines is developed. Based on this an approach for parallel simulation of lossy transmission lines is presented. As this approach covers all time consuming tasks of the simulation algorithm a good speed up compared to a single processor solution is expected. KEY WORDS : parallel simulation, lossy transmission lines, discrete convolution, lock step synchronization, message based multiprocessor application 1. Introduction Due to the raising complexity and increasing clock rates of electronic designs the analysis of complex transmission line structures with regard to reflection and crosstalk effects is becoming increasingly important. This type of simulation requires a large computational effort especially if losses of the tran..
