IMPLEMENTATION OF FAULT SIMULATION TECHNIQUES

Abstract

Advances in digital technology has led to an increase of circuit complexity and its size in terms of the number of gates used. So it has become essential to use computer aided design and testing of digital circuits. One of the basic tools for this is fault simulation,. Various fault simulation techniques and their alter-natives have been proposed in literature. In this work Parallel Simulation, Deductive Simulation, (Priti.calpath tracing and statistical fault analysis have been implemented on DW 2050. The implementations are valid for combinational circuits. The single-stuck'-at fault model has been used. The results have been presented in terms of the C.F.U. requirements of the different techniques. The results indicate that parallel simulation requires minimum C.P.U. time.
