The aim of this work is to report on a parallel implementation of methods for tolerance analysis in the framework of a microelectronics design center.The methods were designed to run parallelly on different platforms which could have different computational performances.In order to distributed the computations over a network of workstations,the algorithm was designed not by using a parallel compiler,but by using a RPC multi-server network.We have used essentially two methods.This first is the Monte Carlo approach,the second is based on an approximation by numerical integration or quadrature technique[1,2,3,4],which requires far less function evaluations than the Monte Carlo method.These two approaches have been implemented in a parallel algorithm to be used on a cluster of multivendor workstations.
