摘要
Abstract
To solve the catastrophic fault of analog circuits,this paper proposes a fast location method based on Mahalanobis distance.Firstly,a simulation of circuit and fault modeling is made in PSPICE for the Continuous-Time Sate-Variable Filter in the ITC＇97 Analog and Mixed-Signal Benchmark Circuits.Secondly,simulation data of both fault-free and faulty circuit is imported into Matlab using PSPICE and Matlab software data interface technology.Then,wavelet transform and Mahalanobis distance calculation of the simulation data is done in Matlab.Finally,the faulty component would be detected based on the Mahalanobis distances of both fault-free and faulty circuits.Tests show that this method with quick positioning ability has the advantage of simplicity and small online computational amount.关键词
