Analog/mixed signal fault diagnosis algorithm and tool review

Abstract

The development of fault diagnosis algorithms for digital systems has been intensively studied, reported and ultimately implemented in commercial-grade toolkits for testing applications. But the analog/mixed signal fault diagnosis problem, which encompasses the digital problem domain, is only now receiving much more attention. Computer-aided tools using algorithms that efficiently diagnose the cause of any unacceptable circuit behavior are now indispensable testing resources for electronics manufacturing and maintenance processes. This report is a description of several analog/mixed signal fault diagnosis algorithms and their implementation in computer-based tools.<>
