According to high development of electronic technology, especially widely used of large scale integrated circuit, how to diagnosis faults in circuit by modern diagnosis technology is more and more important. Its working lifecycle is expanding from system design to maintain and update process. Any signal fault in any unit may cause circuit partly lose efficacy or the whole equipment become invalid. Therefore, this paper designed a new large-scale analog circuit fault diagnosis methods based on wavelet analyze, present the method to locate sub circuit and how to extract fault characteristics by wavelet analyze.
