| Abstract: | Facing on the difficulties appearing in fault diagnosis and maintenance of analog PCB, a new diagnosis method based on fauh dictionary is introduced. This tool integrates a number of critical technologies, such as graphical circuit model inputting, component fauhs auto-inserting, ACs frequencyauto--selecting, and test points optimized selecting; based on circuit auto emulation and data analysis, it realizes the auto-generating of fauh dictionary applying to circuit diagnosis. The test shows that the tool will avoid the problems existed in traditional diagnosis process depending on artificial analysis, improve the diagnostic efficiency greatly and realize auto test of analog circuit. |
