Circuit Board Fault Diagnosis Algorithm And Fault Simulation Study

Fault is inevitable during the using of electron circuit. In practice, we think out of all kinds of methods to detect the fault existing in the electron circuit board. Then, we can supply reference for repair. This particle gives out some detection method, mainly about creation algorithm of detection vector and checking up the fault-cover rate of detection vector by the way of fault simulation.Creation algorithm of detection vector contains: Pseudo-exhaustive testing, D algorithm, fault dictionary algorithm.Fault simulation contains: parallel fault simulation and deductive fault simulation.In the base of research of creation algorithm of detection vector and fault simulation, we examined the fault-cover rate in our task using fault simulation. At the same time, we pointed out the problem in this application and amended fault simulation to fit our task.
