Abstract: Fault knowledge acquisition (FKA) is the bottleneck problem of circuit fault diagnosis based on knowledge, which seriously hinders the development of electrical equipment intelligent diagnosis system (IDS). The method to acquire fault knowledge based on simulation was proposed, which introduced how to establish fault-mode simulation model of analog-digital circuit components. By taking FMECA as simulation objective, the times of fault injection are effectively reduced. The establishment of simulation model library decreases the difficulty to program simulation files. The effect of this fault model is validated through an analog-digital mixed circuit.
