Abstract

Pspice engine which possesses powerful modeling and simulation functions is widely used to analog circuit simulation, while can not be provided with fault simulation function. This paper addresses the problem of how to performance analog circuit fault simulation simulate by calling Pspice engine. Firstly, the principle of the fault simulation was introduced. Under the supervision of the controller, the system carries out fault injection automatically into the target circuit, calls kernel spice3f5 simulation engine and realizes analog circuit fault simulation. Secondly, after analyzing the typical failure mode of the components and the way to trigger fault, two methods of the substitution method and the equivalent circuit method are used to build the fault model libraries which conform to the simulator. At last, an experiment is designed to validate the validity and practicability of the proposed method, proving that the method can reduce the computational complexity and improve the simulation speed and the degree of fault isolation.
