摘　　要：由于专业知识要求高以及工作量大等问题,故障仿真技术在模拟电路故障知识获取过程中一直作为一种辅助手段使用。在总结通过故障仿真获取故障知识的一般过程的基础上,提出完全基于仿真的模拟电路故障知识获取自动化方法,该方法实质上是通过计算机用穷举法自动对所有可能故障进行仿真获取故障知识。讨论该方法面临的问题以及为解决问题采用的4个策略。实验结果证实新方法可行性。Because of the limitations of high dependence on experience and hard task, etc., the fault simulation is just an assistant technique in analog circuit fault knowledge acquisition. Based on summarizing the general procedure of knowledge acquisition by fault simulation, a method was proposed, which acquired the analog circuit fault knowledge by simulating all possible faults automatically in computer. This method fully bases on simulation. The problems this method faces and the four necessary strategies for solving them were analyzed. The result of experiment proves the feasibility of new method.
