资料介绍

针对混合信号电路故障检测难、检测准确率低的问题,采用神经网络与故障字典相结合的混合信号电路故障检测方法。运用Pspice对混合信号电路进行仿真,用蒙特卡罗算法对电路进行分析。提取电路中具有代表性的电流信息,建立正常状态下的故障字典。用Matlab进行神经网络的设计,通过训练、测试证明了该方法故障覆盖率可达到90%,准确率达到96%。

Currently, it's hard to detect faults and the detection accuracy is low in mixed-signal circuit. To solve these problems, the paper introduced a faults detection method, which combined neural network and fault-dictionary, for mixedsignal circuit. Fully emulating mixed-signal circuits hy Pspiee software and using Monte-Carlo method to analyze it. Then distilling the representative current-information of the circuit and establishing the fault-dictionary in the order. It used Matlab to design neural network, the experimental results from training and testing proved that coverage of the method can reach to 90% and accuracy 96%.
