摘要
本文提出了一种新的故障定位算法。该算法将静态电流诊断方法与基于小波分析的动态电流诊断方法相结合,并通过模式识别进行决策,实现可精确到电路元件的CMOS集成电路多故障定位。经过仿真实验证明,该算法的可行性和有效性。
A novel algorithm for fault localization using quiescent current and transient current is presented. The algorithm is realized by combining quiescent current diagnosis and transient current diagnosis based on wavelet transform. After classification of the potential faults with pattern recognition, the actual faults can be located accurately and effectively. Simulation experiments prove that the proposed algorithm is feasible and effective.
