Intelligent Diagnosis Method for Intermittent Fault of Digital Circuit Based on Dynamic Power Current

In this paper, a novel method of intermittent fault diagnosis based on dynamic power current in digital circuit is proposed. The intermittent fault model in digital circuit is introduced. The influence of intermittent fault of different magnitudes and types on the dynamic power current of logic gate circuit is analyzed. Then, an intelligent diagnosis method of intermittent fault based on power current information is put forward, which has been verified on ISCAS85-C17 circuit. The test shows the feasibility of using dynamic power current for digital circuit intermittent fault diagnosis.
