| Abstract: | Facing on the low efficiency in bridging fault diagnosis of digital circuits, a bridging fault diagnosis method in digital circuits based on differential simulation algorism has been presented to rebuild the model of circuit components. It use the information of stuck-at fault to diagnose bridging fault. It has been tested by ISCAS'85 standard circuits. The result indicated this method has high efficiency, especially suit to digital circuits. It can help to improving the reliability of our country's digital circuits, and it is worthy of using abroad. |
