摘要
针对目前数字电路桥接故障诊断效率低的问题,提出了一种基于微分故障模拟算法的数字电路的桥接故障诊断方法,用VHDL语言对电路模型进行了重新建模,利用单固定故障的信息来诊断桥接故障,并对ISCAS85平台下的一些电路进行了模拟,结果表明该方法简单、高效,特别适合于数字电路的故障诊断,对于提升我国数字电路可靠性具有重要的理论意义与实际推广应用价值。
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.
