大型电子计算机的自动诊断,大多采用非功能诊断的故障测试定位技术(FLT).产生诊断资料、编制诊断程序均需极其浩繁的工作量,一般用计算机辅助解决,其核心是如何产生诊断测试码的方法.D 算法作为一个强有力的工具,被广泛地用于数字系统的故障诊断中.我们为解决某机自诊断和插件测试问题,希望见效快而选用了D 算法.由于整机逻辑设计的组合化,用于整机诊断只要组合线路的D 算法程序就够了,但对于插件测试则要 Large-scale computer automatic diagnosis, mostly non-functional diagnosis of fault test positioning technology (FLT). To generate diagnostic information, the preparation of diagnostic procedures require an extremely large workload, the general computer-aided solution, the core is how to generate diagnostic test patterns Method.D algorithm as a powerful tool is widely used in the digital system fault diagnosis.We have to solve a certain machine self-diagnosis and plug-in test problems, hoping to quickly and use the D algorithm.Because the whole logic design Combination, for the whole machine diagnosis as long as the combined line D algorithm program is enough, but for the plug-in test
