Abstract

The concept of prime faults is introduced for the study of multiple fault diagnosis in combinational logic networks. It is shown that every multiple fault in a network can be represented by a structurally equivalent fault with prime faults as its only components. Functional and structural masking and covering relations among faults are defined. These relations can be exploited to greatly simplify multiple fault analysis and their test generation. We present an efficient algorithm that generates a multiple fault detection test set and identifies redundancies. Suggestions for designing networks to yield a minimum number of tests in the multiple fault detection test set are also included.

组合网络中的多故障诊断
为了研究组合逻辑网络中的多故障诊断问题,引入了主故障的概念。结果表明,网络中的每一个多故障都可以用一个结构等效的故障来表示,而主故障是其唯一的组成部分。定义了断层之间的功能和结构掩蔽和覆盖关系。利用这些关系可以大大简化多故障分析及其测试生成。我们提出了一种有效的算法来生成多故障检测测试集并识别冗余。本文还提出了在多故障检测测试集中产生最少测试次数的网络设计建议。
