为提高数字电路故障诊断的效率
针对传统故障压缩算法的压缩率不高、计算复杂的问题
提出新的解决方法.与传统方法不同
该方法通过对故障检测函数的分析得出决定电路中特殊结构的故障关系规律.首先利用电路蕴涵信息推导出电路中节点与其支配点之间故障等价与支配关系
随后总结出具有重汇聚扇出源与其分支之间故障关系的规律
故障关系与扇出分支的反向奇偶特性密切相关
并且受重汇聚节点逻辑功能影响
进而发展为运用电路蕴涵及拓扑信息来压缩故障的方法.基于ISCAS85 Benchmark 的实验结果表明
该方法可有效判断出电路中可测故障的等价与支配关系
并且实现简单
计算量较小.
To improve the efficiency of fault diagnosis in digital circuits
a novel method is proposed to solve inefficient compacting and complex computing in the traditional algorithms. Compared with traditional method
the rules that determine fault relations in special structure are summarized by analyzing fault detect function. The equivalence and dominance fault between node and its dominator with implications are identified
then the fault equivalence and dominance rule for reconvergent fan-out stem and branches is also found out
which is not only depended on topological structure in circuit
namely
inversion parity of branches
but also influenced by logic function of reconvergent point. Moreover
the fault collapsing method using implication and topological information is presented. The experimental results based on ISCAS85 benchmark show that this method enables to identify equivalence and dominance fault in circuit effectively with a slight computation task.
