中文摘要：
多跳变（MT）故障模型是一种有效的总线串扰故障模型,可以测试由电容和电感导致的串扰故障,但是MT的原始测试集存在严重的向量冗余.通过分析MT原始测试集向量冗余的3类情况,利用欧拉回路对测试向量进行组合优化,得到MT精简测试集,同时不损失MT故障覆盖率;还设计了MT故障模型的软件自测试程序来实施MT精简测试集,用于实速在线检测串扰故障,而不需要使用高速测试仪.实验结果表明,采用MT精简测试集可以有效地减少总线串扰测试的时间和向量存储开销.
英文摘要：
Multiple transition （MT） fault model is an effective fault model for both the capacitive and inductive coupling induced faults on bus. But the previously generated test set based on MT fault model tends to be redundant. In this paper, cases of the pattern redundancy of the MT test set are analyzed and classified into three types. Euler loop is then used to compact MT test patterns and get optimized MT compacted set without losing fault coverage. Then, a self-testing program for MT fault model is developed to apply the MT compacted set to on-line at-speed detecting of crosstalk-induced faults. Experimental results on the system of network card show that the test time and pattern storage overhead can be significantly reduced with the MT compacted test set.
