摘要
在内建自测试中 ,针对随机向量测试 ,本文提出了一种通过输出信号分组压缩来减少多输入特征寄存器 MISR的硬件开销的方法。该方法是在分析输出信号之间相关性的基础上 ,根据给定的 MISR阶数构造具有最小相关度的输出信号集合组 ,以此来减少输出信号分组压缩时的故障覆盖率损失。
In built-in self-test according to the random test the paper presents a method of grouping compression of output signals for reducing the hardware overhead of MISR.Based on the analysis of relevance weight among output signals the method constructs the set group of output signals with minimum relevance weight to reduce the loss of fault coverage using grouping compression,and the method needs no auxiliary circuity.
