摘　　要：利用LFSR与CSR结合,对产生的测试矢量进行过滤,使测试矢量数达到最少,从而降低测试过程中的测试功耗.以ISCSA85实验结果表明,该方案能够改善测试矢量之间的线性相关性,大量减少测试矢量之间的跳变,达到降低功耗的目的.重点介绍了改进型矢量产生器的方法和数据结果分析.This paper presents a new program about generating vectors on low - power test, which combine LFSR with CSR, to filtrate generated test vectors, and to less the number of testing vectors, thereby reduce the test power consumption in testing process. With ISCSA85 circuit experi- mental validation results shows that, the testing program which can improve the correlation between vectors, reduce significantly testing vectors between the transition, and attain the purpose to reduce power consumption. This article focuses on the method in improved vector generators and the data analysis of results.
