摘要
LFSR重播种的测试方法是一种内建自测试方法,存在3种重播种方法,分别是部分动态重播种方法,部分测试向量切分的重播和相容时钟的部分动态重播种方法,这3种方法在硬件开销、编码效率、测试时间方面均有所改进。
LFSR reseeding is a BIST testing method, there exists three testing methods based on LFSR reseeding, includes partial LFSR reseeding, syncopation of some test patterns LFSR reseeding and consistency clock test partial LFSR reseeding, these three testing methods can improve the testing hardware overhead, encoding efficiency and reduce testing times.
