摘要: 提出了一种基于部分动态LFSR重新播种的改进方法,利用向量的部分相容原理来减少需要编码的确定位的个数,提高数据压缩率。并使用时钟测试来减少生成测试向量所需的时间。实验结果表明,与目前国际同类编码压缩方法相比,该方法提高了编码效率,节约了测试时间。

Abstract: A new LFSR reseeding methodology is proposed.In order to reduce the storement of the test data,the authors consider the partial consistent between the test vectors to reduce the special bits in the test vectors.It can reduce the time used to generate the test vectors by using the clock test.The results show the proposed method has more efficiency on encoding and reduce the test time.
