摘要
针对当前LFSR状态和种子的相关性,控制位在改变当前LFSR状态中相应位的值时,对该种子载入过程中需要改变的位进行控制,使得在生成载入种子测试向量时,不需要全部载入种子的全部位数值,从而使控制简单且种子的施加时间更短,实现测试数据压缩。通过实验证明,该方法能够有效地减少种子的存储空间和施加时间。
As the correlativity between current LFSR state and some seed, the proposed scheme changes the corresponding bits of current state of LFSR by control bits, and controls the bits that need to be changed in the seed loading process, and makes it unnecessary to load all values of the seed while loading seed to generate test vector. The scheme makes the controls simple and less time to load seeds for test data compression. The results of experiments have proved that this scheme has the advantages of reducing the storage and the time of seed applying.
