一种基于多扫描链相容

压缩的 Golomb 码的压缩方法。这种方法首先把原始测试集的测试向量转变成多扫

描链的形式，从而进行第一次压缩——相容压缩，接着对已经相容压缩过的测试

集进行重排，使其仍然保持原始测试集模式之间变化位较少的特性，并通过对测

试模式的优化排序使得相邻模式间具有最少的不同位，最后利用 Golomb 码的编码

方法进行第二次压缩。-The method of

Golomb codes compression based on compatible compression of multiple scan chains is

presented chiefly in this paper. The test vectors are transfered to the pattern of the

multiple scan chain and the compatible compression is implemented of first time. The

next, the test vectors are reset after the compatible compression, but the character that

there are a few different bits between test patterns of the test set is kept all the same.

Sort the test pattern to make the near mode have the at least different bits, finally

making use of the Golomb code proceeds to compress for the second time.
