Description: The method of FDR codes compression based on compatible compression of multiple scan chains is presented chiefly in this paper. The test vectors are transferred 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. The test pattern was sorted to make the near mode have the least different bits, finally making use of the FDR code proceeds to compress for the second time.
Recently, reducing test application time and test data volume is a direction of effort in SoC design. This method can reduce the volume of test equipment and test times. Compared to the same type of the codes compression schemes, such as Golomb codes, statistical codes and compression using dictionary, the efficiency of the proposed scheme is better.
