Abstract：Experiment statistic finds that the more number of data blocks of test vectors are compatible with the reference data
blocks, the smaller frequency of occurrence in the test data will be. On the contrary, the greater frequency will appear. According to
this law, this paper presents a test data compression algorithm with FDR code. The simulation experiment of ISCAS reference circuit
shows that the algorithm is better than another encoding mode in improving the compression ratio
