This paper present a hybrid test vector compression method reducing the testing time and test data volume size of SOC. Higher circuit densities in system-on-chip (SOC) designs have led to drastic increase in test data volume size. Today the silicon densities increase day by day, so it become very difficultly to test SOC, because it need the large test pattern. The method consists of two steps: Burrow wheeler transform (BWT) and pattern overlapping method. BWT is a block sorting lossless and reversible data transform. It improves the efficiency of text compression algorithm. The hybrid based compression scheme provides the high compression ratio and fast testing time. The major contributions of this paper are as follows: 1) it develops an efficient pattern overlapping technique for test data in order to create maximum matching patterns. 2) it proposes a test compression technique using efficient pattern overlapping method to significantly reduce the testing time and memory requirements of SOC.
