Test Data Compression Based on GOLOMB Coding and Two-Value GOLOMB Coding

In this paper, we discuss test data compression and decompression method based on variable lengthGolomb codes and 2-V Golomb Codes for test data. The method is targeted to minimize the amount of testdata, which reduces the size of memory required in ATE for test data and also time required to transfer testdata to specific device on SOC. We completed MATLAB coding for both methods and applied test vectorsof some standard ISCAS benchmark circuits and compared results for same. Experimental results onISCAS benchmark circuits show that the compressed data produced by 2-V Golomb coding is better thanGolomb Coding method.
