This paper describes the detailed study and analysis of Golumb codes used for the test vector compression in VLSI testing. The Golumb Codes are widely used for lossless Data compression due to its simpler encoding and Decoding methods. Furthermore, a comparative study of various compression techniques is also presented in this paper. This paper also give out an idea about the design of Golumb Encoder and Decoder using VHDL for the test vectors thus achieving a good height of compression ratio. The developed algorithm can be verified using the Modelsim 6.3f, Xilinx 9.2i and ALTERA Quartus II software.
