Enhanced Compression Code for SOC Test Data Volume Reduction
Journal Title: International Journal of Computational Engineering and Management IJCEM - Year 2015, Vol 18, Issue 3
Abstract
Test data reduction is an important issue for the system-on-a-chip designs. A number of coding techniques have been developed in the past to compress the test data to achieve the best compression. In this paper we have merged two run length based codes i.e. Golomb code and AVR code to develop a new code called integrated compression code (ICC). The enhanced compression code (ECC) compresses the data achieved after compression form ICC by 9C coding technique to enhance the compression ratio further. We have also compared the proposed compression technique with previously developed compression codes. We have applied column bit stuffing, column bit stuffing with difference vector and ZERO filling for unspecified bits of the test set to reduce the average and peak power. These were calculated using WTM. Four ISCAS’89 benchmark test sets have been used to prove the effectiveness of the proposed ECC.
