Packet-based input test data compression techniques

This paper presents a test input data compression technique, which can be used to reduce input test data volume, test time, and the number of required tester channels. The technique is based on grouping data packets and applying various binary encoding techniques, such as Huffman codes and Golomb-Rice codes. Experiments on actual industrial designs and benchmark circuits show an input vector data reduction ranging from 17/spl times/ to 70/spl times/.
