Test Data Compression Based on Encoding Series and Alternation Sequences
Huaguo Liang · Jisuanji gongcheng · 2010
A new test data compression technique based on encoding series and alternation sequences is proposed.It is a variable-tovariable-length code based on encoding lengths of runs of 0 s and 1 s,as well as alternating bits in test sequences.The code word consists of prefix and tail,the scheme uses prefix to indicate the type of sequence.Due to its simple architecture,the additional hardware overhead that the decompression circuit requires is very small.Experimental results for the ISCAS'89 benchmark circuits show that this technique can efficiently compress test data.
