Abstract(in English) | In this paper we propose a new method of test data compression for multiple scan chain designs. The proposed method consists of two phases of data compression. In the first phase, ATPG test vectors applied to multiple scan chains are encoded to reduce the number of test input pins and thus reduce the test data volume. In the second phase, the encoded test vectors are compressed further using statistical encoding to reduce the length of the test sequences applied to each test pin. This reduces test loading time and test data volume. Experimental results for large ISCAS-89 benchmark circuits show that the proposed method reduced the test data volume to 21.5% on average. |
