Test Compression for Robust Testable Path Delay Fault Testing Using Interleaving and statistical coding

IEICE TRANSACTIONS ON INFORMATION AND SYSTEMS 2009年第2期E92D卷 269-282页

作者： Namba, Kazuteru Ito, Hideo Chiba Univ Grad Sch Adv Integrat Sci Chiba 2638522 Japan

This paper proposes a method providing efficient test compression. The proposed method is for robust testable path delay fault testing with scan design facilitating two-pattern testing. In the proposed method, test data are interleaved before test compression using statistical coding. This paper also presents test architecture for two-pattern testing using the proposed method. The proposed method is experimentally evaluated from several viewpoints such as compression rates, test application time and area overhead. For robust testable path delay fault testing on 11 out of 20 ISCAS89 benchmark circuits, the proposed method provides better compression rates than the existing methods such as Huffman coding, run-length coding, Golomb coding, frequency-directed run-length (FDR) coding and variable-length input Huffman coding (VIHC).

This paper proposes a method providing efficient test compression, for delay fault testing using enhanced scan design. In the proposed method, the initial anal transition. vectors of test data are interleaved before test compression using statistical coding. This paper also shows test architecture for delay fault testing using the proposed method. The proposed method is experimentally evaluated from the viewpoint of compression rates. For robust. testable path. delay fault testing on, 11 out of 23 ISCAS89 benchmark circuits, the combination of Huffman coding anal the proposed method provides higher compression rates than. Huffman. coding without the proposed method, run-length. coding, Golomb coding;frequency-directed run-length (FDR) coding and variable-length. input Huffman coding (VIHC).

Symbol ranking text compressors: Review and implementation

引用

SOFTWARE-PRACTICE & EXPERIENCE 1998年第5期28卷 547-559页

作者： Fenwick, P Univ Auckland Dept Comp Sci Auckland 1 New Zealand

Methods used by Shannon in 1951 when investigating the information content of English text are shown to lead to a class of 'symbol ranking' text compressors. Included in this class are some recent compressors which combine high performance with completely novel techniques. These are described under the aegis of the symbol ranking classification. Some new compressors, deliberately designed as symbol ranking, are then described. One of these has operated at over 1 Mbyte per second in software, and should be suitable for hardware implementation at tens of megabytes per second, or higher. (C) 1998 John Wiley & Sons, Ltd.
