<p><b>Abstract</b>—A test pattern compression scheme for test data volume and application time reduction is proposed. While compression reduces test data volume, the increased number of internal scan chains due to an on-chip, fixed-rate decompressor reduces test application time proportionately. Through on-chip decompression, both the number of virtual scan chains visible to the ATE and the functionality of the ATE are retained intact. Complete fault coverage is guaranteed by constructing the decompression hardware deterministically through analysis of the test pattern set.</p>
