Reconfigurable broadcast scan compression using relaxation-based test vector decomposition

A Power Efficient Test Data Compression Method on Count Compatible PRL Coding

“…These approaches have been improved using the recon¯guration in which the tester channels are used to drive the SCS. 5 Code-based schemes have been widely applied, which transfers the speci¯ed bitstrings in test data into a segment of codeword. The Hu®man coding 6 provides the shortest average codeword length.…”

Test data compression using alternating variable run-length code

“…Test data volume and power reduction can be achieved by utilizing a built-in self-test (BIST) [5][6][7], test compaction [8,9] and test compression techniques [3,4,[10][11][12][13][14][15][16][17][18][19][20][21][22]. However, BIST requires a longer test application time, and it is extensively used for memory testing but is not common for logic testing [17].…”
