The Application of BIST-Aided Scan Test for Real Chips


It is common to use ATPG of scan-based design for high fault coverage in LSI testing. However, significant increase in test cost is caused in accordance with increasing design complexity. We proposed a new method, BIST-aided scan test (BAST), to reduce test cost in 2OO3 (Hiraide). Since then, we applied this method for about 200 chips, and the result is… (More)
