| Abstract(in English) | BIST-aided scan test (BAST) has been proposed as one of the techniques that enhances scan-based BIST. The BAST architecture can achieve high fault coverage by applying ATPG patterns to a circuit through the inverter block that flips some bits in random pattern generated by LFSR. In this paper, we propose a test pattern generation method for BAST that controls scan shift and applies partial reset of inverter code to reduce test data. The proposed method can reduce the number of BAST codes required inverter code by partial reset and generate effective LFSR patterns by controlling scanshift. We also show the effectiveness of our method by the experimental results for ISCAS 89 and ITC99 benchmark circuits. |
