A Test Pattern Compaction Method Using SAT-Based Fault Grouping

抄録

This paper presents a test pattern compaction algorithm applicable for large scale circuits. The proposed methods formalizes the test pattern compaction problem as a problem finding minimum set of compatible fault groups. Also, an efficient algorithm checking compatibility of fault group is proposed. The experimental results show that the proposed algorithm achieves similar or better results against a couple of existing methods, especially for middle circuits.
