Test Pattern Generation for Detection of Sutck-Open Faults in BiCMOS Circuits

BiCMOS circuit consist of CMOS part which constructs logic function, and bipolar part which drives output load. In BiCMOS circuits, transistor stuck-open faults exhibit delay faults in addition to sequential behavior. In this paper, proposes a method for efficiently generating test pattern which detect stuck-open in BiCMOS circuits. In proposed method, BiCMOS circuit is divided into pull-up part and pull-down part, using structural property of BiCMOS circuit, and we generate test pattern using set theory for efficiently detecting faults which occured each divided blocks.
