In this paper we give a new, systematic method to generate robust two-pattern test sets for transistor stuck-open (TSOP) faults in CMOS complex gates, using the Karnaugh map under a new approach. We consider CMOS complex gates consisting of transistor networks of either the sum of products (SP) or the products of sum (PS) forms. Following the proposed method, all the untestable TSOP faults are easily identified and the corresponding networks can be redesigned in order to become robustly testable. Our method is so simple and straightforward that it can be applied easily and quickly even in a manual processing way.
