Abstract :
Storage/logic arrays (SLAs) represent an efficient structured logic array approach to the design of VLSI sequential logic circuits with low area overhead. The authors present an approach to testable SLA design which provides for detection of all missing device and stuck-at faults in addition to several broader classes of faults, including bridging and open line faults. Testable designs and test generation algorithms are given for both NMOS and static CMOS SLAs. An SLA augmented for testability is presented. The hardware costs are analyzed and the testing strategy is presented. The test sets are analyzed and are shown to provide high fault coverage over a large class of faults.<>
