“Drive Only” at speed functional testing is defined to be where the ATE drives input stimulus at native data rates and the results are accumulated or checked on die and the test result is accessed and checked by the Automatic Test Equipment, ATE, at a slow data rate. This paper summarizes the various “Drive Only” methods and associated DFT circuits that(More)
Silicon evaluation of scan patterns, targeting realistic bridges, for a high performance microprocessor is presented. The practicality of generating realistic bridge patterns is demonstrated. Silicon data, with and without functional fails, and in the presence of ndetect tests are presented. Data points to the value of and efficiency of bridge patterns.(More)
We present detailed experimental work involving a commercially available large scale shared memory MIMD paraliel computer having a software controlled cache coherence mechanism. The implementation of a scalable MIMD computer with hardwarecontrolled coherent shared hierarchical memory is indeed a formidable task and has yet to be effectively implemented. We(More)
