DESIGNING VLSI CIRCUITS FOR TESTABILITY

Approved for public release; distribution unlimited b-. 6:..i i- " " o;. _ '-. Preface The purpose of this study was to investigate methods of designing a circuit that would be highly testable when completed. This subject is of great interest to the government as well as private industry. The more testable a circuit is, the more time and money can be saved once a device is fabricated. It is for these reasons that I chose this topic. During this study, methods were examined to design testable circuits, and were implemented in a design of my own. Although not completely self-testing, the design * should give you a feeling for the difficulty of designing. such a circuit, and the ease of testing it. In would like to thank my faculty advisor, Lt Col Harol
