Today's competitive market demands high quality levels for electronic devices including state-of-the-art microprocessors. Unfortunately, the full-custom design methodology and performance constraints of the Alpha 21164, a deep sub-micron, superscalar microprocessor, precluded brute force use of design-for-test (DFT) techniques such as full-scan insertion and automated test pattern generation. In addition, scan testing alone cannot guarantee the desired quality level for microprocessors in this genre. As a result, functional tests play a key role in achieving the quality goals of the Alpha 21164.
