MicroTESK: An ADL-Based Reconfigurable Test Program Generator for Microprocessors

Abstract

Abstract-Test program generation plays a major role in functional verification of microprocessors. Due to tremendous growth in complexity of modern designs and rigid constraints on time to market, it becomes an increasingly difficult task. In spite of powerful test program generators available in the market, development of functional tests is still known to be the bottleneck of the microprocessor design cycle. The common problem is that it takes significant effort to reconfigure a test program generation tool for a new microprocessor design. The modelbased approach applied in the state-of-the-art tools, like GenesysPro, still does not provide enough flexibility since creating a microprocessor model is difficult and requires special knowledge and skills. The article suggests an approach to ease generator customization by using architecture specifications that describe the microprocessor behavior at a higher level. The approach is aimed at facilitating development of architecture models and, thus, minimizing time required to create functional tests. At the moment, we are working to implement a new generation of the test program generator MicroTESK that can be easily configured for various microprocessor architectures.
