Index Terms:
This paper describes a functional verification methodology based on a system developed at the IBM Microelectronics Embedded PowerPC Design Center, in order to improve the coverage and convergence of random test generators in general and model-based random test generators in particular. It outlines specific tasks and methods devised for qualifying the test generators at various stages of the functional verification process to ensure the integrity of generated tests. It describes methods for calibrating the test generation process to improve functional coverage. In addition, it outlines a strategy for improved management and control of the test generation for faster convergence across corner cases, complex scenarios, and deep interdependencies. The described methodology and its associated verification platform are deployed at the IBM Embedded PowerPC Design Center in Research Triangle Park, North Carolina and has been used in the verification of 4XX and 4XXFPU family of PowerPC Processors.
