Verification managers engaged in complex IC development projects are under constant pressure to reduce the time and cost of verification, yet they lack the necessary resources. This white paper articulates how reusable verification components, and an underlying verification reuse methodology are essential elements to verification productivity gains. The issues that must be dealt with are delineated and the requirements of a complete verification reuse methodology are outlined. Verisity’s e Reuse Methodology (eRM) is used to exemplify many of the key concepts.
