This paper presents a new test case generation technology, specifically targeted at verifying systems that include address translation mechanisms. The ever-growing demand for performance makes these mechanisms more complex, thereby increasing the risk of bugs and increasing the need for such technology. DeepTrans is a package that provides model-based test generation capabilities to verify translation mechanisms based on a modeling language. The modeling language includes constructs for describing the address translation process, commonly used translation resources, and architecture rules related to translation. Deep-Trans is currently used by two different IBM test generators.
