A Novel Approach for Implementing Microarchitectural Verification Plans in Processor Designs

The ever-growing microarchitecture complexity of processors creates a widening gap between the verification plan and the test generation technologies used in its implementation. This gap impacts the cost and quality of the verification process. To overcome this, we introduce a novel test generation platform for processor verification. This approach is based on a scenario description language that is close to the microarchitecture verification plan, and uses new test generation algorithms and a microarchitectural model to support this higher level of abstraction. Initial results on a high end industrial design show our approach reduces the effort of implementing a microarchitectural verification plan and improves the quality of verification.
