Abstract
The paper proposes an automated approach with a formal basis designed for checking correspondence between an RTL implementation of a microprocessor and a description of its instruction set architecture (ISA). The goals of the approach are to find bugs not discovered by functional verification, to minimize user intervention in the verification process, and to provide a developer with practical results within a short period of time. The main idea is to use bounded model checking to check that the output produced by automatically derived RTL and ISA models of a given processor are the same for each instruction and each possible input. Although the approach does not provide full formal verification, experiments with the approach confirm that due to a different way it explores the state space of the design under test, it can find bugs not found by functional verification, and is thus a useful complement to functional verification.
