automatic test bench generation for simulation-based validation
In current design practice synthesis tools play a key role, letting designers to concentrate on the specification of the system being designed by carrying out repetitive tasks such as architecture synthesis and technology mapping. However, in the new design flow, validation still remains a challenge: while new technologies based on formal verification are only marginally accepted for large designs, standard techniques based on simulation are beginning to fall behind the increased system complexity. This paper proposes an approach to simulation-based validation, in which an evolutionary algorithm computes useful input sequences to be included in the test bench. The feasibility of the proposed approach is assessed with a preliminary implementation of the proposed algorithm.
