Practical application of formal methods requires more than advanced technology and tools; it requires an appropriate methodology. A verification methodology for data-path-dominated hardware combines model checking and theorem proving in a customizable framework. This methodology has been effective in large-scale industrial trials, including verification of an IEEE-compliant floating-point adder.
