On verifying a high-level design

An overview of design verification techniques is presented, and some of the current research in high-level design verification is described. Formal hardware description languages that are capable of adequately expressing the design specifications have been developed, but some time will be required before they can have the expressive power needed to be used in real applications. Simulation-based approaches are more useful in finding errors in designs than they are in proving the correctness of a certain design. Hybrid approaches that combine simulation with other formal design verification techniques are argued to be the most promising over the short term.
