  • Patent number: 6687662
    Abstract: A system and method for automated design verification. A test bench stimulates a simulated design with test vectors. A coverage analysis tool monitors output data from the simulated design and identifies portions of the simulated design that remain to be tested. A test generator produces and sends test vectors to the test bench which exercise (i.e., test) the portions of the simulated design that the coverage analysis tool has indicated still remain untested. In the method, a first step executes a simulated design on a test bench. A second step interprets the simulated design as if this design were a state diagram composed of a set of basic blocks interconnected by transition arcs. A third step generates test vectors to exercise some of the basic blocks and transition arcs. A fourth step reports the basic blocks and transition arcs which have not been tested. A fifth step generates a new set of test vectors to exercise the as yet untested basic blocks and transition arcs.
