METHOD AND APPARATUS FOR SUPPORTING VERIFICATION, AND COMPUTER PRODUCT

In a verification supporting apparatus, when an obtaining unit obtains a verification scenario, a substituting unit substitutes an undefined value for a variable value in the verification scenario. A first executing unit executes a logic simulation using an input pattern. From a result of the logic simulation, a determining unit generates code-coverage upper-limit information. A setting unit sets input patterns by giving an arbitrary logic value to the variable value. A second executing unit executes a logic simulation using the input patterns set. A generating unit generates code coverage from the input patterns set. A calculating unit calculates a level of achievement of the code coverage with respect to the code-coverage upper-limit information.
