  • Method and system for measuring and reporting test coverage of logic designs
    Patent number: 6718521
    Abstract: A method and system for easily and automatically determining the extent of test coverage for a design-under-test (DUT). Incremental test coverage information is gathered from the application of test cases to the DUT, and cumulative test coverage information is maintained. The incremental test coverage and cumulative test coverage information are fed into a correlation process, which correlates valid bus transactions automatically generated from a configuration file describing the DUT with the incremental and cumulative test coverage information. The correlation process determines which valid bus transactions have or have not been applied in testing the DUT.
