  • Apparatus and method for improving the efficiency and quality of functional verification
    Patent number: 5684946
    Abstract: A design verification system is provided which includes the ability to automatically correlate the response of a device under test to the input stimuli. The test system uses a pseudo-random exerciser to produce a set of test stimuli for application to a device under test. Once applied, the response of the device is recorded and an automatic correlation is performed using a chosen correlation engine. Once the correlation is complete a new set of stimuli is produced which results in improved test coverage for the device under test. The system is closed-loop and thus allows for iterative testing of a device under test.
