Feedback from higher-level verification to improve unit verification effectiveness

Abstract:

Embodiments of the invention are directed to a computer-implemented method of unit environment verification. The method includes monitoring, by a processor, a data stream between a first driver and a device under test (DUT) in a unit verification environment. The processor retrieves a transaction value from a database, wherein the transaction value was generated in a higher-level verification environment than the unit verification environment. The processor transmits the retrieved transaction value to the DUT. The processor compares a response from the DUT to the transmitted transaction value to an expected value. In response to the comparison indicating an error, the processor initiates a repair of the error at the unit verification environment.
