  • Method and apparatus for verifying multiprocessing design in a unit simulation environment
    Patent number: 6567934
    Abstract: A method and apparatus for verification of designed logic in a processing unit (100) that performs multiprocessing functions is presented. Once the multiprocessing unit to be exercised as the device under test (350) is defined, an irritator (330) is constructed to provide the stimuli to the interface of the device under test (350) such that the device under test (350) is exercised. The irritator (330) receives instructions (314) as its input, where relevant instructions are converted to transactional stimulus that is applied to the device under test (350). The irritator (330) also monitors the interface of the device under test (350) to detect when multiprocessing operations executed by other processing units (340) included in the system (5) require a response. The response is produced via signal stimulus on the interface of the device under test (350) to which the irritator (330) is coupled.
