Abstract: An apparatus for and method of automatically generating, transmitting, receiving, and verifying test request messages within a large scale resource sharing computer system. In the preferred mode, the testing technique is applied to a memory resource having up to four requester ports. The test messages are simultaneously but randomly generated within each of the requester ports. These test messages are transferred to the memory resource. The responses from the memory resource are automatically verified within each of the receiving requester ports.

Abstract: A test driver for use in validating an electronic circuit design is disclosed. The test driver not only provides stimulus and verifies the response of a circuit design, but also responds appropriately to requests provided by the circuit design. The test driver may also modify a selected portion of a data element before returning the data element to the circuit design. Under some test conditions, this helps verify that the test driver did in fact gain access to a data element during a particular test case.
