<p>The design verification of the cache controller for SPUR, a shared-memory multiprocessor, is reported. The strategy was to develop a random tester that would generate and verify the complex interactions between multiple processors in functional simulation. Replacing the CPU model, the tester generates memory references by random selection from a script of actions and checks. It was easy to develop and detect over half the bugs uncovered during functional simulation. A prototype SPUR multiprocessor system that runs the Sprite operating system is being used for experiments in parallel programming. Results to data are described.</p>
