  • Hardware and software co-simulation including simulating the cache of a target processor
    Publication number: 20020019969
    Abstract: A co-simulation design system that runs on a host computer system is described that includes a hardware simulator and a processor simulator coupled via an interface mechanism. The execution of a user program on a target processor that includes a cache is simulated by executing an analyzed version of the user program on the host computer system. The analysis adds timing information to the user program so that the processor simulator provides accurate timing information whenever the processor simulator interacts with the hardware simulator. The analysis also adds hooks to the user program such that executing the analyzed user program on the host computer system invokes a cache simulator that simulates operation of the cache.
