Abstract
An interface system for testing and verifying the design of an ASIC at different levels of abstraction, wherein the ASIC includes a logic entity and a processor entity. The system of the present invention is embodied as software which executes within a computer system. The software, when executed by the computer system, causes the computer system to implement a model of the ASIC, a simulator, and a test interface. The model of the ASIC is embodied in HDL (Hardware Description Language) and includes a logic entity and a processor entity. The simulator is adapted to test the model. The test interface interfaces the model with the simulator. The test interface includes a simulator portion and a model portion. The simulator portion is coupled to the simulator. The model portion is embodied in HDL and is coupled to both the logic entity and the processor entity. The model portion and the simulator portion are coupled to exchange information. The model portion is operable to obtain register status information of the processor entity and provide the register status information to the simulator via the simulator portion such that the register status is observable by the simulator as the model is simulated at different of levels of abstraction.
