DEBUGGING TECHNIQUES FOR A PROGRAMMABLE INTEGRATED CIRCUIT

摘要

Techniques for debugging a programmable integrated circuit are described. Embodiments include steps of initiating instruction-cache-misses in the integrated circuit using a remote computer executing a test program; substituting, during an instruction-cache-miss event, instructions in the application program with test instructions provided by the test program; and debugging the integrated circuit based on analysis of its responses to the test instructions. In exemplary applications, such techniques are used for debugging graphics processors of wireless communication system-on-chip devices, among other programmable integrated circuit devices.
