摘　　要：本文讨论如何在基于Wishbone的软处理器平台上寻找用户元件故障。The use of an embedded processor in an FPGA offers many advantages. The ability to customize peripherals and available interfaces specifically for an application saves space, cost and development and testing time.However,issues can arise during development,such as the possibility that a design problem is present in the first implementation of a custom processor component. Debugging issues with the hardware design,the software or both can be more complicated in a single chip solution than in a multiple chip solution.Additionally,some problems are difficult to find unless the FPGA is being used in a realtime system.To effectively debug this complex hardware/software solution,a combination of processor and hardware debug techniques are needed.
