摘　　要：为了能够充分、快速验证USB 2.0主控器的功能,设计了一个软硬件协同仿真平台。其中,CPU模型部分采用一种高效的SystemC模型,而不使用基于指令集的复杂CPU模型。测试用例采用抽象层次更高的C语言编写,通过调用仿真平台对外提供的API完成激励生成与响应检查。结果表明,该方式能够有效降低对仿真资源的占用,减少仿真时间;同时使软件人员能在IP的硬件验证阶段就能完成软件的设计测试工作,缩短软硬件接口整合时间,加快开发进度。A SW/HW co-simulation platform was designed for the sufficient and rapid verification of USB2.0 master controller. In this platform, an efficient SystemC model is adopted for CPU model instead of the instruction set based complex CPU model. Test cases are writen with the higher abstraction level C language, which performs the stimulus generation and response checking through calling the API provided by the simulation platform. The simulation result shows that this method can effectively reduce the occupation of simulation resource and the simulation time. Meanwhile, it enables the software designers to fulfil the software debugging in hardware verification phase, so as to shorten the integration time of hardware and software interfaces, and speed up the development of the project.
