摘要：介绍SoC(片上系统)软硬件协同验证中的软件仿真，给出验证uART(通用异步收发器)硬件接口的应用程序范例。利用GNU工具链开发SoC软硬件协同验证中的应用程序，并利用仿真器进行软件仿真，仿真结果正确。可以根据处理器的类型对GNU工具链进行配置，使开发流程适合所有GNu支持的处理器，方法具有一般性。根据开发者的具体需要，开发soc芯片的应用程序用于软硬件协同验证。-Abstract: SoC (system on chip) hardware and software co-verification of software simulation are given validation uART (Universal Asynchronous Receiver Transmitter) hardware interface, the application example. GNU tool chain developed by co-verification of SoC hardware and software applications, and use a software emulator simulation results are correct. According to the type of processor configuration on the GNU tool chain, the development process for all GNu supported processors, the method is general. According to the specific needs of developers, the development of applications for soc-chip hardware and software co-verification.
