片上系统设计中软硬件协同验证方法的研究

A Hardware-Software Co-verification Method for SOC Design

讨论一种面向片上系统(SOC)设计的基于指令集模拟器和硬件模拟器的软硬件协同验证方法。该方法能够在SOC设计的早期对整个系统功能进行验证,能够为设计者提供一个纯虚拟的软硬件协同验证环境。重点讨论协同模拟过程中软硬件交互事件的产生和处理方法,以及软硬件模拟器之间的同步和优化方法,并且给出了事件驱动硬件模拟器的协同模拟控制算法。最后给出了一个基于ARM7TDMI的设计验证实例。

This paper presents a hardware-software co-verification method for SOC design, which is based on instruction set simulator and hardware simulator, and used to validate function of SOC in the early design phase. The generating and processing methods of interactive events between hardware and software simulator during co-simulation are discussed in detail. An algorithm of synchronizing between hardware and software simulator is presented, and to reduce the synchronization overhead, some optimizing methods are introduced. Finally, an co-verification example of a design based on ARM7TDMI is given.
