本文主要介绍了一个通用多目标的单片机/嵌入式系统模拟软件的研究与开发过程，该软件可以以较高的精度（时序上可精确到机器周期，信号上可精确到引脚）模拟各种类型的嵌入式硬件（包括MCU、CPU以及各种外设），从而在通用计算机系统（比如PC）上精确地模拟出一个嵌入式系统环境，嵌入式操作系统和应用软件可以不加修改地在这个环境中运行和调试，并可得到和在真实硬件上完全相同的结果。-This paper introduces a generic multi-objective microcontroller/embedded systems research and development of process simulation software, the software can be relatively high accuracy (timing can be accurate to machine cycle, the signal can be accurate to pin) analog various types of embedded hardware (including MCU, CPU and various peripherals), which in general computer systems (eg PC) on the precision of a simulation environment for embedded systems, embedded operating system and application software can not modify in this run and debug environment, and may be and in the real hardware exactly the same results.
