Primace 软件是CME（京微雅格）公司的FPGA芯片开发专用软件。CME 的FPGA，如M5、M7等内嵌有8051 核心，因此可以与MCU联合在线仿真。虽然FPGA内部的程序不可控，无法一步步仿真，但由于MCU程序是可控的，因此可以利用MCU对FPGA发送命令，进而控制FPGA的运行与操作。因此，这一FPGA开发板也可以充当8051单片机开发板。
本文将介绍FPGA与keil联合仿真的相关设置，主要以简单的仿真案例为例。
在京微雅格官网上可以下载8051的专用驱动程序。安装完成后，在keil软件界面下拉菜单中可以找到对应的选项，选择后即可开始配置项目。
M5.h是M5系列FPGA开发板的8051驱动文件，包含所有相关寄存器的定义。文件内容如下：
