根据ModelSim提供的命令或者Tcl/Tk语言的语法，将仿真Cmd流程的仿真命令依次编写到扩展名为“do”的宏文件中，然后直接执行这个DO文件，就可以完成整个仿真流程-According to the order provides ModelSim or Tcl/Tk language syntax, the simulation process simulation Cmd command followed by the preparation of the extension " do"　macro file, and then direct the implementation of the DO file, you can complete the entire simulation process
