Abstract
本文介绍如何到处已有工程的管脚分配为tcl文档和使用Tcl文档来分配管脚
Introduction
FPGA芯片的引脚很多，如果手工分配，工作量很大，且容易出错。应该采用自动分配引脚的方法。
具体做法如下：
1 打开一个已经分配好引脚的工程，应该选择使用引脚比较多的工程。
2 点击Assignments 菜单下的Pins 菜单项， 打开引脚分配界面， 点击File菜单下的Export菜单项，打开引脚导出对话框，
选择导出文件类型为Tcl
3 在一个新的工程， 若要分配引脚， 点击View菜单下Utility Windows 的Tcl Console,
在Quartus 主界面的右下方，出现Tcl Console
4 将第二步生成的Tcl文件用记事本打开，选择全部内容复制， 在Quartus的Tcl
Console窗口粘贴， 并按回车键结束Tcl 命令。
5 点击Assignments 菜单下的Pins 菜单项，
打开引脚分配界面，可以见到已经分配了引脚。在工程中需要使用同样的I/O端口名称
以下为某工程的tcl文档，当然可以针对自己的工程编辑该文档
