3.Adding a Source File to a Project
Project-Add Source-Open->Adding Source Files dialog box
Association: All (选择Design View，如没配置，直接选All)
Library: work
->OK
4.Adding a Copy of a Source File to a Project
Project-Add a Copy of Source->Adding Source Files dialog box
6.Removing Files from a Project
UCF File Constraints
1.File-New(Ctrl+n)-Text File-OK
添加引脚定义
针对普通IO口：
NET “端口名词” LOC = 引脚编号 | IOSTANDARD = "电压";
对于时钟端口，还可定义时钟周期约束。即先在时钟网线clk附加一个TNM_NET约束，把clk驱动的所有元件定义为一个sys_clk_pin的分组，再用TIMESPEC约束定义时钟周期
注：UCF文件对大小写敏感，但对文件中的NET不区分大小写
