Vivado与Modelsim联合仿真
笔者在学习FPGA过程中遇到了如何使用Vivado和Modelsim进行联合仿真的问题，特此记录。
首先确定版本
笔者Vivado用的是2018.3版本，先是随便下了个Modelsim10.1c 的版本，到编译库文件时报错了，后来发现是俩款软件的版本不匹配。所以大家在进行联合仿真之前先核对两个软件的版本是否对应，不用到最后再卸载重装。
具体的版本对应情况放到文档末尾，大家可翻到文末查看。
笔者用的是Vivado2018.3，查询的对应的Modelsim版本为10.6c。
Modelsim破解
准备Modelsim10.6c的安装包
下载链接
步骤如下：
(1)、安装软件，注意安装路径中不要出现中文或空格，安装过程中一直点击YES即可。
(2)、把crack.bat、MentorKG.exe一起拷贝到modelsim安装目录的win64文件夹下，例如D:\modelsim_dlx64_10.6c\win64pe
(3)、双击crack.bat，若出现下图所示问题，则将mgls64.dll重命名为mgls.dll再次重新运行crack.bat即可。
(4)、将生成的LICENSE.TXT放在modelsim的安装路径下，如D:\modelsim_dlx64_10.6c，若前面修改了mgls64.dll文件的名称，则生成完LICENSE文件后应当把名字改回去。
(5)、新建环境变量MGLS_LICENSE_FILE，变量值为LICENSE放置的路径，如D:\modelsim_dlx64_10.6c\LICENSE.TXT。在win10中，右键此电脑->属性->高级系统设置->环境变量，进行环境变量的添加。
(6)、打开Modelsim软件，安装破解结束。
联合仿真
(1)、打开任意一个vivado工程，再按下图所示点击编译Xilinx的仿真库。
注意：Simulator选Modelsim Simulator，编译库Compiled library location放入新建的文件夹D:\Xilinx\Xlib中(可自己指定)，Simulator executable path选择modelsim安装路径下的win64pe。注意Compile Xilinx IP选项不勾选。
编译结果从Vivado中的Tcl Console中可知，无Errors，芜湖起飞！
(2)查看编译库Compiled library location路径下，应该出现modelsim.ini文件。
我们将其设置为用户的全局变量，这样下次就不需要再编译库文件了，步骤如下图所示：
(3)、设置第三方仿真软件的安装路径与编译库的路径，具体步骤如下图所示
(4)、全部准备就绪后，点击Run Simulation中的Run Behavioral Simulation。
自动弹出Modelsim，并显示波形，游戏结束。
