1. Install modelsim
After installing according to the normal installation method, usually the default path is C:\modeltech64_10.5.
Then copy the downloaded MentorKG.exe and patch_dll.bat files to the C:\modeltech64_10.4\win64 directory. And run C:\modeltech64_10.4\win64\patch_dll.bat as an administrator to generate LICENSE.TXT and copy it to the C:\modeltech64_10.5 directory.
Note that the read-only attribute of this file should be removed, otherwise the LICENSE file may not be generated, so change it back after generation.
Add the new environment variable MGLS_LICENSE_FILE in the environment variable as shown in the above figure, and the path points to the generated LICENSE file.
In addition, you need to remove the read-only attribute of C:\modeltech64_10.4\modelsim.ini, find and modify the variable VoptFlow = 0, save it, close it and change it back to read-only.
2. Quartus environment configuration
