modelsim 2020.4 安装

1. If you have installed Questasim 10.6c before and successfully cracked it, you can skip steps 2, 3, 4, and 5 and go directly to step 6.
2. Create a flexlm folder in the root directory of the C drive.
3. Copy MentorKG.exe and patch64_dll.bat to C:\modeltech_10.5\win64.
4. Run patch64_dll.bat, select Save As... after the pop-up dialog box, save as C:\flexlm\LICENSE.TXT
5. Add LM_LICENSE_FILE = C:\flexlm\LICENSE.TXT to the environment variable.
6. Overwrite the two files with the same name under C:\questasim64_2020.1\win64 with the mgcld64.exe and mgls64.dll files in the win64 folder.
7. Run the program, you can open it normally, and the cracking is complete.
 
Note: The new version of the program can no longer use the -novopt option vsim command, just replace -novopt with -voptargs=+acc, and there will be no situations where the signal is optimized and cannot be displayed.
 
Good luck everyone! ! !
