Hi, I used to simulate the simple schematic. The compile worked fine.
But when I ran University program/vwf, There was an error Warning: (vlib-34) Library already exists at "work".
I tried to reinstall it. but wasn't work.
What can I do?

Hi, I don't think the warning message will impact the simulation but you should check for any error message that followed after that.
May I know what is not working in your project?

I ran a very simple OR schematic. Compilation was good. The above error occurred during the simulation process, but I do not know how to fix it.

It seems that is an error.
Error: ortest.vt(60): near ",": syntax error, unexpected ','
Could you check the ortest.vt file line 60, is there something missing?
I am not sure if there could be a bug in previous Quartus version, could you try to install the latest Quartus version for Cyclone IV GX device and see if the issue persists? Lite version 19.1 or Standard version 20.1.
