How can I undo something set in the global modelsim.ini?

I want to use OSVVM. Modelsim comes with an older version of OSVVM precompiled in a library called osvvm. This is set up in the global modelsim.ini file:

osvvm = $MODEL_TECH/../osvvm

I would like to be able to compile a later version of OSVVM. I still want to compile it into a library called osvvm, because that is where the OSVVM source code expects it to be.

I have got round this temporarily by just commenting out the above line in the global modelsim.ini. That works, but is not very sustainable: it will have to be done every time we install Modelsim (presumably).

So, is there some way of undoing this line in a local modelsim.ini file? That would be much more sustainable for me. Or, is there some other method that doesn't involve making a machine-specific change?

You can simply overwrite the global mapping in your local 'modelsim.ini'. This file is automatically loaded when you enter the directory (at least in the modelsim GUI).

Just make a local modelsim.ini in you project/simulation directory and fill it with:

[Library]
; load the global modelsim.ini
others = $MODEL_TECH/../modelsim.ini
; overwrite the existing mapping
osvvm = osvvm

(assuming your osvvm has been build in the directory osvvm in your project directory. Else just add the correct path.)

Almost every ModelSim program can load a private modelsim.ini with option -modelsim_ini. You can write your own modelsim INI file.

I suggest, to remove OSVVM from the global modelsim.ini and create a local modelsim.ini that references the existing global file. INI file syntax:

others = ../../modelsim.ini
