[ModelSim] how to know the currently used modelsim.ini? How to report its location?

Type 'where'.

For example, I use a Modelsim Tcl script to setup the path to modelsim.ini based on the tool version. If I type 'where' in Modelsim-ASE for Quartus II 15.0, this is the output

--- Quote Start ---

Modelsim> where

# Current directory is: C:/software/altera/15.0

# Project is: c:/build/modelsim/v10.3d_ase/modelsim.ini

#

--- Quote End ---

Note how the modelsim.ini path is to a location in my build area, in a folder specific to that version of Modelsim-ASE.

This allows me to have multiple versions of Modelsim-ASE and Modelsim-SE installed.

Cheers,

Dave
