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

[Altera_Forum]

Hi All, 

 How can I know what modelsim.ini is currently used by Modelsim?  How can I report a path (location) to the modelsim.ini from the Transcript window of Modelsim?  Thank you!

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

Here is an output from the where command in my ModelSim: 

%> where  # Current directory is: C:\QUESTA_PROJECTS # Project is: C:/QUESTA_PROJECTS/USBIF.mpf #  So, the modelsim.ini location is not reported, just a location of the *.mpf file and the current directory

*.mpf is a Modelsim Project File. That is an alternative file to modelsim.ini. I have never found it to be particularly useful, so have stuck with the modelsim.ini file. 

 Read the Modelsim documentation for more details on the differences between the two files. I can't recall what I did not like about *.mpf files, it could be that I was just resistant to change :)  Cheers, Dave

OK, lets say I started the ModelSim with some modelsim.ini, but now I want to switch to another project, which should use another modelsim.ini.  

 So, how can I switch between the different modelsim.ini files? Can I source the modelsim.ini (like another tcl file)?
