When loading MXE, the pref.tcl file is referenced for specific settings. Within the pref.tcl file, the modelsim.tcl file is referenced. You can set personal preferences within this .tcl file. Is a reference from the pref.tcl file to another .tcl file supported?
This feature is not supported in MXE. The pref.tcl file does not reference another .tcl file. However, pref.tcl and modelsim.tcl are independent of each other.
To work around this issue, you can append any personal preferences to the end of the pref.tcl file.
