Preference variables located in TCL files
ModelSim Xilinx User’s Manual ModelSim Variables A-281
The By Name page is a graphic representation of the "Preference variable arrays"
(A-272) located in the modelsim.tcl preference file.
The changes you make in the Preferences dialog box are temporary for the current
simulation. Your changes can be saved as permanent defaults by using Main >
Options > Save Preferences. The new settings are saved to the current directory
in the modelsim.tcl file by default. You may choose a different name for the TCL
file if you wish.
See "Preference variable arrays"
(A-272) for a list of the standard preference
variables to be found in the modelsim.tcl file.
Directly editing preference files
You can also modify variables by editing a preference file with any text editor.
Make sure the file is saved as plain text. The ModelSim notepad
(CR-70) provides
a convenient way to edit a text file. At the ModelSim prompt type:
notepad <preference file path>
To edit the file once opened, change the read-only status with the Edit > read only
menu selection.
Note: Case is significant in variable names, be careful when you edit variables!
More preferences
Additional compiler and simulator preferences may be set in the modelsim.ini and
MPF files, see "Preference variables located in INI and MPF files"
(A-259).
