Is there a way to change ModelSim's default radix in code or command line?

Hello, Without editing the modelsim.ini's line 'DefaultRadix = symbolic', is there a way I can specify a change to the default within my ***_tb.sv source file? How about in a .do script file? ...

    Thank you ShyanYewT,

    Unfortunately, the default does not carry when I move source files to a new folder and start a new Modelsim. I would have liked to have found a way to set it in my source testbench or .do file which contains the:

    vsim -t 1ps -L altera_ver -L lpm_ver .....

    However, going to the vsim in the command reference manual, I found:

    vsim -default_radix unsigned -t 1ps -L altera_ver -L lpm_ver .....

    for the vsim command. This is what I was looking for and I wonder why my .pdf viewer never did show this text of 'default_radix' when I did a search for 'radix'. For some reason, maybe the underscore, the - in front, or that it was a blue link, all the text search showed was a number of other 'radix' references throughout the documentation.

With the Modelsim GUI opened, you might change the radix following the steps below:

1. Select Simulate > Runtime options...
2. In Default Radix box, select your desired radix.


Hope it helps.
