Hi Punnet,
SS has already replied you. I just wanted to add few more, which
will definitely help to understand about changing radix during
simulation time.
Questa has a vey simple .do file command called "radix" to examine/
change the radix in run time.
If you simply put radix in your .do file, it will return radix
which is set by deafult (I think, by default It is symobolic). Now,
whenever you want to change the radix, simply put either of "radix
hex", "radix binary" or "radix octal" as per your requirement.
Thanks and Regards,
