Re: Naming Values in ModelSim Wave with an Alias

Altera_Forum · ‎02-27-2016

Hi all,

I am wondering if there is a way to define a set of aliases for a models signal. Basically, I want to do the following:

1) I have a 5bit signal in the ModelSim waveform window called "opcode_r1"

2) The current number representation for the signal values is hex, so I will see values like: 0A, 1F, etc.

3) Is there a way I can define a set of aliases such that every time 0A shows up in that wave it displays ADD_IC instead of 0A?

As you can see its an opcode for a processor and I feel it would be much easier to see the actual opcode name rather than the raw hex value.

Thanks in advance!

You need to use the radix define TCL command in modelsim:


radix define opcode {
  5'h0A "ADD_IC" -color orange
}
etc.

I suggest reading the modelsim reference manual for a better definition.

This is what I was looking for!

With some more research after this, I found another good example on p67 of the following document:

Thanks Tricky!
