Using macro as part of an array declaration's range

`define SOME_MACRO 2
`define SOMER_MACRO 0
`define OTHER_MACRO 3:0
bit [`SOME_MACRO:0] a;
bit [`OTHER_MACRO] c;

which of these work? and why?

i have used the declaration of a in my code, which was a signal of a module, and apparently verdi when selecting the signal recognizes the width as [0:0] instead of [2:0] though i am not sure whether that is a bug in verdi or how the compiler actually understands the line, considering `SOME_MACRO is 2 and not 0.

thanks and best regards

In reply to xning:

There is nothing wrong with the code shown here. If you display $left(a), it prints 2.
