Hello,

I have a register

reg [31:0] test;
test=32'h12345678;
now when i display its content like
$display("Test=%0d",test);

what i get is Test =12345678;

But what i want it to print is Test =1234_5678

How can i accomplish this. any thoughts

You shouldn't get Test=12345678 with that decimal format specifier.

I haven't seen any way to automatically insert underscore separators.
Try this:
$display("Test=%x_%x", test[31:16], test[15:0]);

Hi I am sorry for the mistake.
yeah thats %0h.
the solution u have provided sounds good.
but actually when i have a queue like
bit [31:0] Q[16];
printing all the content will be to complex.
This is what i want,all the contents of this Q in hex format with underscore.
Any how thanks a lot for ur suggestion.
I try to figure out something.

SystemVerilog, I see!

How about a "for" loop?
Code: 
integer n;
...
for (n=0; n<16; n=n+1)
  $display("Q[%0d]=%x_%x", n, Q[n][31:16], Q[n][15:0]);
 


In SV, try using a foreach loop - you don't need to worry about the index length then!

However I don't believe you will get the "_" as you wished - perhaps you are used to Specman/E? That's a wonderful verification tool. Nothing can match that usability really.
