Reduce the code for reset function

UVM

I am writing a function in scoreboard to check whether reset is working.
This is the code

function bit check(Packet obj);
  if(obj.a == 0&&
     obj.b == 0&&
     obj.c == 0&&
     obj.d == 0&&
     obj.e == 0)
    return 1;
  else
    return 0;
endfunction

Is there anyway to reduce this code by traversing through each content of obj and checking whether it’s 0, without individually checking each?

In reply to bachan21:

You could write

function bit check(Packet obj);
  if(obj.a ||
     obj.b ||
     obj.c }}
     obj.d ||
     obj.e )
    return 0;
  else
    return 1;
endfunction

Or if you are using the UVM’s field automation macros, you could pack all of the registered fields into an array and check that the array was all 0. However, that would be very inefficient.

You can encapsulate that specific function in the packet class and make it reusable by everyone. Then in the scoreboard it will mainly just a matter of calling it

I do not know hoa you are checking the functionality of your DUT. But you should have areference model which checks also the reset function. Then you do not need a specific check function.

Hi,

TB development is in initial days so we are making a basic environment to test DUT.
But my reset signal is not a part of sequence item. So I am detecting the reset action in monitor and sending it to scoreboard.
