Check() and extract() methods are not running

OVM

Hi,

I have a subclass of ovm_scoreboard and I’m trying to override the check() or extract() methods to do something at the end of simulation (run phase). Just to test it out, I put a print statement in check() and search for it in my log file, but for some reason, it looks like the method is never executed.

My code is something like this:

class my_sb extends ovm_scoreboard;
`ovm_component_utils(my_sb)

function new();
this.enable_stop_interrupt = 1; // is this necessary?
endfunction : new

function check();
$display(“end of test”);
endfunction : check
endclass : my_sb

Am I missing something? Does ovm_scoreboard do some kind of weird override thing with check()?

Do you have a sample log file to show (the last 50 lines), need to see if test ends cleanly. Maybe you have a global_stop_request in a sequence?

Try to add a return type:


function void check();
 $display("end of test");
 endfunction : check

Incisiv from Cadence gave me a compilation error without the “void”.

Oops, sorry that was a typo from when I made the example. The actual code has “virtual function void extract/check”. Sorry about that!

I’m using someone else’s build tools so I will try to see if I can get just OVM log output soon…

It looks like my OVM testbench isn’t properly configured and the tests aren’t being properly shutdown. I’m working to figure out how to do the proper configuration.

Sorry I couldn’t get log files right now. Thanks for your help, though!
