SBRD: Check API uses AffirmIf, why GetAffirmCount is 0?

[Ajeetha Kumari]

SBRD User guide says:
<quote>
Check a received value (ActualType) with value in scoreboard. The Match function is
used to determine if the received and expected values match. Checking is handled by
AffirmIf. As a result, if they match a log PASSED is generated, otherwise, an alert
ERROR is generated.
</quote>

I didn’t create any AlertID (yet), but was thinking the call to check API below would have incremented the AffirmCount by 1. But I see it as 0 at the end of the test and an EndOfTestCheck fails for me.


i_up_or_down <= '0';
push(SB_int, 2);
WaitForClock(i_clk, 5);
check(SB_int, 1);
i_up_or_down <= '1';
wait for 100 ns;


Failure in log:

<log>
# %% Alert ERROR in Default, Test is not Self-Checking at 350 ns
</log>

I check this at a central controlProc as:

AlertIf(GetAffirmCount < 1, "Test is not Self-Checking");

Hi Ajeetha,
Next time please provide a complete testable example, such as I have provided below. Try running this.

library osvvm ; 
context osvvm.OsvvmContext ; 
use osvvm.ScoreboardPkg_int.all ; 

entity TbSB_GetAffirmCount_1 is 
end TbSB_GetAffirmCount_1 ;

architecture GetAffirmCount_1 of TbSB_GetAffirmCount_1 is 

begin

  ControlProc : process
    variable SB : ScoreboardIdType ; 
  begin
    SetTestName("TbSB_GetAffirmCount_1") ; 
    SetLogEnable(PASSED, TRUE) ;
    TranscriptOpen ;
    SetTranscriptMirror(TRUE) ; 
    SB := NewID("SB"); 
    push(SB, 5) ; 
    check(SB, 5) ; 
    log("GetAffirmCount = " & to_string(GetAffirmCount)) ; 
    AffirmIf(GetAffirmCount > 0, "GetAffirmCount = " & to_string(GetAffirmCount));
    
    TranscriptClose ; 
    
--    AffirmIfTranscriptsMatch(VALIDATED_RESULTS_DIR) ; 

    EndOfTestSummary(ReportAll => TRUE) ; 
    std.env.stop ; 
    wait ; 
  end process ControlProc ; 

end GetAffirmCount_1 ;
