Hi,
In the below code, when i am calling fun this is task is displaying but when I call the fun inside the $display task, it is not displaying(this is task).
can anyone explain below code why it is not displaying
module tb;
function int fun1(int a);
int b;
fork
disp();
join_none
b = a;
return b;
endfunction
task disp();
#10;
$display($realtime," this is task ");
endtask
initial
begin
//fun1(10);
$display($realtime," outside %d ",fun1(5));
end
endmodule
The code compiles and displays what it’s supported to within the Cadence compiler:
*ncsim> run
0 outside 5
10 this is task
ncsim: W,RNQUIE: Simulation is complete.
ncsim> exit
Hi,
So if I understand you correctly, the $display statement within the initial works while the one within the task never shows, correct?
Possibly, you may want to check with Mentor why it’s not working, because it does both with Cadence Incisive and Synopsys VCS…
In reply to sylvainb:
You have the call to the function fun commented out. When I remove the comment, Questa produces the same result as the other simulators.
If after removing the comment it still doesn’t work for you, you’ll have to take that up with your tool vendor directly as this public form is not for discussing tool specific issues.
