Hi ,
I had a doubt about VPI call back cbValueChange
what does this exactly mean and how does it work .
Suppose I want to perform a function at the posedge of signal
X (about 2000 cycles)
shall i use call back cbValueChange
or call the code from the test bench
always @posedge(X)
begin
$pli
end
Which would be more efficient
thanks
