Well, final_step is an event, which you associate with a block:

@(final_step) begin
   if (crossings < 2)
      $strobe("Could not measure period.");
   else
      $strobe("period = %g, crossings = %d",
         latest-previous, crossings);
end

There should be no difference between a $finish on the digital side and
on the analogic side - IMHO.

Fully agreed Dave. The important question is: do we execute final_step
blocks or not ?
