RE: [sv-ec] final block scheduling

Cliff,

I'm not sure whether a final block should execute in the Reactive region, or
execute as a function that is called from within $finish. However, I do
believe that if the final block creates additional events then those events
should not be allowed to mature (i.e. execute). I suspect this what you are
observing when you execute your example: the $strobe calls are essentially
posting events into the Postponed region, which are never executed.

Subject: [sv-ec] final block scheduling

Hi, All -

I have attached a final block example that I have run on ModelSim. I don't 
think it is working yet on VCS (forgive me if this is a mis-representation).

The example did not work as I expected.

10.7 Final blocks
The final block is like an initial block, defining a procedural block of 
statements, except that it occurs at the
end of simulation time and executes without delays. A final block is 
typically used to display statistical information
about the simulation.


Based on this definition, I thought I could put $strobe commands into a 
final block and have the strobes execute before simulation finished.

Gord and I have exchanged email messages on this and he believes the final 
block should execute in the Reactive region(s), and complete the $finish 
before the $strobes can execute in the postponed region. I wanted to see 
the $strobed results too since I frequently $strobe final simulation 
results (then do a #1 $finish; - I have always hated the #1 in front of the 
$finish and I thought the final block could get me away from this ugly 
extra delay).

Opinions? The final block can have any command currently legal in a 
function, but if $strobe is never executed in a final block, then it should 
be an error to avoid final-block-usage confusion.

Regards - Cliff
