RE: [sv-ac] 1591is ready for review

Hi Lisa,

 

I agree with Bassam. I am also citing below my previous mail:

 

Thanks,

Dmitry

 

$past( expression1 [, [number_of_ticks] [, [ expression2] [,
[clocking_event]]]] ) .

because it makes writing scripts easier: there is no need to analyze
whether the clocking event has been provided or not; the invocation
string will remain exactly the same.

 

Here is a small Perl example:

 

sub writePastOfSig

{

          my $clockEvent = shift;

          print "\$past(sig, 1, 1, $clockEvent)";

}

 

Both invocations

 

writePastOfSig("@(posedge clk)");

 

and

 

writePastOfSig();

 

will work correctly with this definition. With the first alternative the
code of writePastOfSig should be more complex.

 

The second alternative is also consistent with the syntax of the general
function invocation:

 

list_of_arguments ::=

[ expression ] { , [ expression ] } { , . identifier ( [ expression ] )
}

| . identifier ( [ expression ] ) { , . identifier ( [ expression ] ) }

 

If so, the definition of other sampled value functions should be
rewritten accordingly.

Hi Lisa,

 

It is the norm I believe e.g. see p. 159 of LRM.

 

Thx.

-Bassam.

Hi Dmitry,

 

I did not see any errors but have one question - why do you prefer to
allow the extraneous comma at the end:  e.g. $past ( var , )

Hi all,

 

I have uploaded the proposed solution. Please, review.

 

Thanks,
