DespacitoPerl:

Nice, but I'd work on the code formatting a bit, it's kinda funky, making it difficult to see what you're trying to do. Also, you don't want to use "my" everywhere, only when you're declaring/defining a variable. Further, if you set a default value to your variable, you only need to set it when it would change.

So the bit you have like this:

    if (exists $identifier{$pins1}) {
    if ( ($w1 == $identifier{$pins1}{'w2'}) && ($h1 <= $identifier{$pi
+ns1}{'h2'}) ) { 
    my $start = 1;
        }
    else {
        my $start = 0;
        }
    } else {
        my $start = 0;
    }
    printf $output "$wline";
    next if (my $start == 0);

could easily be changed to:

    my $start = 0;
    if (exists $identifier{$pins1}) {
        if ( ($w1 == $identifier{$pins1}{'w2'}) && ($h1 <= $identifier
+{$pins1}{'h2'}) ) { 
            $start = 1;
        }
    }
    printf $output "$wline";
    next if (my $start == 0);

Then, seeing how it's just a chained if statement, you could further reduce it to:

    my $start = 0;
    if ( exists $identifier{$pins1}
             && ($w1 == $identifier{$pins1}{'w2'}) 
             && ($h1 <= $identifier{$pins1}{'h2'}) ) { 
        $start = 1;
    }
    printf $output "$wline";
    next if ($start == 0);

There are other improvements you could make.

I might've answered your question, or I might not have, as I didn't actually see a question.
