John,
That came close to working with a slight change. My explanation and/
or understanding was too weak yet. Here is another example:
.SUBCKT VtoI_opamp_BD_v2 Ibias30uA2 Res Vbias VtoI_casc2 casc en enN
gate
+ gate_filt gnd offset_en offset_enN offset_mirror_en
offset_mirror_enN vcc
+ wcdma_offset
The code needs to look for ".SUBCKT VtoI_opamp_BD_v2", then see if the
new line, next line, has a "+" sign in front of it, if yes process if
no end. As you can tell the syntax for Perl is still making my head
spin ;)
Here is what we have so far...
#!/usr/bin/perl
use warnings;
use strict;
print 'Please input the circuit name: ';
chomp( my $circuit_name = <STDIN> );
my $read_file = "${circuit_name}.cbr";
my $write_file = "${circuit_name}_Pins.list";
open READ, '<', $read_file or die "Can't open '$read_file' $!";
open WRITE, '>', $write_file or die "Can't open '$write_file' $!";
my $data;
while ( <READ> ) {
if ( s/^\.SUBCKT\s+$circuit_name\s// .. s/^\.ENDS\s+$circuit_name
\s// )
{ s/^\+//;$data .= $_;}
elsif ( $data ) {
$data =~ s/\s\w*$circuit_name.*//s; # remove non-pin data
my @pins = split ' ', $data;
print WRITE '(', join( ' ', map qq["$_"], @pins ), ")\n";
$data = undef;
}
}
close READ or die "Couldn't close '$read_file' $!";
close WRITE or die "Couldn't close '$write_file' $!";
exit 0;
Thank you!
