Hi Monks..

Good day to all.....

Following perl code with regex statement is not working..i.e. regex statement written to call value from file inside file is not working..why is it so???

Have any one you also encountered the same problem??? Both of the following codes are not working....i.e. it is not printing the word "matched"...

use strict;
use warnings;

open (IN1, "<design_modify1.vhd") or die;
open (IN2, "<nets.txt") or die;
my @nets = <IN2>;
while (<IN1>) {
    foreach my $i (0..$#nets){
        print "matched" if m/$nets[$i]/;
        }        
}

use strict;
use warnings;

open (IN1, "<design_modify1.vhd") or die;
open (IN2, "<nets.txt") or die;
my @nets = <IN2>;
while (<IN1>) {
    foreach my $i (0..$#nets){
        my $var1= $nets[$i];
        print "matched" if m/$var1/;
        }        
}

For your reference, i am attaching other two files also here........

design_modify1.vhd has following lines of codes 

enable_pad : INBUF port map (PAD => enable, Y => enable_c);

    c_pad : INBUF port map(PAD => c, Y => c_c);
    
    b_pad : INBUF port map(PAD => b, Y => b_c);
    
    sum_pad : OUTBUF port map(D => sum_c, PAD => sum);
    
    VCC_i_0 : VCC port map(Y => VCC_0);
    
    VCC_i : VCC port map(Y => \VCC\);
    
    sum_1_SUM0_0 : XOR3 port map(A => b_c, B => a_c, C => c_c, Y => su
+m_c);
    
    carry_pad : OUTBUF port map(D => N_5, PAD => carry);
    
    a_pad : INBUF port map(PAD => a, Y => a_c);
