From this what i have to do is,i have to read input,output,always,and initial blocks and have to send them seperate files ie input to input_in,output_out,always to alway_all;

I am having the pblm at reading always block as it is so many internal blocks

could u anybody tell me how to read entire always block and write it to the socalled named file THis is the code I tried for input and out put reading

but i couldnt get any idea regarding the reading of whole always blcok for the above

your attempt from ravi030's scratchpad

#!usr/bin/perl

use strict;
use warnings;

open(
    my $ip_fileh, '<',

    "D:\\PacketProcessor\\rtl\\common\\gen_sync_fifo.v"
  )
  || die

  (
    "unable to open the file 

D:\\PacketProcessor\\rtl\\common\\gen_sync_fifo.v\n"
  );    #open the file

while (<$ip_fileh>) {    #read the file line by line

    my $str = $_;        #assign to a variable

    chomp $str;          #remove the new line

    if ( $str =~ m/(Input|output) ((\w+(,\s*\w+)*)|([^\n]*))/i ) {

        my $type = $1;    #get whether input or output

        my @inp_vals = split /\,\s*/, $2;    #split by comma followed 
+by space if more than one values

          local $" = "\n";    #to print the array values line by line

        print "$type\n@inp_vals \n";    #print the output

    }

}
