use strict;

open(FILE,'AUTOSAR.txt');
local $/;
my $var = <FILE>;
my @arr = split('\^',$var);
my $i=0;

foreach (@arr) {
    $i++;
    open(FILE1,">$i.txt");
    print FILE1 $_;
    close FILE1;
}

close FILE;

Here's a slight different answer from saiprathapreddy.obula's:

use warnings;
use strict;

my ($file) = @ARGV;

open(my $input, "<$file");

local $/ = "^";

my $i = 0;

while(<>){
    chomp;

    $i++;

    open(my $output, ">file$i.txt");
    print $output "$_"; 
}

Here is a cleaned up and tested version of the program of saiprathapreddy.obula.

use strict;
use warnings;

open(FILE,'AUTOSAR.txt');

local $/;
my $var = <FILE>;
close FILE;

my @arr = split('\^',$var);
my $i=0;

foreach (@arr) {
    $i++;
    open(FILE1,">$i.txt");
    print FILE1;
    close FILE1;
}

$,="";
$"="";
my $i=1;
open OUT ,">DATA_${i}.txt";
while(<>){
    chomp;
    my @F=split(/\^/);
    if(@F==1){
            print OUT $_,"\n";
    }
    elsif(@F>1){
            $i++;
            close OUT;
            open OUT ,">DATA_${i}.txt";
            print OUT "@F[1..$#F] \n";
    }
}
close OUT;
