Could you explain me the following statements.

  •     my $str = "$amap->{inst1}($amap->{sref1}) <-> $amap->{inst2}($amap->{sref2})"; 
  • while ($ARGV[0] =~ /^([\-+])/)#Tool usage:chipgen.pl -ipxact <conf> -c
+hipcore <name> {
 $arg = substr(shift, 1);
$chipcore = shift                  if $arg =~ s/^chipcore//;
# what will be stored in $chipcore 
}

  •  print "$program_name: Processing hierarchy map: $hmap->{inst}::$hmap->{busif}\n";
  • my $str = "$imap->{inst1}($imap->{busif1}) <-> $imap->{inst2}($imap->{busif2})";

    I would be very thankful if you explain bit clearly! Thanks u in advance
