I found the strange behavior in Verilog-Perl 2.370 release.
When I add new wire using with new_net() function.
verilog_text() generate wrong verilog sytax code (missing wire declaration).

----- Test code ------------------------------
#! /usr/bin/env perl

use strict;
use Verilog::Netlist;
use Verilog::Netlist::Net;

my $nl = new Verilog::Netlist (keep_comments=>1);
$nl->read_file (filename=>"test.v");
$nl-> link();

my $module = $nl -> find_module ("test");
my $newNet = $module -> new_net (name=>"new_wire");

print $module -> verilog_text();

----- Test code ------------------------------
----- Test data ------------------------------
module top;
wire a;
wire b;

test inst1


module test (
input a,
output b
----- Test data ------------------------------

Above sample generate,
user@hoge[130]% ./
module test (
a, b);
input a;
output b;
new_wire; <---- Here. No wire declaration.

So, I modified Verilog::Netlist::Net as,

$type = "output" if $self->port->direction eq "out";
$type = "inout" if $self->port->direction eq "inout";
+ else
+ {
+ $type = "wire";
+ }
$type .= " signed" if $self->signed;
return $type;

--------- Patch -------------------------------------------

Then I confirm this problem is fixed.

module test (
a, b);
input a;
output b;
wire new_wire;

P.S. At first I tried to create bitcard account, but I can not enter
event I
create account. So I directory sent this message.

When you call new_net, pass in a type of wire like this:
new_net(name=>'....', type=>'wire')

and it will be correctly created. I'll make the type=>wire addition
be the default in the next release.
