NAME

Verilog::Netlist::Net - Net for a Verilog Module

CONTENTS

SYNOPSIS



  use Verilog::Netlist;

  ...
  my $net = $module->find_net (signalname);
  print $net->name;



DESCRIPTION

A Verilog::Netlist::Net object is created by Verilog::Netlist::Module for every signal and input/output declaration, and parameter in the current module.

ACCESSORS

See also Verilog::Netlist::Subclass for additional accessors and methods.
$self->array Any array (vector) declaration for the net. This is for multidimensional signals, for the width of a signal, use msb/lsb/width.
$self->comment Returns any comments following the definition. keep_comments=>1 must be passed to Verilog::Netlist::new for comments to be retained.
$self->data_type The data type of the net. This may be a data type keyword (integer, logic, etc), user defined type from a type def, a range ([11:0], signed [1:0] or "" for an implicit wire.
$self->decl_type How the net was declared. A declaration keyword (genvar, localparam, parameter, var) or port if only as a port - and see the port method, or net - and see the net_type method.
$self->module Reference to the Verilog::Netlist::Module or Verilog::Netlist::Interface the net is under.
$self->lsb The least significant bit number of the net.
$self->msb The most significant bit number of the net.
$self->name The name of the net.
$self->net_type The net type, if one applies. Always a net type keyword (’supply0’, ’supply1’, ’tri’, ’tri0’, ’tri1’, ’triand’, ’trior’, ’trireg’, ’wand’, ’wire’, ’wor’).
$self->type The type function is provided for backward compatibility to Verilog-Perl versions before 3.200. Applications should change to use data_type() and/or decl_type() instead.

The type function returns an agglomeration of data_type, net_type and decl_type that worked ok in Verilog, but does not work with SystemVerilog. Calls to type() will be converted to calls to data_type, decl_type or net_type in a way that attempts to maintain backward compatibility, however compatibility is not always possible.

$self->value If the net’s type is ’parameter’, the value from the parameter’s declaration.
$self->width The width of the net in bits.

MEMBER FUNCTIONS

See also Verilog::Netlist::Subclass for additional accessors and methods.
$self->lint Checks the net for errors. Normally called by Verilog::Netlist::lint.
$self->dump Prints debugging information for this net.
$self->dump_drivers Prints debugging information for this net, and all pins driving the net.
