NAME¶

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

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 Verilog 2001 multidimensional signals; for the width of a signal, use msb/lsb/width. For newer applications use data_type() as it supports SystemVerilog types.

$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.
