Verilog::Netlist::Module - Module within a Verilog Netlist

  use Verilog::Netlist;
  ...
  my $module = $netlist->find_module('modname');
  my $cell = $self->find_cell('name')
  my $port =  $self->find_port('name')
  my $net =  $self->find_net('name')

A Verilog::Netlist::Module object is created by Verilog::Netlist for every module, macromodule, primitive or program in the design.

See also Verilog::Netlist::Subclass for additional accessors and methods.
$self->cells
Returns list of references to Verilog::Netlist::Cell in the module.
$self->cells_sorted
Returns list of name sorted references to Verilog::Netlist::Cell in the module.
$self->comment
Returns any comments following the definition. keep_comments=>1 must be passed to Verilog::Netlist::new for comments to be retained.
$self->find_port_by_index
Returns the port name associated with the given index. Indexes start at 1 (pin numbers are traditionally counted from pin 1..pin N, not starting at zero. This was probably an unfortunate choice, sorry.)
$self->is_top
Returns true if the module has no cells referencing it (is at the top of the hierarchy.)
$self->keyword
Returns the keyword used to declare the module ("module", "macromodule", "primitive" or "program".) It might at first not seem obvious that programs are considered modules, but in most cases they contain the same type of objects so can be handled identically.
$self->name
The name of the module.
$self->netlist
Reference to the Verilog::Netlist the module is under.
$self->nets
Returns list of references to Verilog::Netlist::Net in the module.
$self->nets_sorted
Returns list of name sorted references to Verilog::Netlist::Net in the module.
$self->nets_and_ports_sorted
Returns list of name sorted references to Verilog::Netlist::Net and Verilog::Netlist::Port in the module.
$self->ports
Returns list of references to Verilog::Netlist::Port in the module.
$self->ports_ordered
Returns list of references to Verilog::Netlist::Port in the module sorted by pin number.
$self->ports_sorted
Returns list of references to Verilog::Netlist::Port in the module sorted by name.
$self->statements
Returns list of references to Verilog::Netlist::ContAssign in the module. Other statement types (Always, etc) may also be added to this list in the future.
$self->statements_sorted
Returns list of name sorted references to Verilog::Netlist::ContAssign in the module. Other statement types (Always, etc) may also be added to this list in the future.

See also Verilog::Netlist::Subclass for additional accessors and methods.
$self->find_cell(name)
Returns Verilog::Netlist::Cell matching given name.
$self->find_port(name)
Returns Verilog::Netlist::Port matching given name.
$self->find_net(name)
Returns Verilog::Netlist::Net matching given name.
$self->is_libcell
Returns if module declared inside a `celldefine.
$self->level
Returns the reverse depth of this module with respect to other modules. Leaf modules (modules with no cells) will be level 1. Modules which instantiate cells of level 1 will be level 2 modules and so forth. See also Netlist's modules_sorted_level.
$self->lint
Checks the module for errors.
$self->link
Creates interconnections between this module and other modules.
$self->modulename_from_filename
Uses a rough algorithm (drop the extension) to convert a filename to the module that is expected to be inside it.
$self->new_cell
Creates a new Verilog::Netlist::Cell.
$self->new_port
Creates a new Verilog::Netlist::Port.
$self->new_net
Creates a new Verilog::Netlist::Net.
$self->dump
Prints debugging information for this module.
$self->verilog_text
Returns verilog code which represents this module. Returned as an array that must be joined together to form the final text string. The netlist must be already ->link'ed for this to work correctly.
