NAME¶

Verilog::Netlist::Pin - Pin on a Verilog Cell

SYNOPSIS¶

  use Verilog::Netlist;
  ...
  my $pin = $cell->find_pin('pinname');
  print $pin->name;

DESCRIPTION¶

A Verilog::Netlist::Pin object is created by Verilog::Netlist::Cell for for each pin connection on a cell. A Pin connects a net in the current design to a port on the instantiated cell's module.

ACCESSORS¶

See also Verilog::Netlist::Subclass for additional accessors and methods.

$self->cell

Reference to the Verilog::Netlist::Cell the pin is under.

$self->comment

Returns any comments following the definition. keep_comments=>1 must be passed to Verilog::Netlist::new for comments to be retained.

$self->delete

Delete the pin from the cell it's under.

$self->module

Reference to the Verilog::Netlist::Module the pin is in.

$self->name

The name of the pin. May have extra characters to make vectors connect, generally portname is a more readable version. There may be multiple pins with the same portname, only one pin has a given name.

$self->net

Reference to the Verilog::Netlist::Net the pin connects to. Only valid after a link. This function is deprecated; use nets or nets_sorted instead.

$self->nets

Array of hashes the pin connects to. Each hash contains a msb, lsb, and net (a Verilog::Netlist::Net). Only valid after a link.

$self->nets_sorted

Array of sorted hashes the pin connects to. Each hash contains a msb, lsb, and net (a Verilog::Netlist::Net). Only valid after a link.

$self->netlist

Reference to the Verilog::Netlist the pin is in.

$self->netname

The net name the pin connects to. This function is deprecated; use pinselects instead.

$self->pinselects

The net names the pins connect to, as an array of Verilog::Netlist::PinSelection elements.

$self->portname

The name of the port connected to.

$self->port

Reference to the Verilog::Netlist::Port the pin connects to. Only valid after a link.

MEMBER FUNCTIONS¶

See also Verilog::Netlist::Subclass for additional accessors and methods.

$self->lint

Checks the pin for errors. Normally called by Verilog::Netlist::lint.

$self->dump

Prints debugging information for this pin.
