Verilog::Netlist::Subclass - Common routines for all classes


  package Verilog::Netlist::Something;
  use Verilog::Netlist::Subclass;
  use base qw(Verilog::Netlist::Subclass);


  $self->info("We're here\n");
  $self->warn("Things look bad\n");
  $self->error("Things are even worse\n");


The Verilog::Netlist::Subclass is used as a base class for all Verilog::Netlist::* structures. It is mainly used so that $self->warn() and $self->error() will produce consistent results.
