Introduction to Verilog-Perl

Written by Wilson Snyder <wsnyder@wsnyder.org>.


The Verilog-Perl library is a building point for Verilog support in the Perl language. It includes:

  • Verilog::Getopt which parses command line options similar to C++ and VCS.
  • Verilog::Language which knows the language keywords and parses numbers.
  • Verilog::Netlist which builds netlists out of Verilog files. This allows easy scripts to determine things such as the hierarchy of modules.
  • Verilog::Parser invokes callbacks for language tokens.
  • Verilog::Preproc preprocesses the language, and allows reading post-processed files right from Perl without temporary files.
  • vpassert inserts PLIish warnings and assertions for any simulator.
  • vppreproc preprocesses the complete Verilog 2001 and SystemVerilog language.
  • vrename renames and cross-references Verilog symbols. Vrename creates Verilog cross references and makes it easy to rename signal and module names across multiple files. Vrename uses a simple and efficient three step process. First, you run vrename to create a list of signals in the design. You then edit this list, changing as many symbols as you wish. Vrename is then run a second time to apply the changes.
