NAME

vrename - change signal names across many Verilog files

SYNOPSIS

   vrename <filename_or_directory>...
 
 

DESCRIPTION

Vrename will allow a signal to be changed across all levels of the design hierarchy, or to create a cross reference of signal names. (It actually includes module names, macros, and other definitions, so those can be changed too.)

Vpm uses a three step process. First, use

     vrename --list  [<file.v>...]  [<directory>....]
 
 

This reads the specified files, or all files below the specified directory, and creates a signals.vrename file.

Now, edit the signals.vrename file manually to specify the new signal names. Then, use

     vrename --change [<file.v>...]  [<directory>....]
 
 

ARGUMENTS

vrename takes the following arguments:
--help
Displays this message and program version and exits.
--version
Displays program version and exits.
--change
Take the signals file signals.vrename in the current directory and change the signals in the design as specified by the signals file. Either --list or --change must be specified.
--changefile {file}
Use the given filename instead of ``signals.vrename''.
--crypt
With --list, randomize the signal renames. With --change, compress spaces and comments and apply those renames listed in the file (presumably created with vrename --list --crypt).

The comment /*ENCRYPT_ME*/ must be included in all files that need to be encrypted, or use the --cryptall flag. If a signal should not be encrypted, it can simply be set in the signals.vrename list to be changed to itself. After encrypting, you may want to save the signals.vrename file so you have a key for decoding, and also so that it may be used for the next encryption run. When used in this way for the next encryption run, only new signals will get new encryptions, all other encryptions will be encrypted the same.

--cryptall
As with --crypt, but put cryptic names into signals.vrename even if the file does not include ENCRYPT_ME. Generally you will then need to edit the signals.vrename file manually to exclude any top level signals that should be preserved.
--keywords
Include keywords in the renaming list. Default is to ignore keywords, as changing a keyword will probably result in unrunnable code, however, occasionally it may be necessary to rename signals which happen to match the name of keywords recently added to the language (such as 'bit').
--list
Create a list of signals in the design and write to signals.vrename. Either --list or --change must be specified.
--nowrite
Don't write the actual changes, just report the files that would be changed.
--o {dir}
Use the given directory for output instead of the current directory.
--read
Read the changes list, allows --list to append to the changes already read.
--xref
Include a cross reference of where the signals are used. --list must also be specified.
