NAME

Verilog::EditFiles - Split Verilog modules into separate files.

SYNOPSIS

See splitmodule command.

   use Verilog::EditFiles;
   my $split = Verilog::EditFiles->new
       (outdir => "processed_rtl",
	translate_synthesis => 0,
	lint_header => undef,
	celldefine => 1,
	);
   $split->read_and_split(glob("inbound_rtl/*.v"));
   $split->write_files();
   $split->edit_file(filename=>"foo", cb => sub { return $_[0]; });

DESCRIPTION

Verilog::EditFiles provides a easy way to split library Verilog files that contain multiple modules into many files with one module per file.

FUNCTIONS

new (...)

Create a new Verilog::EditFiles object. Named parameters may be specified:

celldefine

If true, add "`celldefine" before every module statement.

lint_command

For the write_lint method, the name of the linter to use. Defaults to "vlint --brief".

lint_header

If defined, add the provided text before every module statement. Generally used to insert lint off pragmas.

outdir

Name of the directory to write the output modules to. Defaults to ".".

program

Name of the program to add to comments. Defaults to "Verilog::EditFiles".

timescale_header

If defined, add the provided text before every module statement. Generally set to the next needed to #include a timescale file. Use with timescale_removal.

timescale_removal

If set, remove any `timescales.

translate_synthesis

If 1, replace any synopsys translate on/offs with "`ifdef SYNTHESIS" and "`endif"s. If set to a string, use that string instead of "SYNTHESIS".

v_suffix

The suffix to add to convert a module name into a filename. Defaults to ".v".

verbose

If true, print what files are being read and written.

$self->read_and_split ([filenames])

Read from the specified filenames.

If there is no module statement in the file, assume it is a include file, and when write_files is called, place all of the file contents into the output. If there is a module statement, when write_files is called place all following output into a file named based on the module, with .v added.

$self->write_files()

Write all of the files created by read_and_split to the outdir.

$self->write_lint([filename=>...])

Create a shell script that will lint every file created by write_files. If a "filename" parameter is not provided, "0LINT.sh" will be written in the default outdir.

$self->edit_file(filename=>..., cb=>sub{...})

Read a file, edit it with the provided callback, and save it if it has changed. The "filename" parameter is the filename to read. The "write_filename" parameter is the filename to write, defaulting to the same name as the filename to read. The "cb" parameter is a reference to a callback which takes the string of file contents and returns the string to write back. Often the callback will simply perform a search and replace.
