=head1 NAME

vppreproc - Preprocess Verilog code using verilog-perl

=head1 SYNOPSIS

  vppreproc --help
  vppreproc [verilog_options] [-o filename] [verilog_files.v...]

=head1 DESCRIPTION

Vppreproc reads the Verilog files passed on the command line and outputs
preprocessed output to standard out or the filename passed with B<-o>.

Note vppreproc was named vppp until release 3.100, so if you're looking for
vppp, this is the right replacement.  The vppp name conflicted with another
non-Verilog related tool.

=head1 VERILOG ARGUMENTS

The following arguments are compatible with GCC, VCS and most Verilog
programs.

=over 4

=item +define+I<var>+I<value>
=item -DI<var>=I<value>

Defines the given preprocessor symbol.

=item -f I<file>

Read the specified file, and act as if all text inside it was
specified as command line parameters.

=item -f I<file>

Read the specified file, and act as if all text inside it was specified as
command line parameters.  Any relative paths are relative to the current
directory.

=item +incdir+I<dir>
=item -II<dir>

Add the directory to the list of directories that should be searched
for include directories or libraries.

=item +libext+I<ext>+I<ext>...

Specify the extensions that should be used for finding modules.  If for
example module I<x> is referenced, look in I<x>.I<ext>.

=item -y I<dir>

Add the directory to the list of directories that should be searched
for include directories or libraries.

=back

=head1 VPPREPROC ARGUMENTS

=over 4

=item --help

Displays this message and program version and exits.

=item --o I<file>

Use the given filename for output instead of stdout.

=item --dump-defines

Suppress normal output, and instead print a list of all defines existing at
the end of processing the input file.

=item --noblank

Removes empty lines from the output.  Should be used with --noline, as if
correct line numbers are needed, blank lines must be preserved for proper
accounting by the program reading the output of vppreproc.

=item --nocomment

Remove comments.

=item --noline

Remove `line directives.

=item --pedantic

Rigorously obey the Verilog spec.  This disables the `error feature, and
may disable other features that are not specified in the approved language
reference manual. Defaults false.

=item --simple

Requests simple output, an alias for --noline, --nocomment and --noblank.

=item --sythesis

Define SYNTHESIS, and ignore text bewteen "ambit", "pragma", "synopsys" or
"synthesis" translate_off and translate_on meta comments.  Note using
metacomments is discouraged as they have led to silicon bugs (versus ifdef
SYNTHESIS); see
L<http://www.veripool.org/papers/TenIPEdits_SNUGBos07_paper.pdf>.

=item --version

Displays program version and exits.

=back

=head1 LANGUAGE EXTENSIONS

Vppreproc supports the preprocessing constructs defined in the Verilog 2001
and SystemVerilog 2005 standards.

The following additional constructs may be added to your Verilog code.

=over 4

=item `__FILE__

The __FILE__ define expands to the current filename as a string, like C++'s
__FILE__.  This was incorporated into to the 1800-2009 standard (but
supported by Verilog-Perl since 2004!)

=item `__LINE__

The __LINE__ define expands to the current filename as a string, like C++'s
__LINE__.  This was incorporated into to the 1800-2009 standard (but
supported by Verilog-Perl since 2004!)

=item `error I<string>

This will report an error when encountered, like C++'s #error.

=back
