# fauhdlc(1)

Compile VHDL files to intermediate code.

## NAME

fauhdlc - Compile VHDL files to intermediate code.

## SYNOPSIS

**fauhdlc** \[**flags**\] \[ **--output** *filename* \] \[ **--c-output** *filename* \] \[ **--lib** *library*  \[  *vhdl-file*  \]...\] { *vhdl-file* ...}

## DESCRIPTION

**fauhdlc** is a VHDL compiler, that will output intermediate code or C-code. It supports a subset of the VHDL 2000 standard.

## OPTIONS

These programs follow the usual GNU command line syntax, with long options starting with two dashes (\`-'). A summary of options is included below.

- **-h**, **--help**

  Show summary of options.

- **-o**, **--output** *output-file*

  Output intermediate code into *output-file*.

- **-l**, **--lib** *library-name*

  Put the following VHDL-files into the library with name *library-name*. If no **--lib** is present, all files will be put into the library "work".

- **-f**, **--freestanding**

  Do not preload any library except std.vhdl. By default, **fauhdlc** will preload common libraries (currently only std\_logic\_1164) in the appropriate library namespace. The **--freestanding** prevents this behaviour, for example if you want to override the implementation of such a library.

- **-Werror**

  Treat warnings as errors.

- **-p**, **--parse-only**

  Stop with compilation after parsing the source file(s). Mainly useful for debugging the compiler.

- **-d**, **--dot-parse** *dot-file*

  Output the raw syntax tree into *dot-file*, which can be used with the GraphViz tools.

- **-c**, **--dot-const** *dot-file*

  Output the syntax tree that exists after performing constant folding into *dot-file*, which can be used with the GraphViz tools.

- **-C**, **--c-output** *c-file*

  Generate output as a C file *c-file*, that can be compiled with a C-compiler, e.g. **gcc**. This option is yet experimental.
