fauhdlc(1) Compile VHDL files to intermediate code.


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



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


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.


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.
