No, and it shouldn't really. You should rather include those desciptions from
other schematics, given models from libraries or type them yourself.
gschem/gnetlist allows you to interconnect things. You could even use it in a
hierarchial fashion if you wish. Just include the VHDL files into your
compilation and you will be fine.
