You are absolutely right. That was/is my primary trigger. But first I 
had to figure out how the gschem to VHDL path works. So why not let 
everybody profit from my work ;-)
Unfortunately I got stonewalled by the way gschem/gnetlist (VHDL 
backend) handles buses. I haven't solved that one.

Good point. I'll add an introduction.

Oh really? I usually use the schematics to define the architecture or 
communicate about the architecture and fill in the working block later. 
But I guess that makes me special :-)

It should not be. I'll test it on an other machine later tonight.
