Hi Tristan,

Yes, 0.29 is the same -- I tried the precompiled archive provided on the
website. My "bytefile.vhd" is a simple debugging-device to log certain
signals into files. I will attend it to this e-mail. If necessary, maybe
someone can make suggestions for a little improvements? I'm just
beginning to learn VHDL...
Greetings
Martin
