You may want to check Atmels Patent portfolio.
Have heard claims that it is impossible to replicate the core without 
violating some patents.
Don't know if anyone would bother about hobbyist use of the OpenCore 
version.
You can still download the core which is a positive sign, but I really do 
not know.

Thanks for all your input.

I think it makes most sense for me to have a closer look
at PicoBlaze.

Is there a good place for PicoBlaze designs apart from the
Xilinx PicoBlaze home ? I mean some kind of community like
avrfreaks or the piclist ? A place to ask stupid newbie
questions, you know ;)

Hi Peter,
if you want to use Picoblaze, then why you don't try the free C
compiler for Picoblaze?
you can download for free on www.poderico.co.uk

Next week please check on my website for the next release of the
compiler.

Best regards,
Francesco
