Problem witch implementing big automaton

Hi,

never tried to use such a huge FSM but...

Quartus is problably trying to use one hot encoding.

You can try and add the following, to have Quartus use a sequential encoding, which

attribute syn_encoding : string;

attribute syn_encoding of state_reg : type is "sequential";

That said.. 70k states? *wow*

It's hard to see what your application is but 70k states is .. a lot.

Probalbly, you should consider other aproaches.

Maybe a 8 bit embedded processor core would help you.
