Does Quartus not optimise based on reachability analysis? If I code a counter that wraps around at 255, does it not infer an 8-bit counter? I know Max Plus II never did, but surely Quartus can do this...

Also, why do you say use signed/unsigned all the time? Most of the time, you only *need* vectors for the top level port pins. Just pass integers around your design hierarchy the rest of the time. Typing to_integer() isn't that much grief anyway is it? :-)? All IMHO of course!

Cheers,
