How do variables get synthesized in this case?

My favorite is
process(reset, clock)

If you simulated nibzA.vhd, you would see what the difference between
simulation and synthesis is WRT the following simplification of your
example:

process(smelly) is
begin
  fart <= smelly;
  nose <= fn(fart);
end process;

The combinatorial processes in nibzA.vhd exhibit this mistake a few
times too.

Yes, I have not ignored the warnings, they are still there. The fact
that sythesis in Quartus II 8.0 seems to not use the simulation
understanding is of small education on such a design.

On a large design, the power density limits of a material
semiconductor may be exceeded by such differing 'easy' sythesis vs.
'lazy' simulation outcomes.

So process(all) should be augmented with process(enough) or some such
suitable enumeration generic ting.

or maybe just process() which would appear to be a useless process
template.
