18 years agoI think that the default synthesis/fitter switches have changed since quartus has evolved from v4.2 to v7.1. You could verify the logic usage as is recommended by Rysc and BR and get to a conclusion whether something is being inferred automatically due to a synthesis switch in one version and being omitted in another. By setting similar switches in v4.2 as v7.1, you may get similar results.
