less pre calculating possible ?

Hi,

First cyclone is not (poor), don't let Altera people here that...

It has plenty of resource to get you busy for a year.

If you mean that things were reduced and optimised away then it is because you asked the compiler to do that and possibly you ended up with few wires if at all. There is no such option as precalculate on/off. Your design entry determines any precalculations and any left as hardware. Your request is paradoxical: do you want to precalculate or do want more resource to calculate??
