very strange QuartusII 7.1 synthesis Tool results

I haven't looked at your code closely enough to confirm this, but your posts sound like the situation where multiple instances of the exact same module are different sizes. It is normal for synthesis to implement instances of the same module differently. For example, some logic might be shared between instances.

If your APBS1, APBS2, and APBS3 are the same code and you want all instances to be identical, one solution is to synthesize the module separately and use bottom-up incremental compilation to instantiate that synthesis result for all instances.
