what's going on with Arria V

Guys, I need some reasonable explanation for this before I shoot an SR to Altera. I'm using Quartus 12.1, the greatest supposedly. I have exactly the same design, written in behavioral code...

I think what you are seeing is the effect of that Arria V is built using a LP process. It is the same process as used on Cyclone V. The Arria II was built using the high performance process, which is the same as Stratix III. This is probably why you see the discrepancy. However, power use for the Arria V should be much better than that of Arria II for the same circuit.

Hope that helped
