Arria II GX Altmemphy DDR3 Bit Error problem

As of today, 6/13, still have not found the problem, Jheij. I have fallen back to a simple DDR3 only system, writing and reading canned 32 bit data and doing compares. So far I am not seeing any bit errors in simulation or in my design.

I suspect the real issue you and I are seeing is due to a long line somewhere, and my new test system is so small and compact, the fitter has a much easier job. I'll let you know what I find beyond that.
