Hi,
We designed a board that uses an Arria II GX45 chip. We didn't initially figure to use all its resources, but the customer keeps piling on requirements and we've run out of stuff inside. The original chip was an EP2AGX45DF29C5N, 780 pin BGA. We stuffed a couple of boards using the bigger GX95 equivalent, and recompiled with the same design and pin list. It configures, and mostly works.
Two problems: all of the bank 6 I/Os are dead, all hi-z. And the PCI Express is dead. We've worked mostly on the bank 6 issue. The three VCCio6 pins are the same, and are known good. We can't, from the documentation, find any pin differences that would take out this bank.
Any suggestions? Altera doesn't seem to want to help.
