Hello everybody,

I have a question, we have a similar problem on a few pieces of Arria II GX EP2AGX65DF25C6. After power up we found VCCA_PLL(2.5V) pins shorted to GND. Power supply rail voltages are correct and without overshooting. Power supplie 2.5V are derived from LDO and filtered.

Thank you very much for your answer.
