Description
If a 2.5V VCCIO power rail is shared with VCCH_GXB in Cyclone® IV GX or Cyclone V devices, or VCC_AUX in Arria® V, Cyclone V, Stratix® IV or Stratix V devices, a floating voltage may appear on the 2.5V VCCIO rail.
For further details about floating voltages on VCCH_GXB and VCC_AUX, refer to the related solutions.
