5.4.2. Guideline: Use the Same VCCPD for All I/O Banks in a Group
One VCCPD is shared in a group of I/O banks. If one I/O bank in a group uses 3.0 V VCCPD, other I/O banks in the same group must also use 3.0 V VCCPD.
The I/O banks with the same bank number form a group. For example, I/O banks 8A, 8B, 8C, and 8D form a group and share the same VCCPD. This sharing is applicable to all I/O banks, with the following exceptions:
- Arria® V GX and GT devices—No VCCPD sharing in bank 4A and 7A. Each of these I/O banks has their own individual VCCPD.
- Arria® V SX and ST devices—No VCCPD sharing in bank 4A. In these devices, banks 6A, 6B, and 7A through 7E are HPS I/O banks.
- Arria® V GZ devices—No VCCPD sharing across banks 3A, 3B, 3C, and 3D. Banks 3A and 3B form a group with one VCCPD while bank 3C (if available) and 3D form another group with its own VCCPD.
For the Arria® V GZ devices, if you are using an output or bidirectional pin with the 3.3 V LVTTL or 3.3 V LVCMOS I/O standard, you must adhere to this restriction manually with location assignments.
