18.104.22.168. Pin Guidelines for Intel® Arria® 10 EMIF IP
The I/O column, I/O bank, I/O lane, adjacent I/O bank, and pairing pin for every physical I/O pin can be uniquely identified using the Bank Number and Index within I/O Bank values which are defined in each Intel® Arria® 10 device pin-out file.
- The numeric component of the Bank Number value identifies the I/O column, while the letter represents the I/O bank.
- The Index within I/O Bank value falls within one of the following ranges: 0 to 11, 12 to 23, 24 to 35, or 36 to 47, and represents I/O lanes 1, 2, 3, and 4, respectively.
To determine if I/O banks are adjacent, you can refer to the I/O Pin Counts tables located in the Intel® Arria® 10 Core Fabric and General Purpose I/Os Handbook . You can always assume I/O banks are adjacent within an I/O column except in the following conditions:
- When an I/O bank is not bonded out on the package (contains the '-' symbol in the I/O table).
- An I/O bank does not contain 48 pins, indicating it is only partially bonded out.
- The pairing pin for an I/O pin is located in the same I/O bank. You can identify the pairing pin by adding one to its Index within I/O Bank number (if it is an even number), or by subtracting one from its Index within I/O Bank number (if it is an odd number).
For example, a physical pin with a Bank Number of 2K and Index within I/O Bank of 22, indicates that the pin resides in I/O lane 2, in I/O bank 2K, in column 2. The adjacent I/O banks are 2J and 2L. The pairing pin for this physical pin is the pin with an Index within I/O Bank of 23 and Bank Number of 2K.
