8.3.2. Placement Restrictions for True Differential and Single-Ended I/O Standards in the Same or Adjacent GPIO-B Bank

If you use true differential I/O standards and single-ended I/O standards in the same or adjacent GPIO-B banks, adhere to the following placement guidelines.
  • Do not place true differential and toggling single-ended I/O standards in the combinations of locations listed in the following tables.
  • From version 23.4, the Intel® Quartus® Prime software issues the following errors:
    • Compilation error—violation of the same bank placement restriction.
    • Critical warning—assignment of true differential I/O standards to pin pairs with the following pin index numbers: 0 and 1, 6 and 7, 88 and 89, and 94 and 95.
Table 35.  Restricted Pin Placement Combinations for True Differential and Single-Ended I/O Standards in the Same GPIO-B Bank

This table lists the combinations of pins and I/O standards not allowed in the same GPIO-B bank. Examples:

  • If you place a true differential I/O standard in pin pair 10 and 11, do not place single-ended I/O standards in pins 9 or 18.
  • If you place a single-ended I/O standard in pin 57 or 66, do not place a true differential I/O standard in pin pair 58 and 59.

Table 36.  Restricted Pin Placement Combinations for True Differential and Single-Ended I/O Standards in Adjacent GPIO-B Banks

This table lists the combinations of pins and I/O standards not allowed in adjacent GPIO-B banks. Examples:

  • If you place a true differential I/O standard in pin pair 6 and 7 of bank 3B, do not place single-ended I/O standards in pin 95 of bank 3A.
  • If you place a single-ended I/O standard in pin 0 of bank 2C, do not place a true differential I/O standard in pin pair 88 and 89 of bank 2D.
