2.5.13. VCCIO_PIO Supply for Unused HSIO Banks

When the entire HSIO bank is unused, you may connect the VCCIO_PIO pin of the unused HSIO bank to 0 V, 1.0 V, 1.05 V, 1.1 V, 1.2 V, or 1.3 V .

If only one of the sub-banks within the same HSIO bank is unused, you must connect the VCCIO_PIO pin of the unused sub-bank to the same VCCIO_PIO voltage level as the other actively utilized sub-bank. You must use following .qsf to assign the VCCIO_PIO of the unused sub-bank to the intended voltage supply value.

set_global_assignment -name IOBANK_VCCIO <voltage supply> -section_id <sub_bank_name>

Example:

set_global_assignment -name IOBANK_VCCIO 1.1V -section_id 3B_B
