Hi,Is it possible not connect power the VCCIO voltage on unused banks in Arria 10 devices (for example, leave unconnected)?
Hi,Yes, you can power down the VCCIO voltage of unused I/O banks except I/O Bank 2A in Intel® Arria® 10 devices. I/O Bank 2A is not allowed to be powered down because the I/O Bank is monitored by the Power-On Reset (POR) circuitry. https://www.altera.com/support/support-resources/knowledge-base/component/2018/it-is-possible-to-pow...

Hi,explain, please, that means "power down": 1. I can switch off VCCIO voltage of unused I/O banks after the power-on all FPGA VCCIO voltage? or: 2. I can not connect VCCIO voltage of unused I/O banks on the pcb board and leave VCCIO pins of unused I/O banks float?
HI,Both options can be considered, But option one is the better choice considering the feasibility of modification if required. Best Regards, Anand Raj Shankar (This message was posted on behalf of Intel Corporation)
