Cyclone V configuration bank I/O voltage

I have virtually the same question asked 7 years ago in this forum. (https://community.intel.com/t5/Intel-Quartus-Prime-Software/Configuration-I-O-voltage/m-p/140486#M32761). I don't think it was ...

Hello,

I am sorry you still have the same problem after 7 years. May I know what error did you receive when that box is checked?

Force VCCIO voltage to be compatible with configuration I/O voltage—Forces the VCCIO voltage of the configuration pins to be the same as the configuration device I/O voltage. If you turn off this option, the VCCIO voltage of the configuration pins may vary depending on the I/O standards used in the I/O banks containing the configuration pins. This option is available for supported device families.

Thank you.

    Sorry, it was somebody else that asked the question 7 years ago. I located it when I searched the forum before I posted. The reason for the option in Quartus to force I/O voltages in the bank to be consistent with VCCPGM was not made clear in the responses to that question. That question as well as mine referred to the Cyclone V series. After posting I realized that other chips supported by Quartus may require that the I/O in the config bank must have the same voltage as the programming voltage, so that is why the box option is there.
    While I have your attention, could you confirm that my scheme and voltage choices (JTAG voltage, JTAG pull-up voltage, config pin pull-up voltage, I/O bank 3A voltage) described in my 1st post are correct for ASx4, with config device programming via the Serial Flash Loader? Thanks a lot.
