10M08SCU169I7G with vccio1B=1.8v; vccio8=3.3V (vccio1a=2.5v)Configuration pins are in banks 1B + 8
Quartus prime 18.0 standard build 614
Warning (169202): Inconsistent VCCIO across multiple banks of configuration pins. The configuration pins are contained in 2 banks in 'Internal Configuration' configuration scheme and there are 2 different VCCIOs.
The problem of this warning ID because the configuration pins are powered by different Vccio in different banks.
Solution: Enforce a configuration voltage level in the Configuration tab
Pin-planner signal list shows vccio1b=1.8 and vccio8=3.3 because I defined these io-standards on their signals in assignment-editor.
assignments > device > device and pin options > configuration : in this screen I tried with box checked/unchecked "Force Vccio to be compatible with configuration IO-voltage: but this gives no difference .... I don't see anything else I that relates to Vccio 0 config pins ? ?
I'm apologize to take so much time to get the confirmation regarding to this issue. I tested on my side and get the further confirmation from my colleague.
The rule of thumb: The VCCIO for bank 1B (bank 1 for 10M02 devices) and bank 8 must be powered up to a voltage between 1.5V – 3.3V during configuration.
Thus, as long as your Bank 1B & Bank 8 is powered up between that range, you are allowed to have different voltage or same voltage.
When I did the duplication on my side, I also got the same warning as yours:
Actually the warning that you get[Warning (169202)], is the false warning from Quartus. Quartus software Team will fixed it this false warning in future Quartus release.

I'm apologize for inconvenience.
