Critical Warning (16248): pin is placed too close with ADC pins.

Device: MAX 10 10M08DAF256C8G Quartus version: 16.0.1 build 218 I kept receiving this critical warning message even I removed lots of redundant pin assignments to keep my design at a minimal level....

Hi Craig, Thanks very much for your reply. The whole thing is just confusing. Intel has a link as I posted in the 1st thread about the critical warning, which indicates if the pin is not in certain banks then it's fine. The other tricky part is that if I get rid of the incomplete I/O warning, I will receive the ADC critical warning. There is no way for me to get rid of both warnings, so I keep the I/O incomplete warning for now. Thanks for your advice, but we already have the board done and cannot change it at this time. I did filter the ADC channel to compensate for the noise. Thanks
