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 Rahul, The same message was reported in Quartus and I did check IO assignment warnings. The message was "SystemStop missing drive strength and slew rate" even though it has 12ma defautl current and 2 default slew rate, so I added 2 lines to the qsf file set_instance_assignment -name CURRENT_STRENGTH_NEW 12MA -to SystemStop set_instance_assignment -name SLEW_RATE 2 -to SystemStop But received the ADC pin too close critical warning Thanks
