ID:18326 The design pin '<name>' has been assigned to CLKUSR pin location '<name>'. Quartus Prime auto-reserves the CLKUSR pin for calibration of transceivers and certain IOs. If the pin '<name>' will not be assigned a 100-125MHz clock, you must remove the location assignment on it. Otherwise, to remove the critical warning use the QSF assignment 'set_global_assignment -name AUTO_RESERVE_CLKUSR_FOR_CALIBRATION OFF'.

CAUSE: Quartus Prime automatically reserves the CLKUSR pin for transceivers calibration. However, a location assignment has been specified to assign a design pin to CLKUSR location. Therefore, CLKUSR pin will not be auto-reserved. To ensure that transceivers calibration happens as expected, assign this pin to a 100-125MHz clock.

ACTION: If the location assignment to the CLKUSR pin was made in error, remove the location assignment. Otherwise, to disable the warning use the QSF assignment 'set_global_assignment -name AUTO_RESERVE_CLKUSR_FOR_CALIBRATION OFF' .
