ID:12537 Ignored one or more illegal reserve pin AS_VREF keywords

CAUSE: One or more reserve pins is specified as AS_VREF, but this keyword is not legal for the target device family. As a result, the Quartus Prime software ignored the settings. This error can occur if you use a Quartus Prime Settings File (.qsf) that was created for another device family, or if you edited the QSF manually.

ACTION: No action is required.
