I'm trying to figure out an easy way to enable weak pull ups on the unused IO pins of a Cyclone 10 GX device. Apparently there was an easy single option to select in the past (when we were implementing on a Cyclone V) that could have all unused IO pins default to having weak pull ups enabled. I'm not able to find the same simple option in either Quartus Prime Pro (22.3) or Quartus Prime Standard (21.1). I can open the pin planner and add a column to show if IO pull ups are enabled and modify them pin by pin. I can open the .pin file and see each unused pin with the label "RESERVED_INPUT_WITH_WEAK_PULLUP", but I am failing to find a way through the Quartus GUI to do this globally on unused pins as a single selectable option.
Any suggestions? Thanks!
