Refer to the I/O Assignment Warnings table in the fitter report for a list of unassigned pins. You can assign these pins in the Pin Planner tool and recompile to allow programming file generation to pass.
CAUSE: The specified number of pins in the design does not have exact pin location assignments. For example, a pin may be assigned to a specific I/O bank. This information shows which pins you can assign to a location on the device.
ACTION: Add pin location assignment for all user pins.
