Quartus

Node <name> of type <name> cannot be placed on a dedicated fast pin because it has a fast input register or fast output register with registered feedback packed with it


CAUSE: The specified node of the specified type cannot be placed on a dedicated fast pin because it has a fast input register or fast output register with registered feedback packed with it.
ACTION: Remove the assignment from the specified node to allow the Fitter more flexibility in placing pins in the design. If it is a fast output register, modify the design so that it does not also have external feedback.
