ID:171041 Removed node "<name>" from Logic Lock region "<name>" -- node is used for dedicated differential I/O

CAUSE: You assigned the specified node to the specified Logic Lock region. However, because the node is used for differential I/O, the Fitter removed the Logic Lock region assignment. Nodes used to implement differential I/O cannot also have a Logic Lock region assignment.

ACTION: If you require the node to be assigned to the specified location, assign the node to a custom region. To avoid receiving this message in the future, turn on the Prevent Assignment to Logic Lock Regions logic option for the specified node.
