Quartus

Ignored LogicLock region or custom region assignments on the following nodes, which feed tri-state bus <name>, because of deep RAM placement requirements


CAUSE: You assigned the nodes listed in the submessages to a LogicLock region or custom region, but these nodes, which feed the specified tri-state bus, are in deep RAM mode. In order to satisfy placement requirements for deep RAM, the Fitter ignored the LogicLock region or custom region assignments on these nodes.
ACTION: No action is required. To avoid receiving this message in the future, use the Assignment Organizer dialog box (Tools menu) to delete the LogicLock region or custom region assignments and turn on the Prevent Assignment to LogicLock Regions logic option for these nodes.
