CAUSE: | The LogicLock region hierarchy for the specified LogicLock region is circular (that is, the specified LogicLock region is both an ancestor and descendant of at least one other LogicLock region). This message can occur when you edit the Entity Settings File (.esf) manually to create LogicLock region assignments. |
ACTION: | Delete the LL_PARENT assignment in the region's definition in the top-level ESF for the current compilation hierarchy. To avoid receiving this message in the future, Altera recommends using the LogicLock Regions window to specify LogicLock region hierarchy, rather than editing the ESF manually. |
