Can't find common child LogicLock region for nodes in clique <name>


CAUSE: You used the Assignment Organizer command (Assignments menu) to assign nodes to the specified clique, but you also assigned nodes in that clique to different LogicLock regions, and at least two of these regions are not related to each other as ancestor and descendant LogicLock regions. The nodes in a clique must not be assigned to different LogicLock regions unless those LogicLock regions lie along the same branch of the LogicLock region hierarchy.
ACTION: Use the Assignment Organizer command (Assignments menu) to assign all clique members to the same LogicLock region. Alternatively, delete the LogicLock region assignments and turn on the Prevent Assignment to LogicLock Regions logic option for all clique members.
