ID:24231 Partition "<partition_descendant>" ("<inst_name_descendant>") cannot be marked EMPTY when its parent or ancestor partition "<partition_ancestor>" ("<inst_name_ancestor>") is already marked as EMPTY. To fix this error, remove the EMPTY assignment on partition "<partition_descendant>" or remove the EMPTY assignment on parent or ancestor partition "<partition_ancestor>".

CAUSE: A partition has an EMPTY assignment, while its parent or ancestor partition already has an EMPTY assignment.

ACTION: Remove either the EMPTY assignment of the child or descendant partition or the EMPTY assignment of the parent or ancestor partition in the Quartus Setting File.
