Assigning Entities and Nodes to Logic Lock Regions

When you assign an entity to a Logic Lock region, the assignment is inherited by all lower-level entities and nodes contained in that entity. You can assign an entity to a parent Logic Lock region and assign one of its sub-entities or nodes to another child Logic Lock region. The parent region should completely contain the child region.
Note: If the parent and child regions overlap, the software issues a warning. If the parent region does not contain or overlap the child region, the software issues an error.
