Understanding Logic Lock Region Assignments

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.

Assigning Carry Chains, Cascade Chains, and Cliques to Logic Lock Regions

Carry chains, cascade chains, and cliques can cross Logic Lock region boundaries. For example, you can assign two carry chain nodes to different Logic Lock regions.
