1.1.2. Node, Entity, and Instance-Level Constraints

Node, entity, and instance-level constraints apply to a subset of the design hierarchy. These constraints take precedence over any global assignment that affects the same sections of the design hierarchy. The following tools are available in the Intel® Quartus® Prime software to specify node, entity, and instance-level constraints:
