1.5.3. Reserved Core Entity Re-Binding

Entity re-binding allows the Consumer in a root partition reuse flow to use an entity name that is different from the Developer's reserved core partition name in the root_partition.qdb.

Entity Re-binding Example

The following example illustrates application of Entity Re-binding. You specify a value for the Entity Re-binding option in the Design Partitions Window to identify the entity bound to a reserved core partition.

Figure 16. Entity Rebinding Option in Design Partitions Window

In a root partition reuse example, the Developer's project includes the shell with entity name blinking_led, and the u_blinking_led instance. The Developer exports the root_partition.qdb that includes the root partition, and a reserved core region defined by a Logic Lock placement constraint. The reserved region is associated with the u_blinking_led instance.

The Consumer reuses the root_partition.qdb in their project. However, the entity that replaces the reserved core has a different name (blinking_led_fast) than the reserved core name (u_blinking_led) in the Developer project.

If the Consumer simply adds the u_blinking_led entity to the project without entity re-binding, an error occurs.

Rather, the Consumer can re-bind the new entity name to the reserved core partition name by setting the Entity Re-binding option to blinking_led_fast.
