1.5.2.2. Step 2: Developer: Define a Logic Lock Region

To reserve core resources in a Consumer project for the reserved core partition, the Developer defines a fixed size and location, core-only, reserved Logic Lock region with a defined routing region. The Consumer uses this same region in their project for core development. This region can contain only core logic.
Ensure that the reserved placement region is large enough to contain all core logic that the Consumer plans to develop. For projects with multiple core partitions, constrain each partition in a non-overlapping Logic Lock routing region.
Note: When reusing the root partition across different devices within the same family, you can only reuse the Synthesized snapshot, and you must ensure that any Fitter constraints (such as Logic Lock regions) from the Developer project do not conflict with constraints in the Consumer project.

Follow these steps to define a Logic Lock region for core development in the Developer project:

  1. Right-click the design instance in the Project Navigator and click Logic Lock Region > Create New Logic Lock Region. The region appears in the Logic Lock Regions Window. You can also verify the region in the Chip Planner (Locate Node > Locate in Chip Planner).
  2. Specify the placement region co-ordinates in the Origin column.
  3. Enable the Reserved and Core-Only options.
  4. For Size/State, select Fixed/Locked.
  5. Click the Routing Region cell. The Logic Lock Routing Region Settings dialog box appears.

  6. Specify Fixed with expansion with Expansion Length of 1 for the Routing Type. For this flow you can select any value other than Unconstrained
  7. Click OK.
  8. Click File > Save Project.
