1.5.2. Reusing Root Partitions

The root partition contains all the periphery resources, and may also include some core resources. To export and reuse periphery elements, you export the root partition. Reuse of root partitions allows you to design an FPGA-to-board interface and associated logic once, and then replicate that interface in other projects.
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.
