2.3.5.2.5. Importing a Design Partition with Entity-bound Constraints
Importing a partition with entity-bound SDC files requires that you define a black box wrapper for the entity in your design. This wrapper declares a partition in which the data from the imported partition is utilized. Consider the following example with an entity named fifo_imported:

To import a design partition with entity-bound constraints, perform these steps:
- To run design synthesis, click Analysis & Synthesis on the Compilation Dashboard.
- To create a new partition within the wrapper entity, click Assignments > Design Partitions Window and specify the following options on the Assignments View tab:
- Specify the Partition Name and the Hierarchy Path of the entity instance.
- Specify Default for the partition Type.
- Specify synthesized in the Preservation Level column.
- Specify the .qdb file from the previous project as the Partition Database File

- To run a full compilation, click Compile Design on the Compilation Dashboard. The Timing Analyzer appears automatically following successful compilation.
- Verify the correct application of the entity-bound SDC file assignment in the SDC File List report.
