1.6.2. Design Abstraction
If you remove the Empty setting from a partition, the Compiler re-implements the partition from the source. Setting a partition to Empty can reduce design compilation time because the top-level design netlist does not include the logic for the empty partition. The Compiler does not run full synthesis and fitting algorithms on the empty partition logic. Emptying a preserved partition removes all preserved information.
- Create a design partition, as Step 1: Developer: Create a Design Partition describes. Set the partition Type to Default. Any other setting is incompatible with empty partitions.
- Set the Preservation Level to Not Set, and make sure there is no .qdb for the Partition Database File option. Any other setting combination is incompatible with empty partitions.
- For the Empty option, select Yes. This setting corresponds to the following assignment in the .qsf.
set_instance_assignment -name EMPTY ON -to \ <hierarchal path of partition> -entity <name>
