Document Table of Contents Late Floorplan

A late floorplan is created or modified after the design is created, when the code is close to complete and the design structure is likely to remain stable. Creating a late floorplan is typically necessary only if you are starting to use incremental compilation late in the design flow, or need to reserve space for a logic block that becomes timing-critical but still has HDL changes to be integrated. When the design is complete, you can take advantage of the Quartus® Prime analysis features to check the floorplan quality. To adjust the floorplan, you can perform iterative compilations as required and assess the results of different assignments.
Note: It may not be possible to create a good-quality late floorplan if you do not create partitions in the early stages of the design.
