3.5.3. Placement Settings for the F-Tile 25G Ethernet IP Core

The Quartus Prime software provides the options to specify design partitions and Logic Lock (Standard) or Logic Lock regions for incremental compilation, to control placement on the device. To achieve timing closure for your design, you might need to provide floorplan guidelines using one or both of these features.

The appropriate floorplan is always design-specific, and depends on your design.
