region

A generic term that refers to an assignable physical resource, or multi-cell location, in the interior of an Altera^® device. You can make assignments to regions in the Regions window of the Floorplan Editor, as well as in the Assignments Organizer (Tools menu).

You can assign a node or entity to one of the following regions:

• Anywhere on the device
• An individual MegaLAB^™ row
• An individual Excalibur^™ region
• An individual MegaLAB column
• Half of an individual MegaLAB row
• Half of an individual MegaLAB column
• An individual section
• An individual Fast region
• A custom region

When you assign a logic function to a region, the Compiler can choose the best logic cell or embedded cell within the region to use to implement the logic.
