15.7.3.1 Logic Region (Inclusive/Exclusive)

A logic region is a region that has logic assigned to it. Logic can include core logic, memory, and I/O modules. The place-and-route tool will place all the logic assigned to a logic region inside that region. The floorplanning process usually requires you to create several regions and assign logic to them.

Logic regions can either be inclusive or exclusive. If a logic region is exclusive, it means that the place-and-route tool cannot place any logic within the region other than what you have previously assigned to it. If a logic region is inclusive, the place-and-route tool can place any logic within the region. Exclusive regions are not supported for ProASIC and ProASIC ^PLUSdevices. However, exclusive regions are supported for IGLOO, Fusion, and ProASIC3 devices.
