LogicLock Regions

Reserve Unused Logic Cells



Turning on this option prevents the Fitter from using any unused logic cells inside a LogicLock region.

You can reserve an area on a device by creating a fixed-size region with nothing assigned to it, and turning on Reserve unused logic cells.

Carry chains containing nodes that are part of a LogicLock region are not affected by this option; the Fitter places all nodes that are part of the carry chain inside the region.
