Reserved (Prevent Fitter from placing non-member logic in region)
Allows you to constrain placement of nodes and entities within the Logic Lock region.
When turned on, this option prevents the Fitter from placing nodes that are not assigned to the region inside the boundary of the region. You can reserve an area on a device by creating a fixed-size region with nothing assigned to it, and turning on Reserved. When turned off, this option allows the Fitter to place nodes that are not assigned to the region inside the boundary of the region.
