Routing Region

The routing region is an attribute attached to an existing LogicLock^® Plus placement region. The routing region must encompass the existing LogicLock^® Plus placement region. To define the routing region, double-click the Routing Region cell in the LogicLock^® Plus Regions window, and select from the drop-down menu.

Valid Routing Region options are:

Unconstrained—the routing shape has no constraints.
Whole chip—allocates the entire chip for the routing shape.
Fixed with expansion—allocates an expansion length for the routing shape.
Custom—Allows you to make a custom shape routing region around the LogicLock^® Plus region. When you select the Custom option, the placement and routing regions move independently in the Chip Planner.

Note: The routing shape must fully include the placement shape.

You set the routing region in the LogicLock^® Plus Routing Region Settings dialog box. Open this dialog box by clicking the Routing Region column for your region.
