4. A window will appear so you can define the shape you want, the type of object the shape should be and the layers it
applies to.
We're going to make a rectangular shape that is of type Constraint Region, then we'll apply its BGA-REGION rules to all layers
of the PCB as long as they fit within that shape. And we will place that rectangle shape on top of a chip.
5. In the pop up window, select Rectangle for the shape.
6. In the Shape Use field, choose Constraint Region.
7. In the Layer field, choose All (this constraint region will apply to all layers of the PCB).
8. Now click hold and drag a rectangle or square shape across the U65 device just to test out the rule.
