Summary

The Split Plane dialog provides controls to specify the required net to which to connect the currently selected Split Plane region. A split plane is an enclosed region on an internal plane that divides the plane into separate electrically isolated areas. Each region is defined by placing boundary lines to encompass all the pins on that net. Each area is then assigned to a different net, which creates two or more split planes on the one internal power plane layer.
