Abstract
A computerized router is provided with local protection regions in which the orientation of conductors in a given conductor layer is restricted to a particular orientation without affecting the allowable orientations of conductors in that layer in other portions of the routing area. Such local protection regions may apply to one or more signal conductor layers. This capability may be provided for a router which does not have it by the addition of artificial features to the components to be connected by the router. These features may be obstructions or conductors to be used in routing signal paths. Obstructions are sized and positioned to restrict conductors in the local protection regions to the desired orientation.
