Abstract
Described herein is an improved approach to implement routing for electrical designs. A structural routing solution is provided, where a routing system is implemented to generate a complete routing tree. A user interface is provided that captures users' design intent about topology of an electrical design, and the routing system adheres to that user's design intent about the topology throughout a layout process for the electrical design.
