Abstract: Described is an improved approach to implement EM analysis, where the analysis can be performed early stages of the design process. Tree-routing is implemented using a structural routing solution, where an automatic routing mechanism is performed to generate a complete routing tree. That routing tree is then used to perform topology-driven EM analysis at various stages of the design process.

Abstract: Described is an improved approach to implement routing for electrical designs. A structural routing solution is provided, where an automatic routing mechanism is implemented to generate a complete routing tree. The approach captures users' design intent about the topology, and the routing system adhere to that topology intent throughout the layout process.

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.
