The routing of bus structures on printed circuit boards (PCBs) has always required a manual process to achieve maximum densities and an aesthetically appealing look. Also, the communication of ideal bus topologies (form, layers, nets) has always been done on paper.

This white paper describes new Mentor Graphics technology that simplifies these processes, enabling bus structure topology planning to become an automated part of the design process. Bus structure topologies are captured in the design database and carried on into the physical design process, where an auto-router can efficiently route the buses. The result is a process that combines the expertise of an experienced designer with the speed of auto-routing, improving productivity and design cycle time.
