– Mentor Graphics Corp
. announces a new routing technology package that is reported to combine the knowledge of an engineer, the skill of a board designer and the power of an autorouter. According to Mentor, this topology router combines engineering guidelines and designer intuition to improve the autorouting function by following the engineers’ guidelines for bus topology routing and then automatically mimicking typical CAD
designer manual edits to form clean bus structures.
The topology router consists of two applications. The first is a topology planner used by the engineer to plan and optimize the bus system and subsystem interconnects on the PCB. It assists component placement by allowing the engineer to plan logic pathways optimizing performance and layout.
The topology router automatically routes the bus interconnects following the pathways defined by the engineer. The resulting routing has structure and quality comparable to hand routing completed by experienced designers. The benefits according to Mentor include design cycle time reduction. The bus path data generated is stored and can be incrementally modified and reused for future designs.
According to Harry Potts, vice president and general manager of Mentor Graphics’ System Design Division, “…it has been an industry goal to mimic the talents and routing results of an experienced board designer as they follow the guidance of an engineer. By working closely with key customers we have been able to achieve this goal and supply our users with a tool that improves their productivity, quality, performance and manufacturability of the PCB."
The topology router is currently released to selective companies for evaluation and will be generally available in the fourth quarter of 2006.
