PCB ROUTERS AND ROUTING METHODS - …
PCB ROUTERS AND ROUTING METHODSBY: LEE W. RITCHEY, SPEEDING EDGE, COPYRIGHT SPEEDING EDGE DECEMBER 1999 FOR PUBLICATION IN FEBRUARY ISSUE OF PC DESIGN MAGAZINEINTRODUCTIONR outing of printed circuit boards has ranged from hand layout using tape on Mylar to 100%autorouting of all wires. The METHODS chosen have been driven by market place pressures andproduct complexity as well as the skill of the PCB designer. The need to complete ROUTING rapidly withlarge numbers of nets and electrical constraints, as exist in super computer like products, has driventhe development and use of specialized autorouters. At the other end of the complexity scale, PCBlayout tools have been optimized to allow hand ROUTING of virtually all wires. Some call this lattermethod electronic taping. This diverse set of design problems has given rise to two distinct ROUTING strategies and router are maze ROUTERS and X-Y based ROUTERS .
