Comparing of systems of PCB routers

It is compared of widely used CAD Expedision, PADS, Altium designer, SPECCTRA (PCB Alegro Router) and Topological Router (TopoR) to determine the most effective system of routing of printed circuit boards. A comparison method of analysis of hierarchies T. Saaty using criteria, objectively reflecting the design parameters of the topology of the designed products, which directly depend on the efficiency and quality of systems used by procedures for automatic synthesis of the topology.
