Topo R

Topo R

TopoR (Topological Router) is an EDA program developed and maintained by Eremex company, based in Russia. It is dedicated to laying out a printed circuit board (PCB). By now, it lacks schematic capture and library editing (which have to be done using third-party software), but features a powerful autorouter and a set of tools intended to reduce the amount of effort needed for manual routing of a PCB. The most recognizable feature of TopoR is absence of preferred routing directions, which results in unusual looking PCBs.
