Topological PCB autorouter

TopoR is a topological PCB autorouter that is claimed to meet or exceed proficient manual routing quality. Its mathematical algorithms not only reduce the overall design time but also improve the electromagnetic compatibility of the resulting boards.

Topological routing and other features simplify design tasks previously considered to be hard or impossible to fulfill. When working with TopoR a previous experience in autorouters usage is not required. It does not use obscure scripts, it is controlled interactively by a transparent and easy-to-learn graphical user interface.

It lays down tracks going in any direction, taking the shortest path; unlike other autorouters it is not restricted to orthogonal and 45° tracks. Maths deliver PCBs with a minimum possible number of vias and shortest tracks.

It routes any board almost instantly but continues generating new variants of layout, automatically selecting better variants.

Interactive editing tools include automatic and manual component movement, manual routing, changing the track's layer or width, etc and it integrates with Protel DXP or P-CAD via PCAD ASCII format with the import/export feature.
