Auto router in Klayout?

Dear all,

I want to develop a very basic auto router in klayout. Maybe only specifying the start and the end point with mouse or passing a file with the specific points to connect.

I don't know how to start. I imagine that if I have my start points, my end points,the area allowed to route and the function to calcule the next point to reach to the end point, it is possible.

I know that there are some open programs as layoutEditor ( calling FreeRouter) that it allows to do autorouting. The problem is that you have to specify the connections and the schematic an I don't know how to extract this information from thee . gds or how when I generate the .ds file, what morre information is necessary to do autorouting.

Any suggestion or help?

Thanks
