1. A computer-implemented method comprising:
receiving a selection of an instance associated with an electronic design at an electronic design schematic;
selecting a corresponding instance within an electronic design layout displayed on a graphical user interface;
receiving a selection of a source topology from a plurality of stored routing topologies, wherein a routing topology refers to a way a set of instance geometries are physically connected together;
automatically extracting a routing topology prior to routing; and
routing at the electronic design layout displayed on the graphical user interface, based upon at least in part, the source topology.
