Summary :

A new approach for topological routing is proposed by W-graph. We employ a W-graph Gw(V, E, W) for indicating all nets which will be assigned to two-layer, where V is a set of all terminals, E is a set of edges corresponding to two-terminal nets and W is a set of wild components corresponding to multi-terminal nets. Such that the topological routing problem can be considered as: Given a circle H containing V in the sequence corresponding to terminals on the boundary of routing region, then drawing H Gw on a plane with minimum number of created vertices (crossing points on H).
