ABSTRACT:
Techniques are disclosed for performing topologically planar routing of System in Packages (SiPs). A routing graph can be represented by a particle-insertion-based constraint Delaunay triangulation (PCDT) and its dual. A dynamic search routing may be performed using a DS* routing algorithm to determine the shortest path on the dual graph between a start point and an end point. Based on a dynamic pushing technique, net ordering problems may be solved. A first wire can be topologically routed. Dynamic search routing of a second wire may be performed. The first wire may be pushed or detoured in response to the dynamic searching routing of a second wire.
