Topology-Aware Bus Routing in Complex Networks of Very-Large-Scale Integration with Nonuniform Track Configurations and Obstacles

Figure 7

Three cases of compactness cost calculation. (a) Iroutes of the first or last segment, which eventually needs to be connected to the corresponding pins in the detailed routing stage. (b) All iroutes of a segment are in the same panel. (c) The iroutes of a segment are distributed in multiple panels.
