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

Figure 6

The bits can be categorized into two types based on the preferred directions of pins. (a) The two pins of each bit have the same preferred direction, and the path connecting the two pins has an even number of bends. (b) The two pins of each bit have orthogonally preferred directions, and the path connecting the two pins has an odd number of bends.
