A hierarchical orderly layout algorithm based on channel points

Since the conventional hierarchical layout algorithm has the disadvantage of wiring chaos in large programs, so on the basis of Sugiyama layout algorithm, this paper proposes a hierarchical orderly layout algorithm based on channel points. Adjust the number of each node in the channel dynamically according to program size in order to solve the existing algorithm's overlap problems when wiring lines, Combine the generalized tensor balance idea in layout diagram to reduce cross and realize the artistic layout, the algorithm also give the corresponding line distribution and application strategy in accordance with the relative positional relationship between the calling nodes to achieve the routing orderly. Experiment results show that the algorithm has good layout efficiency. It can reduce the crossings effectively, be realized layout clearly and be implemented simply.
