| Popis: | In this paper a heuristic placement and routing method with a value propagation approach, the bubbling technique, is presented to do automatic schematic generation to match human esthetics. Algorithms embedded in the method are derived to link the schematic placement and routing in human habits. Meanwhile, the left edge algorithm is modified with channel routing aspect to achieve the compact channel size and regular channel routing. The primary considerations include circuit levelling, feedback loop detection, signal flow resolution, feedback and fanout signal routing, channel size estimation, and track assignment. The implemented system, automatic schematic generator (ASG), accepts the results of high level syntheses, schedules the schematic placement and routing, and finally, commits the browsing to the schematic editor to support friendly user interfaces. The tested examples show that the proposed system can really achieve good results which are near human design. |
