Abstract(in English) | In this paper, we deal with floorplan optimization problem with module abutment constraints placing two modules abutting each other on the floorplan. Traditional methods check module abutments after decoding to a floorplan. We propose a rapid floorplan method using Segment-State Sequence (S-sequence) which distinctively encodes floorplan having different abutment topological relationships. First, we regards abutment constraints of modules as that of rooms assigned modules which have abutment constraints. Then, we present necessary and sufficient conditions to abut two modules facing to the same segment partitioning a floorplan, and we propose a judgement algorithm which checks whether two modules are abutting on the floorplan or not using S-sequence. Since our method checks abutment relationships of two rooms before decoding, we need not to decode S-sequence which do not meet abutment constraints in Simulated Annealing process, therefore, we can optimize floorplan satisfying abutment constraints rapidly. In experiments, we implemented flooaplan optimization flow with abutment judgement method, and the results show that the proposed method optimized floorplan satisfying abutment constraints more rapidly than traditional methods. |
