Floorplanning with constraint extraction based on interconnecting information analysis

After the phase of high level synthesis, a lot of design information is hidden for the floorplanning process. As a result, the floorplanning process which is only aiming at decreasing area and wirelength may cause design failure for the circuits, because of ignoring some hidden constraints. In this paper, we propose a method to extract some geometric constraints based on interconnecting information analysis. And a new floorplanning algorithm with CBL representation which can handle these constraints is also proposed. And the final experimental results prove the effectiveness of our method.
