This paper studies the buffer planning problem for interconnect centric floorplanning. Dead-spaces not held by blocks are the available location for buffer insertion. To make best use of these spaces for buffer requirements, we have to move blocks so that blocks’ room size is adjusted and dead-spaces could be redistributed. In this paper, we introduce a new algorithm to move blocks not only within its room, but also in the space currently held by other blocks by pushing away these blocks if necessary without violating the topological and the total area. After applying this method of redistributing dead-spaces, the number of nets satisfying delay constraint can be optimized.
