Abstract(in English) | Due to the rapid progress of semiconductor technology, wiring delay becomes important on determining the performance of whole circuit. So, wire length-driven hierarchical placement methods are generally used, in which clusters consisting of sets of cells are generated. While previous methods determine clusters without considering internal net information in the cluster, in this paper, we present a cluster placement method considering internal cell and net information in the cluster in the hierarchical placement. When we determine cluster placement, we consider the cells to be placed closely. So, we identify cells in the cluster as center-cells, boundary-cells and un-boundary-cells. It makes it possible to predict cell placement in the following placement stage, and the proposed method can produce good cell placement with shorter wire length. |
