Abstract(in English) | In order to achieve a shorter clock period by a clock tree with less wire length and less power consumption, a clustering based clock scheduling algorithm was proposed. In the algorithm, first registers are partitioned into clusters by their locations, and then clusters are modified to improve the clock period by changing the cluster to which a critical register belongs. However, in the modification of clusters, excessive modifications are carried out because critcal registers which break cycle are not identified well. In this paper, we propose a method that reduces the number of modification by identifying critical register. Critical registers are identified by extracting non trivial strongly connected components of critical constraint graph. In experiments, the validity of the enhancement is confirmed. |
