| 摘 要： | 基于集总式互连线功耗模型，给出了一种分布式动态功耗表达式，在此基础上，采用非均匀互连线结构，提出了一种基于延时、带宽、面积、最小线宽和最小线间距约束的互连动态功耗优化模型．并在90nm和65nm CMOS工艺节点下，采用matlab软件验证了文中模型的有效性，在工艺约束下，同时不牺牲延时、带宽和面积时，所提模型能够降低30％左右的互连线功耗．该模型适用于大规模集成电路互连优化设计．

| Abstract: | Based on the lumped interconnection power model, a distributed dynamic power model is presented first. Then by adopting a non-uniform interconnection structure, a novel optimal interconnection power model is proposed, which is constrained by delay, bandwidth, area, minimum interconnection width and minimum interconnection space. The validity of the proposed model is verified by 90nm and 65nm CMOS technology. The results indicate that the proposed model can reduce power consumption as high as 30％, with the delay, area, bandwidth not deteriorated. The proposed optimal model can be used for the interconnection optimal design in large scale integrated circuits. |

| Keywords: | lumped interconnect distributed interconnect optimal power model non-uniform interconnection |
