摘　　要：基于互连线信号传输微分方程,推导非均匀互连线的电压和电流分布表达式,根据实际情况,考虑非理性激励提出包括前端驱动和后端负载的二端口非均匀互连电路各部分能量分布表达式.基于65 nm CMOS工艺参数,对方法进行计算仿真验证,计算结果与Hspice仿真结果比较误差小于5%,具有很高的精度.该方法适用于高性能全局互连的前端优化设计分析.Based on intereonnection transmission differential equation, transform voltage and current expressions are derived by incorporating appropriate boundary conditions for interconnect energy analysis. We considered a practical transmission line with driver and load to find out relation between transform input and output voltage and current responses. Interconnection energy distribution is obtained, which considers non-ideal step stimulation. In 65 nm CMOS process, the non-uniform interconnect analytic model enables to estimate energy within 5% compared with Hspice simulations. The method has high accuracy, The analytic model can be applied to front end optimizing design and analysis of high performance global interconneetion.
