Abstract

The paper presents a novel repeater insertion algorithm for interconnect power minimization. The novelty of our approach is in the judicious integration of an analytical solver and a dynamic programming based method. Specifically, the analytical solver chooses a concise repeater library and a small set of repeater location candidates such that the dynamic programming algorithm can be performed fast with little degradation of the solution quality. In comparison with previously reported repeater insertion schemes, within comparable runtimes, our approach achieves up to 37% higher power savings. Moreover, for the same design quality, our scheme attains a speedup of two orders of magnitude.
RIP:一种高效的低功率混合中继器插入方案
提出了一种新的中继器插入算法,实现了互连功率最小化。我们的方法的新颖之处在于将解析求解器和基于动态规划的方法明智地集成在一起。具体地说,解析求解器选择了一个简洁的中继器库和一个小的中继器候选位置集,使得动态规划算法能够在求解质量下降很小的情况下快速执行。与先前报道的中继器插入方案相比,在可比的运行时间内,我们的方法可节省高达37%的功率。此外,在相同的设计质量下,我们的方案获得了两个数量级的加速。
