The increased chip complexity causes that average interconnect lengths increase and proportionallylarger and larger fraction of chip's area is occupied by interconnects. This proposal addresses several is-suesrelated to interconnects in submicron technologies.We will concentrate on simultaneous switching cross-talk noise effects in RC interconnects. Our goalhere is to develop efficient, easy to compute and accurate bounds on delay in the presence of crosstalk andto characterize and prevent propagating crosstalk signals. Besides correcting the crosstalk caused prob-lemswe will also develop methodologies of circuit optimization in the presence of crosstalk. We will developgate sizing tool, buffer insertion, spacing and net reordering which will consider both cross-talk and delay.At the same time we will explore regularity at the Boolean level to achieve layouts with mostly localinterconnects. The ultimate goal is to develop logic synthesis methodology which would produce highly reg-ular layout structures without large area penalty. We propose to continue our work on wave steered design methodology and we will develop tools for logic synthesis and physical design of such circuits.

芯片复杂性的增加导致平均互连长度增加，并且互连占据的芯片面积的比例越来越大。该提案解决了与亚微米技术互连相关的几个问题。我们将集中研究 RC 互连中的同步开关串扰噪声效应。我们的目标是在存在串扰的情况下开发高效、易于计算和准确的延迟界限，并表征和防止传播串扰信号。除了纠正串扰引起的问题外，我们还将开发存在串扰时的电路优化方法。我们将开发栅极尺寸调整工具、缓冲区插入、间距和网络重新排序，这些工具将同时考虑串扰和延迟。同时，我们将探索布尔级别的规律性，以实现主要采用本地互连的布局。最终目标是开发逻辑综合方法，该方法将产生高度规则的布局结构，而不会造成大面积损失。我们建议继续研究波导设计方法，并将开发用于此类电路的逻辑综合和物理设计的工具。
