Interconnect has been recognized one of ten hardest problems in nano technologies. A basic observation underlying this project is that nano-interconnect issues are much similar to that in real-world communication. Much research has been conducted to ensure the reliable, fast and secure communication over a noisy and stochastic environment. Therefore, the research is exploiting communication-theoretic principles and developing innovative signaling concepts in solving the stochastic nature of nano interconnect. The primary focus is on nano silicon technologies in CMOS with feature sizes below 100nm, and the goal is to explore ways to achieve reliable and fast signaling over the noisy and stochastically limited nano-interconnect environment. The specific objectives are1. to develop realistic-yet-simple communication models for various nano interconnect scenarios,2. To study fundamental signaling limits dictated by communication theory (estimates of achievable rates indicate up to Tbits/sec.),3. to demonstrate interconnect design techniques for nano-signaling that can potentially approach the theoretical signaling limitsThis is being made possible by a combination of several innovations that include (i) multi-wire (differential) full-duplex signaling, (ii) signal modulation, coding and equalization, and (iii) utilization, instead of avoiding, very-deep-submicron (VDSM) effects such as wave transmission for potential signaling.

互连被认为是纳米技术中十大最难的问题之一。该项目的基本观察是纳米互连问题与现实世界通信中的问题非常相似。为了确保在嘈杂和随机的环境中进行可靠、快速和安全的通信，已经进行了大量的研究。因此，该研究正在利用通信理论原理并开发创新的信号概念来解决纳米互连的随机性质。主要重点是特征尺寸低于 100nm 的 CMOS 纳米硅技术，目标是探索在嘈杂且随机限制的纳米互连环境中实现可靠和快速信号传输的方法。具体目标是1．为各种纳米互连场景开发现实而简单的通信模型，2。研究通信理论规定的基本信令限制（可达到的速率估计最高可达 Tbits/秒），3。演示可能接近理论信号极限的纳米信号互连设计技术这是通过多项创新的组合实现的，这些创新包括（i）多线（差分）全双工信号，（ii）信号调制、编码和均衡，以及（iii）利用而不是避免非常深亚微米（VDSM）效应，例如潜在信号的波传输。
