Abstract

The explosive growth of generative AI and large language models (LLMs) has created an unprecedented compute-interconnect co-design challenge. As AI accelerators scale to tens of thousands of chips per cluster, data movement has surpassed computation as the dominant consumer of power and the primary limiter of system performance. This tutorial addresses the critical interconnect technologies that enable next-generation AI computing: the scaling of serial links toward 224Gbps per lane and advanced crosstalk cancellation techniques for high-density parallel interfaces. We will present fundamental physical limits, state-of-the-art circuit architectures, and emerging solutions from leading industry and academic groups. Special emphasis will be placed on how interconnect design is evolving to meet the unique requirements of AI computing workloads, including low latency, high energy efficiency, and massive bandwidth density. Attendees will gain deep insights into the cross-layer design tradeoffs spanning circuits, packaging, and system architecture that are shaping the future of computing systems. This tutorial is intended for circuit designers, system architects, and researchers working in high-speed communication, VLSI design, and AI hardware acceleration.
