Revolution or Hype? Seeking the Limits of Large Models in Hardware Design

2025-09-05

AI Summary

This paper addresses the central debate on whether AI—particularly large language models (LLMs) and large circuit models (LCMs)—can revolutionarily replace or meaningfully augment traditional hardware design flows in electronic design automation (EDA), focusing on critical bottlenecks in reliability, scalability, and interpretability. Method: We conduct a systematic assessment via comprehensive literature review, multi-dimensional technical comparison across model architectures and EDA tasks, and cross-domain expert consensus analysis. Contribution/Results: We propose the first evaluation framework for foundation models in hardware design, rigorously delineating their current applicability (e.g., high-level synthesis assistance) and fundamental limitations (e.g., physical-layer verification and timing closure). The study establishes an authoritative benchmark for academia and delivers actionable guidance for industry—including viable integration pathways and risk-mitigation strategies—thereby advancing AI-EDA from conceptual exploration toward pragmatic deployment.

Abstract

Recent breakthroughs in Large Language Models (LLMs) and Large Circuit Models (LCMs) have sparked excitement across the electronic design automation (EDA) community, promising a revolution in circuit design and optimization. Yet, this excitement is met with significant skepticism: Are these AI models a genuine revolution in circuit design, or a temporary wave of inflated expectations? This paper serves as a foundational text for the corresponding ICCAD 2025 panel, bringing together perspectives from leading experts in academia and industry. It critically examines the practical capabilities, fundamental limitations, and future prospects of large AI models in hardware design. The paper synthesizes the core arguments surrounding reliability, scalability, and interpretability, framing the debate on whether these models can meaningfully outperform or complement traditional EDA methods. The result is an authoritative overview offering fresh insights into one of today's most contentious and impactful technology trends.
