📝 摘要（中文）

人工智能驱动的电子设计自动化技术在VLSI电路设计中得到了广泛探索。最近，电路基础AI模型作为一种新技术趋势出现。这些模型通过自监督预训练和高效微调两个阶段进行开发，能够学习电路的内在特性，并适应特定的下游应用，如设计质量评估和功能验证。本文对电路基础模型的最新进展进行了全面调查，涵盖了130多项相关工作，提出将这些模型称为电路基础模型（CFMs），并对其输入模态、模型架构和下游应用进行了分类和讨论。

🔬 方法详解

问题定义：当前VLSI电路设计中的AI模型多依赖于标注数据，导致模型的泛化能力不足，且在新任务上的适应性较差。

核心思路：本文提出的电路基础模型通过自监督预训练和高效微调，旨在利用大量无标注数据学习电路的内在特性，从而提高模型的泛化能力和适应性。

技术框架：整体架构分为两个主要阶段：第一阶段是自监督预训练，学习电路的通用表示；第二阶段是针对特定任务的微调，应用于设计质量评估和功能验证等。

关键创新：电路基础模型的最大创新在于其双阶段的训练流程，区别于传统的任务特定模型，能够在无标注数据上进行有效学习。

关键设计：模型架构包括编码器和解码器两部分，编码器用于通用电路表示学习，解码器则利用大型语言模型进行生成任务，设计中采用了特定的损失函数和参数设置以优化性能。

📄 摘要（原文）

Artificial intelligence (AI)-driven electronic design automation (EDA) techniques have been extensively explored for VLSI circuit design applications. Most recently, foundation AI models for circuits have emerged as a new technology trend. Unlike traditional task-specific AI solutions, these new AI models are developed through two stages: 1) self-supervised pre-training on a large amount of unlabeled data to learn intrinsic circuit properties; and 2) efficient fine-tuning for specific downstream applications, such as early-stage design quality evaluation, circuit-related context generation, and functional verification. This new paradigm brings many advantages: model generalization, less reliance on labeled circuit data, efficient adaptation to new tasks, and unprecedented generative capability. In this paper, we propose referring to AI models developed with this new paradigm as circuit foundation models (CFMs). This paper provides a comprehensive survey of the latest progress in circuit foundation models, unprecedentedly covering over 130 relevant works. Over 90% of our introduced works were published in or after 2022, indicating that this emerging research trend has attracted wide attention in a short period. In this survey, we propose to categorize all existing circuit foundation models into two primary types: 1) encoder-based methods performing general circuit representation learning for predictive tasks; and 2) decoder-based methods leveraging large language models (LLMs) for generative tasks. For our introduced works, we cover their input modalities, model architecture, pre-training strategies, domain adaptation techniques, and downstream design applications. In addition, this paper discussed the unique properties of circuits from the data perspective. These circuit properties have motivated many works in this domain and differentiated them from general AI techniques.
