Plain-Language Brief

The semiconductor industry is experiencing a double revolution with the shift towards heterogeneous 2.5D chiplet systems and the integration of Large Language Models (LLMs) into Electronic Design Automation (EDA) flows. This paper analyzes the potential risks associated with these changes, focusing on attacks on chiplet systems and exploits against LLM-driven EDA pipelines. The authors propose methods for securing both chiplet systems and LLM-driven EDA pipelines, as well as discussing how LLMs can aid in improving hardware security for modern systems, including chiplets.

What the Document Says

  • The semiconductor industry is undergoing a dual revolution: the shift towards heterogeneous 2.5D chiplet systems and the integration of Large Language Models (LLMs) into Electronic Design Automation (EDA) flows.
  • These paradigms offer benefits such as yield, modularity, design productivity, etc., but also radically expand the hardware attack surface.
  • The paper provides a unified analysis of these frontiers, focusing on attacks on chiplet systems (including hardware stacks for LLM acceleration) across architectural, logical, and physical levels, as well as various exploits against LLM-driven EDA pipelines.
  • To secure chiplet systems, the authors propose a defense approach that leverages 2.5D split manufacturing and active interposers for physically isolated Root of Trust (RoT) architectures.
  • To secure LLM-driven EDA pipelines, they first identify native threats and then review state-of-the-art defense techniques.
  • The paper discusses how LLM systems can advance hardware security efforts for modern systems, including chiplets.

Raw Abstract / Excerpt

The semiconductor industry is undergoing a dual revolution: the shift toward heterogeneous 2.5D chiplet systems and the integration of Large Language Models (LLMs) into Electronic Design Automation (EDA) flows. While these paradigms offer unprecedented benefits in yield, modularity, design productivity, etc., they radically expand the hardware attack surface. This paper provides a unified analysis of these frontiers, ranging from attacks on chiplet systems (including hardware stacks for LLM acceleration) across architectural, logical, and physical levels, to various exploits against LLM-driven EDA pipelines. To secure chiplet systems, we review a powerful defense approach that leverages 2.5D split manufacturing and active interposers for physically isolated Root of Trust (RoT) architectures. To secure LLM-driven EDA pipelines, we first identify native threats and then review state-of-the-art defense techniques. Finally, we discuss how LLM systems can advance hardware security efforts for modern systems, including chiplets.
