Researchers have developed PrefixAgent, a novel framework that leverages large language models (LLMs) to optimize the design of prefix adders, a critical component in arithmetic circuits. This LLM-powered approach breaks down the optimization into backbone synthesis and structure refinement, utilizing function calls to interact with tools and EDA feedback. The framework is trained on a large dataset of rewrite trajectories extracted from e-graphs, enhancing its optimization capabilities and generalization. Experiments demonstrate that PrefixAgent produces prefix adders with smaller areas compared to existing methods, particularly at larger bit-widths, and performs effectively within a commercial EDA flow.
