AaLLM: End-to-End Analog Circuit Design Framework Using Large Language Models

Researchers have introduced AaLLM, an open-source, end-to-end multi-agent workflow that leverages large language models (LLMs) to automate analog circuit design from topology generation to sizing. The framework, detailed in a paper on arXiv (2608.13472), addresses the limitations of conventional LLM-based approaches, which typically offer fragmented solutions focusing either on sizing or topology generation and require manual addition of technical knowledge, leading to inefficiency and hallucinations during circuit sizing. AaLLM takes user specifications as input and outputs a complete design, aiming to overcome the inherent trade-offs in meeting different specs and the inability of current methods to create innovative topologies, which often results in sub-optimal designs due to reliance on conventional topologies. By providing a comprehensive, integrated solution, AaLLM promises to streamline the time-consuming, iterative process of analog circuit design, which relies heavily on expert intuition in a nonlinear and high-dimensional design space.
