Peking University researchers introduced LEGO, a skill-based platform that unifies large language model (LLM)-assisted digital front-end design by standardizing agent capabilities into reusable 'circuit skills'. This modular approach significantly improved RTL design generation on a hard VerilogEval v2 subset, achieving an 80.5% Pass@1 rate for challenging problems that a capable baseline LLM failed to solve, and matched state-of-the-art performance.
Key insights
- Decomposing the complex RTL design process into modular, independent steps with specialized skills significantly enhances problem-solving capabilities and reusability.
- A standardized skill specification and a hierarchical architecture enable flexible cross-project composition of capabilities, allowing the system to adapt to various design methodologies.
- Integrating iterative debugging loops with accumulated experience via a lightweight RAG mechanism is crucial for achieving high correctness and efficiency in hardware design automation.
