This paper introduces CorrectRTL, an agentic framework that enhances RTL generation by decomposing tasks into scaffold construction and detailed implementation to prevent LLM-induced code corruption. By leveraging a new benchmark (ScaleBench) and techniques like structure-oriented decomposition and SVA-based self-correction, the method significantly improves pass rates on both simple and complex hardware designs. This work advances the practical application of LLMs in electronic design automation by addressing specific limitations in current self-correction paradigms.
CorrectRTL: Boost RTL Generation Quality Through Automated Self-Correction with Instruction Decomposition
arXiv:2610.24977v1 Announce Type: new Abstract: Large language models (LLMs) have shown strong promise in specification-to-RTL generation. Among the explorations, the self-correction paradigm has significantly advanced LLM-based RTL generation. However, two challenges limit further progress. Existing benchmarks are saturated by advanced LLMs, leaving little room to evaluate the agentic self-correction framework. The monolithic self-correction paradigm rewrites the entire design at once, where LLMs are susceptible to error confusion and corruption of originally correct code. To address the benchmark challenge, we contribute ScaleBench, a more challenging benchmark of 200 complex RTL designs. To address the challenge in methodology, we propose CorrectRTL, an agentic framework that realizes a new decompose-then-correct paradigm, in which the LLM agent explicitly decouples scaffold construction from detailed implementation. CorrectRTL contributes three core techniques: (1)~\emph{Structure-oriented decomposition}, (2)~\emph{Snippet-based RAG}, and (3)~\emph{SVA-based self-correction}. On ScaleBench, CorrectRTL improves Pass@1 from 20.5% to 49.0% (+28.5%). On VerilogEval, CorrectRTL achieves up to 96.1% Pass@1, demonstrating consistent improvements across both simple and complex designs.
