CorrectRTL: Boost RTL Generation Quality Through Automated Self-Correction with Instruction Decomposition

Large language models (LLMs) have shown strong promise in specification-to-RTL generation.

Key points

  • Among the explorations, the self-correction paradigm has significantly advanced LLM-based RTL generation.
  • 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) Structure-oriented decomposition, (2) Snippet-based RAG, and (3) SVA-based self-correction.
  • On ScaleBench, CorrectRTL improves Pass@1 from 20.5% to 49.0% (+28.5%).
