arXiv:2606.04246v1 Announce Type: new Abstract: Automatic generation of RTL code for digital hardware designs remains challenging due to long-horizon reasoning, multi-step dependencies, and strict correctness constraints in Verilog and VHDL. We present StepPRM-RTL, a novel framework that combines stepwise trajectory modeling, process-reward modeling (PRM), and retrieval-augmented fine-tuning (RAFT) to enhance both the functional correctness and reasoning fidelity of LLM-based RTL code generation. StepPRM-RTL constructs stepwise reasoning trajectories from canonical solutions, where each step c
The increasing complexity of digital hardware design, coupled with the rapid advancements in large language models, makes automated RTL code generation a critical frontier for improving efficiency and correctness.
This development indicates significant progress in leveraging AI for highly specialized engineering tasks, pushing the boundaries of what LLMs can autonomously generate and verify.
The ability of LLMs to generate functionally correct and verifiable RTL code with fewer human interventions changes the workflow for digital hardware design and verification.
