Application-specific FPGA accelerators offer substantial performance and energy-efficiency gains across many application domains, but developing them is costly, often requiring months of specialized effort. Even with high-level synthesis (HLS), designers still need extensive hardware expertise to build high-performance accelerators.
Large Language Model agents are being explored for chip design, but most methods work directly at RTL. This study compares Direct RTL Design, Agent-based HLS Design, Post-Compiler HLS Refinement, and Post-HLS RTL Refinement, and proposes a combined workflow called Agent-based HLS with RTL Refinement (AHRR). Using FPGAs for evaluation, AHRR achieves a 2.6× geometric‑mean speedup over Direct RTL Design across an 11‑task benchmark suite, demonstrating that higher‑level abstractions and subsequent RTL refinement can improve chip design efficiency.

The paper introduces VHDLBench, a benchmark and fine‑tuning framework for large language models (LLMs) applied to VHDL-based chip design. It presents a dataset of over 18,500 syntax‑verified VHDL examples, fine‑tunes five 7B‑parameter LLMs with QLoRA, and evaluates them through a three‑level pipeline—syntax/synthesis validation, functional simulation, and FPGA prototyping on Zynq SoCs. Results show up to 92% syntax correctness and 73% functional accuracy, with DeepSeek‑Coder achieving the best performance and successful deployment on real hardware.

QiMeng-ChipV-RTL is a multi‑agent framework that tackles the challenges of generating Register‑Transfer Level (RTL) code for industrial IP‑level hardware design. By partitioning long design documents into short, localized tasks and using hierarchical planning, localized code generation, interface‑consistent merging, and AST‑guided debugging, it scales to complex specifications. Experiments on the RealBench benchmark show ChipV-RTL achieves a 45.0% pass rate, outperforming state‑of‑the‑art LLMs and agents which reach only 21.6%.
