HORIZON: Self-evolving agent framework for hardware design as repository-level code evolution

HORIZON is a new agentic framework that treats hardware design as repository-level code evolution, using a Markdown harness compiled into a project pack with domain knowledge, evaluator, and git/runtime policy. A hands-free agent loop evolves an isolated git worktree, extending prior self-evolution work from EDA software to hardware design artifacts. The system achieves 100% benchmark completion across ChipBench, RTLLM, Verilog-Eval, and nine CVDP categories, though the authors caution these are controlled proxies and the broader chip design problem remains unsolved.
