Existing approaches optimize circuit PPA (Power, Performance, Area) by aggregating multiple objectives into a single scalar reward, making it difficult to simultaneously generate diverse Pareto-optimal solutions across different trade-offs such as low power, low latency, and small area. However, in practical design, the relative importance of each objective varies depending on product requirements and design constraints; thus, obtaining a diverse and high-quality candidate set is beneficial in that designers can choose a preferred trade-off a posteriori. In this work, we are the first to propose a learning method for LLM-based circuit generation that optimizes, not the quality of a single circuit, but the quality and diversity of the entire circuit set obtained through multiple generations in the PPA objective space. The proposed method consists of (1) a generation-based training pipeline that reformulates coverage improvement of the entire Pareto solution set into a sequential circuit generation problem, and (2) a reward function based on Hypervolume Contribution (HVC) that measures how much a generated circuit contributes to the Pareto front. Evaluation on the RTLLM v2 benchmark shows that the proposed method achieves +13.3 percentage points in relative Hypervolume over a baseline without PPA optimization and +14.4 percentage points over a single-objective reinforcement learning method, while also demonstrating superiority in circuit diversity.","source_kind":"rss","canonical_source_url":""}],"modelAnswers":[{"id":"394debb0-f758-47ba-bbb9-0baa89762c20","model_id":"f5ce97b1-a98b-4a36-9e42-70bf4a8d7a21","model_name":"

该研究宣称首次提出面向LLM电路生成的训练方法，不是只优化单个电路质量，而是优化多次生成所得整个电路集在PPA目标空间中的质量和多样性。方法包括两部分：一是基于生成的训练流程，把整个Pareto解集覆盖率的提升重新表述为序列电路生成问题；二是采用基于超体积贡献的奖励函数，衡量新生成电路对现有Pareto前沿的贡献。评估在RTLLM
