[P] Prompt optimization for analog circuit placement — 97% of expert quality, zero training data

About this article

Analog IC layout is a notoriously hard AI benchmark: spatial reasoning, multi-objective optimization (matching, parasitics, routing), and no automated P&R tools like digital design has. We evaluated VizPy's prompt optimization on this task. The optimizer learns from failure→success pairs and improves the LLM's layout reasoning across iterations — no domain-specific training data required.
