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

Summary

Researchers have applied prompt optimization using VizPy to the challenging task of analog circuit placement, achieving 97% of expert quality. This method leverages an optimizer that learns from failure-success pairs to improve an LLM's layout reasoning across iterations, notably requiring zero domain-specific training data. This breakthrough could significantly automate and accelerate a notoriously difficult aspect of chip design.
