MicroEvo uses an LLM within a feedback-driven Monte Carlo Tree Search to propose and revise processor configurations, selecting candidates with Pareto-UCT and evaluating their performance, power, and area through simulation and modeling. In an out-of-order RISC-V evaluation, Gemini-3-pro achieved mean HV 0.7936 ± 0.0059 at 20 evaluations, versus 0.5826 ± 0.0439 for NSGA-II; results reflect simulated/modelled PPA, not fabricated processors.
