RFChipAgent: Multi-Agentic AI Flow for Analog/RF Chip Design

RFChipAgent is a novel multi‑agent flow that uses large language model agents to automate end‑to‑end analog/RF circuit design under human supervision. The system comprises four key components: a retrieval‑augmented generation subsystem that pulls design knowledge from documentation, agents that handle topology selection and schematic/testbench assembly, a hybrid sizing engine that blends TPE and CMA‑ES optimization with simulator feedback, and a trust‑scored simulation database that informs future optimization runs. Validation on GF22FDSOI 60 GHz wideband mm‑wave low‑noise amplifiers demonstrates automated topology generation, specification‑driven exploration, and simulator‑guided optimization, yielding significant reductions in design effort while preserving sign‑off quality.

LOADBench: A Large Open Analog Dataset and Benchmark for Machine Learning in IC Design

The paper introduces LOADBench, a large open dataset and benchmark suite for machine learning in analog integrated circuit design. It contains over 100 operational amplifier topologies from the SkyWater130 PDK, each with detailed annotations, sizing constraints, testbenches, and thousands of Pareto-optimal sizing-performance pairs generated by NSGA-II. Six standardized benchmark tasks—inverse sizing, topology selection, sub‑circuit classification, structural circuit generation, Pareto‑membership prediction, and multi‑objective optimization—are defined with precise protocols, and all data, annotations, and reference implementations are released under an open license.
