Using reinforcement learning and inverse design with convolutional neural networks, the system can generate novel circuit architectures from scratch — without relying on human-designed templates — in a fraction of the time. A 2023 proof-of-concept 5G power amplifier achieved record performance across bandwidth, output power, and efficiency. The team also introduced diffusion models to make AI-generated designs more interpretable for debugging. Key remaining challenges include reducing AI hallucinations, improving generalizability, and building open datasets, as most simulation data is locked behind NDAs. ## Full article daily.dev links to this article rather than hosting it.
