Custom End-to-End AI System Multiplies Productivity and Boosts RFIC Performance
Case Studies
Sphere Semi, a Palo Alto startup, built an autonomous, end-to-end AI RFIC design flow integrated with Keysight Advanced Design System (ADS) 2026. Using code-defined circuits, Python APIs, and programmatic RF circuit + EM co-simulation parallelized across a compute cluster, the AI engine generates and evaluates hundreds of manufacturable RF switch and tunable filter layouts, achieving first-pass RFIC success, ~6 dB better switch isolation, and > 30% filter area reduction.
