GDSFactory: Open-Source EDA for Photonics, Quantum, MEMS, and RF Chip Design
summary
Open-source Python EDA GDSFactory claims to unify parametric PDKs, layout, FDTD and circuit simulation with plugins for ANSYS and Synopsys and reports over 2 million downloads. A companion LLM pipeline Fido converts natural-language specs (via YAML) into manufacturable GDS, runs FDTD and SAT checks, and outputs layouts; benchmarks on 80 prompts show roughly 50% success rate with errors accumulating across interpreter→designer→layout stages. The demo produces KLayout-compatible GDS and S-parameter results.
