For efficient design, verification and validation of integrated circuits and components, it is important to have an easy-to-customize and extend workflow. Python has become the standard programming language for machine learning, scientific computing and engineering. Gdsfactory is a Python library to build chips (Photonics, Analog, Quantum, MEMs, …) that provides you with a common syntax for design (KLayout, Ansys Lumerical, tidy3d, MEEP, MPB, DEVSIM, SAX, …), verification (Klayout DRC, LVS, netlist extraction, connectivity checks, fabrication models) and validation (JAX neural network model extraction, pandas, SQL database). In this talk, we describe the Gdsfactory design automation tool. Gdsfactory provides an end-to-end workflow combining layout, verification and validation using an extensible, open-source, Python-driven flow to turn your chip designs into validated products.
