GDSFactory is a Python library for programmatically designing chips (photonics, analog, quantum, MEMS), PCBs, and 3D-printable objects. Users write Python code that generates CAD files such as GDS, OASIS, STL, and GERBER, with built-in support for PDKs, DRC/LVS verification, and electromagnetic/circuit simulation.

Use cases

• design photonic integrated circuits in python
• generate GDS layout files programmatically
• run DRC and LVS verification on chip layouts
• simulate photonic components with FDTD or EME solvers
• design PCBs and 3D-printable objects from code
• build parametric cell components for a foundry PDK
• automate chip design flows with reproducible scripts

When to choose

• you want scriptable, reproducible hardware layout instead of manual CAD drawing
• you work in photonics, analog, quantum, or MEMS chip design and need PDK support
• you need an end-to-end open-source flow from layout to simulation and verification
• you prefer defining designs as Python code with version control

When to avoid

• you need a purely graphical point-and-click CAD tool without coding
• you only need schematic capture without layout generation
• your target foundry requires proprietary EDA toolchains
