GDSFactory+ supports over 50+ PDKs and integrates with over 20 tools.

From idea to chip, seamlessly.

Powered by our Open Source ecosystem

GDSFactory+ is built on top of battle-tested open source engines for layout, simulation, and circuit modeling

GDSFactory

Layout

The world's most popular open-source chip design framework. Programmatically create, verify, and export photonic and electronic layouts.

gSim

FDTD & FEM

Full-wave electromagnetic device simulation. Run FDTD and FEM solvers to model light propagation, mode profiles, and S-parameters.

MEOW

Eigenmode Expansion (EME)

Eigenmode Expansion Method solver. Efficiently simulate tapers, transitions, and other structures where modes evolve along the propagation axis.

SAX

Circuit — Frequency Domain

Blazingly fast S-parameter circuit simulator. Compose component models into full photonic circuits and sweep wavelength in seconds.

Circulax

Circuit — Time Domain

Time-domain circuit simulator for photonic systems. Model transient behavior, modulation, and dynamic effects across your circuit.

Schematics, layout, and simulation — all in one editor

GDSFactory+ brings the complete chip-design workflow into VS Code, with no complex installation or specialized setup.

  • Design with code, in the schematic editor, or with our AI agent
  • Run simulations without switching between tools
  • Render and inspect layouts directly in VS Code

Catch errors early with integrated DRC and LVS

Find and fix verification issues before they become expensive downstream problems.

  • Identify DRC, connectivity, and LVS errors quickly
  • Navigate directly from an error to the affected layout
  • Compare results across design versions

Design and maintain chips with our AI agent

Our agent helps you move from component design to verified layouts and well-maintained PDKs.

  • Design components and simulate layouts
  • Find and clean up DRC errors
  • Build and maintain PDKs
AI agent assisting with chip design
Switching to GDSFactory+ has streamlined our PIC design workflow by unifying layout, schematics, simulation, and analysis in one interface.
Its Python integration enables custom models and advanced analysis that legacy EDA tools can't match.
The SAX simulator is incredibly fast, and the support team has been excellent.
GDSFactory+ is now essential to our modern PIC design process.
