KLayout is an open-source Qt-based viewer and editor for IC mask layouts, supporting formats like GDS2 and OASIS. It includes Ruby and Python scripting with optional Qt bindings for automation and custom UIs.
Use cases
- view gds2 layout files
- edit ic mask layouts
- convert gds2 to oasis
- automate layout processing with python scripts
- inspect chip design geometry
- drc and layout verification workflows
When to choose
- you need a free cross-platform GDS2/OASIS viewer and editor
- you want scriptable layout processing via Ruby or Python
- you work in EDA/IC design without commercial tool licenses
When to avoid
- you need a full commercial EDA flow with signoff DRC/LVS
- you only need lightweight command-line format conversion without a GUI
- you require non-GPL licensing for redistribution
