KLayout is a Qt-based layout viewer and editor for integrated circuit and mask design work.
It’s designed to handle very large hierarchical layouts accurately while also providing editing, scripting, and verification capabilities in a single application. Alongside interactive GUI use, the project also supports automation-oriented workflows through its built-in scripting environment and related tooling.
This is free and open source software.
Key Features
- Provides fast and accurate viewing of huge layout files.
- Reads layout data in formats including GDS2, OASIS, DXF, CIF, Gerber, and LEF/DEF.
- Supports hierarchical layout editing with polygons, boxes, wires, labels, transformations, boolean operations, and other advanced editing functions.
- Offers overlay capabilities for multiple layouts together with flexible layer configuration, rulers, bookmarks, and browsers for shapes and instances.
- Includes parametrized cells for creating complex geometries and reusable layout elements.
- Integrates Ruby and Python scripting with a built-in development environment for writing and debugging automation code.
- Includes analysis tools such as XOR, layout diff, design rule checking, and layout versus schematic verification.
- Supports technology package management and the Salt add-on package manager.
- Can be built on Linux with gcc or clang using Qt, and also supports command-line and Python module oriented configurations.
