Why use this?

KLayout is used to view, inspect, edit, and process chip-layout data. It supports GDS and OASIS formats, hierarchical layouts, DRC scripting, boolean operations, layer customization, and automation through Ruby and Python interfaces.

It is a practical choice for IC designers, photonics engineers, MEMS designers, and mask-data engineers who need a capable open-source layout environment. KLayout is especially useful for reviewing foundry outputs, preparing mask data, and automating repetitive layout operations.
