KLayout support of GDS and OASIS file formats with automatic uncompression of zlib compatible formats. Easily load, visualize, and edit all your files. Although a comparatively simple piece of software, a layout viewer is not only just a tool for the chip design engineer. Today's design's complexity requires not only a simple "viewer". Rather, a viewer is a microscope through which the engineer looks at the design.

There are numerous viewers available, but sadly there are not many which satisfy a few basic requirements. Most of them are commercial and expensive. If there is a need for a simple, yet powerful viewer - here it is. Download KLayout for Windows PC today!
