Klayout 25d View ^new^ -

KLayout utilizes OpenGL for rendering. The engine is surprisingly snappy. Even with complex standard cell blocks involving thousands of polygons, the frame rate remains interactive. The camera controls (pan, zoom, rotate) are intuitive for anyone familiar with CAD tools, defaulting to a standard "orbit" mode.

But what exactly is "2.5D"? It isn't true 3D rendering (like you’d see in Cadence Virtuoso 3D or Siemens Calibre 3DSTACK). Instead, the 2.5D view in KLayout gives you a pseudo-3D perspective where 2D polygons are extruded vertically based on layer information. This article dives deep into how to activate, configure, and leverage the KLayout 2.5D view to debug your designs faster than ever before. klayout 25d view

: While primarily for geometry, it is possible to export a specific net (e.g., from the Net Tracer ) to visualize its path through different vertical layers. Colors in the 2.5d View - KLayout Layout Viewer And Editor KLayout utilizes OpenGL for rendering
