Klayout 25d View Work (macOS UPDATED)

Unlike a true 3D viewer that might support arbitrary angles and curved surfaces, the 2.5D view in KLayout works strictly by taking 2D polygon layers and extruding them vertically. It cannot model complex process topologies (like conformal coverage) but excels at showing how different metal, poly, and diffusion layers sit on top of each other. Key Technical Requirements

A dedicated list on the right allows you to toggle specific material groups on or off, which is useful for "peeling back" upper metal layers to see lower-level transistor structures.

The 2.5D view is only available if your KLayout build was compiled with OpenGL support . klayout 25d view

Currently, the tool has a practical limit of approximately 100,000 polygons . Setting Up Your First 2.5D Scene

By exporting a net from the Net Tracer , you can visualize a specific electrical path as it moves vertically through vias and different metal layers. Colors in the 2.5d View - KLayout Layout Viewer And Editor Unlike a true 3D viewer that might support

Because semiconductor layers are often very thin relative to their width, the 2.5D view includes a on the right side of the window. Increasing this factor exaggerates the vertical dimensions, making it easier to see height variations that would otherwise appear flat. Advanced Visualization Features

Navigate to Tools > 2.5d View > New 2.5d Script . This opens the macro editor with a template based on the Design Rule Check (DRC) language. Colors in the 2

The 2.5D view respects your 2D layout settings. If you change a layer's fill color or hide it in the main viewer, it will update in the 2.5D window.
