Think of it as looking at a tiered wedding cake from an angle: you still see each layer’s shape, but you also grasp their vertical sequence and overlap.
The 2.5D view requires a specific script to define how 2D polygons are converted into 3D shapes. 1. Requirements
KLayout’s 25D view is a , but it should not be treated as a DRC verification tool. It bridges the gap between the abstract colored polygons of a 2D editor and the physical reality of a silicon die. klayout 25d view
Instead of building a complex solid-modeling environment, you only need to define a simple text configuration mapping layers to heights. Key Benefits for IC Designers and Mask Engineers 1. Visualizing Complex Interconnects
Define a small Region of Interest (ROI) to render only the problematic layout area. Think of it as looking at a tiered
It is highly effective at visualizing 3D wiring congestion, allowing engineers to spot overcrowding in specific Z-areas.
Navigate to in the KLayout menu.
Note: KLayout’s exact menu names and plugin availability can vary by version; check the View and Layer dialogs for 3D/2.5D options or install community plugins that add stackup editors.
You might ask: Why not just export to OpenAccess or GDSII and load into a real 3D tool like FreeCAD, Blender, or Cadence Virtuoso 3D? Requirements KLayout’s 25D view is a , but
