Klayout 25d View ((link)) Link

To bridge this gap, KLayout—the industry-standard open-source layout viewer and editor—offers a powerful feature. Unlike a fully rendered, resource-heavy 3D CAD environment, the 25D view provides a pseudo-3D perspective by extruding 2D layer geometries based on assigned height and thickness parameters. This article explores how to configure, utilize, and maximize the KLayout 25D view to improve your layout verification workflow. What is a 25D View?

Inside the 3D View pane, look for the camera icon or the dropdown menu. Ensure the view is set to (not Orthographic). Perspective gives you the "vanishing point" effect, making the depth look realistic.

: Always use the "Visible Area" or select a small sub-cell before launching the 25D renderer. Processing an entire top-level layout will significantly slow down your machine. klayout 25d view

Once installed, a new menu option will appear under > 2.5D View . Configuring the Layer Stack (The .lyp or Script Setup)

In KLayout, the 2.5D view is a specialized visualization mode that extrudes the flat, 2D polygons of your layout into 3D blocks with a specified vertical thickness. It's called "2.5D" because, unlike a true 3D model, it does not simulate complex process topologies like sloped sidewalls. Instead, it treats each layer as a simple, flat extrusion, creating a "blocks world" representation of your chip. What is a 25D View

Manually entering heights for 40+ layers in a modern CMOS process is inefficient. You can automate this by writing a macro using KLayout's API. By writing a script that binds to your Process Design Kit (PDK), you can launch a perfectly scaled 2.5D model with a single click. 2. Using Cut-Planes and Cross-Sections

Unlike a simple 3D toggle, generating a 2.5D view in KLayout requires a . This gives you immense control to define the material stack precisely. Perspective gives you the "vanishing point" effect, making

Right-click and select , then restart KLayout if prompted.

Once the stack-up is configured, click or Render . A new viewport window will appear showing your design in a 3D perspective. Rotate: Left-click and drag your mouse to spin the model.
