Klayout 25d View -

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.

The 2.5D view is a powerful but script-driven feature, not a simple toggle. Here's how to get started:

Electronic Design Automation (EDA) requires absolute precision. When working with complex integrated circuit (IC) layouts or Micro-Electro-Mechanical Systems (MEMS), a flat 2D top-down view does not always tell the whole story. klayout 25d view

Despite its power, the 2.5D view can sometimes run into technical hurdles, which are usually related to the OpenGL rendering engine.

Before clicking buttons, let’s clarify the terminology. A true 3D view requires volume rendering (height, width, depth). KLayout does not natively do this because it is a layout tool, not a mechanical CAD tool. Navigate to Tools > 2

: The current implementation handles approximately 100,000 polygons before performance significantly degrades. How to Use the 2.5D Viewer

: When a Layout vs. Schematic (LVS) error indicates a floating net, the 2.5D view can help visually confirm if a via is physically missing between two metal layers. Here's how to get started: Electronic Design Automation
