Klayout 25d View ((link)) ★
The 2.5D view is a specialized tool that transforms flat, 2D layout layers into extruded 3D blocks. Each layer in your GDS file is assigned a thickness and stacked vertically to create a 3D representation. This makes it ideal for visualizing vertical layer relationships, understanding complex process stacks, and identifying metal wiring congestion in dense designs.
: You can enable this option in the viewer settings to only show the 3D extrusion of parts you have selected in the 2D layout. 5. Troubleshooting Script not showing in menu
For extremely large layouts (>10 GB GDSII), create a quick 25D view by first using Hierarchy > Flatten on selected cells, then reduce detail with Edit > Selection > Convert to polygons with a tolerance of 0.01 µm. klayout 25d view
Because it is an extrusion-based approach, it is significantly faster than rendering a true, realistic 3D model.
: Like the standard 2D view, you can adjust layer visibility and order to focus on specific parts of the stack. Tips for Better Visualization Database Units : You can enable this option in the
It cannot accurately simulate the physical structure of processes with significant non-planarization, such as STI (Shallow Trench Isolation) or advanced FinFET structures. Conclusion
Once your stackup is configured, you can manipulate the view to inspect intricate details of your design: Because it is an extrusion-based approach, it is
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
