Complex MEMS devices, microfluidic channels, and advanced FinFET geometries are notoriously difficult to audit in standard 2D. A 25D extrusion immediately highlights whether a via or contact layer actually intersects the intended metal tracks above and below it. 2. Streamlined Debugging of PDK Stack-ups
The KLayout 2.5D view is an indispensable tool for any layout designer working with 2D GDSII files who needs a better understanding of the vertical dimension. By bridging the gap between 2D editing and 3D reality, it significantly improves the efficiency of layout debugging and visual inspection. klayout 25d view
