Klayout 2.5d View -

By default, KLayout shows an isometric projection. Click and drag in the 3D window to rotate the view. Right-click and drag to pan.

KLayout. It lacks the full volumetric rendering of Cadence Virtuoso’s "3D Viewer," but for 99% of layout tasks (DRC, LVS debugging, basic reviews), the 2.5D view is superior because it is included and fast.

For MEMS devices where you are looking at sacrificial layers, air gaps, and structural polysilicon, the 2.5D view simulates the topography of the wafer after deposition. klayout 2.5d view

: Execute the script from the macro editor or the Tools > 2.5d View menu.

: It is significantly easier to spot a missing via or a misaligned metal layer when you can see the stack vertically. By default, KLayout shows an isometric projection

Ensure your script correctly identifies the layer numbers (e.g., L1 = input(1, 0) ) and that those layers are currently visible in the 2D layout. Colors in the 2.5d View - KLayout Layout Viewer And Editor

This allows you to generate 2.5D snapshots ( layout_view.save_3d_snapshot("output.png") ) during overnight verification runs. KLayout

Unlike a full 3D engine that models process topology or physics, KLayout's 2.5D engine is a . It takes flat 2D polygons from your GDSII or OASIS files and "stretches" them into the Z-dimension based on a user-defined material stack script.

Download the latest KLayout, enable OpenGL, assign your layer heights, and see your design rise off the plane.
