KLayout is a popular, open-source, and powerful tool for viewing and editing layout files, particularly in the semiconductor industry. The 25D view in KLayout refers to a specific way of visualizing 3D structures from 2D layout data, offering insights into the third dimension (height or depth) through the use of color and layer stacking. This guide aims to cover the basics and advanced features of using KLayout for 2.5D (or 25D) viewing:
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. klayout 25d view
Are you tired of manually setting heights for 50 layers? KLayout’s Ruby/Python API allows you to script the 2.5D configuration. KLayout is a popular, open-source, and powerful tool
: It is optimized for sections of a layout rather than entire chips; practical performance typically limits viewing to around 100,000 polygons How to Use the 2.5D View This opens the macro editor with a template
(ACM, 2024) discusses using KLayout for DRC and LVS checks, which are the foundational technologies the 2.5D view relies on for generating scripts. API Reference
