ZLayout - Advanced Electronic Design Automation Layout Library
 
A high-performance 2D/3D layout processing library optimized for EDA applications.
Features quadtree spatial indexing, efficient polygon processing, and advanced
geometric analysis for electronic circuit layout optimization.
 
Now includes a flexible component system with database-stored components and
class-based logic circuits for comprehensive EDA design workflows.
