gdstk

C++ library for creation and manipulation of GDSII and OASIS files

Gdstk (GDSII Tool Kit) is a C++ library for creation and manipulation of GDSII and OASIS files. It is also available as a Python module meant to be a successor to Gdspy. Key features for the creation of complex CAD layouts are included: * Boolean operations on polygons (AND, OR, NOT, XOR) based on clipping algorithm * Polygon offset (inward and outward rescaling of polygons) * Efficient point-in-polygon solutions for large array sets Typical applications of Gdstk are in the fields of electronic chip design, planar lightwave circuit design, and mechanical engineering.
