Silicon Photonics Design Tools for GDSII Files.
Project description
Silicon Photonics Design Tools for GDSII Files. It is based on gdspy(heitzmann/gdspy: Python module for creating GDSII stream files, usually CAD layouts. (github.com)) and can interact with it.
Dependency
Python3 (3.6, 3.7, 3.8)
gdspy
scipy
numpy
Installation
use pip:
pip install splayout
or download from the source and build/install with:
python setup.py install
