cad/py-phidl 1.0.1_3 DragonFly

PHIDL is an open-source GDS-based CAD tool for Python 2 and 3 which extends and simplifies the excellent gdspy. It strives to simplify GDSII geometry creation by making the design process layout-driven, rather than coordinate-driven. The base installation includes a large library of simple shapes (e.g. rectangles, circles), photonic structures (e.g. sine curve waveguides), and superconducting nanowire shapes (e.g. single photon detectors) which are fully parameterized. It also has a built-in quick-plotting function based on Qt (or matplotlib) which allows you view the state of any GDS object, useful when scripting geometry-making functions. It also has a very thorough tutorial as well which will walk you through the process of getting acquainted with PHIDL.
