Features

  • Coplanar Waveguide (CPW) Tools

    • Path to CPW rubymacros/make_cpw.rb
    • CPW Resonator Frequency Calculation pymacros/calc_freq.py
    • Create Grounding Straps along CPW pymacros/Make Ground Straps.py

  • FastHenry Integration

    • Generates .inp from selected shapes(paths only for now), calls FastHenry, and displays resulting Zc.mat in a dialog box.
    • FastHenry3.0 needs to be available in your path.
    • In progress
      • Boxes as well as paths
      • Ground Planes
      • Editable Material parameters
      • Finer control over parameters

  • Fabrication Tools

    • Write Job File for ASML Stepper In progress.

Installation

  • Download KLayout

  • Make sure you have Python 3.4 installed on your system, with full numpy and scipy packages. Using Anaconda to create a py34 environment is pretty easy, and you can install the full Anaconda suite (with Numpy and Scipy) automatically.

    • If you're running Anaconda with Python 2.7
    conda create --name py34 python=3.4 anaconda

    This will create an environment containing a Python 3.4 installataion and will also install all anaconda packages.

  • Clone this repository

    git clone https://github.com/calebjordan/klayout-macros

  • In KLayout Macros Development Window (F5), right click in the list of python folders, and click 'Add Location'. Add the 'pymacros' folder.

  • Do the same for the rubymacros in the ruby tab.

  • In 'pymacros/Python Startup.py', change the path names to correspond to your py34 environment. For instance,

    sys.path.append("c:/Anaconda/envs/py34/lib")
sys.path.append("c:/Anaconda/envs/py34/lib/site-packages")

  • Restart KLayout. Most functions should appear in 'Tools' menu.
