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.
