Installation

You have two options for using this package:

When you start KLayout, you must reference this package. This can be done by setting the environment variable KLAYOUT_HOME. For example, inside this repository:

KLAYOUT_HOME=./sky130_tech klayout -e

PCells

If you would like to use the PCells, you need to install gdsfactory in your system-wide Python package installation. This can be as simple as running the following:

pip install --upgrade gdsfactory

Important

If you are using a Linux distribution that discourages the installation of system-wide Python packages through pip, you need to pass --break-system-packages.
