Usage

Installation

You have two options for installing this package:

• Clone this repository
• Install the complete sky130 PDK via open_pdks or volare. The PDK also contains this package.

For this package to be available in KLayout, you need to set the environment variable KLAYOUT_PATH to point to the root directory of this repository. For example, within this repository:

KLAYOUT_PATH=. klayout -e

Or at another directory:

KLAYOUT_PATH=/path/to/sky130_klayout_pdk 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.
