Usage

Installation

You have three options for installing this package:

1. Option: Use KLayout's Salt package manager
   In Klayout select Tools → Manage Packages. Inside the Salt package manager under "Install New Packages" search for "Efabless_sky130", click the checkmark and apply.
2. Option: Clone this repository
   From inside the repository run this command to start KLayout in edit mode:

KLAYOUT_PATH=. klayout -e

3. Option: Install the complete sky130 PDK via open_pdks or volare
   Set the $PDK_ROOT and $PDK environment variables to point to your PDK installation. Run this command to start KLayout in edit mode:

KLAYOUT_PATH=$PDK_ROOT/$PDK/libs.tech/klayout klayout -e

Note

If the package was not installed via Salt, KLAYOUT_PATH must point to the location of the package.

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.
