Installation#

We only support Python 3.11 or 3.12, and recommend VSCode IDE and UV. You can install UV on a terminal with the following commands:

# On macOS and Linux.
curl -LsSf https://astral.sh/uv/install.sh | sh
# On Windows.
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Then you can install dodata with:

uv pip install "dodata[demos]" --upgrade

Setup#

Ensure you create a .env file in your working directory with the following contents:

dodata_url = 'https://your.dodata.url.here'
dodata_user = 'dodata_user'
dodata_password = 'dodata_web_password'
dodata_db = 'your.dodata.database.url.here'
dodata_db_user = "db_username_here"
dodata_db_password = "db_password_here"
dodata_db_name = "dodata"
data_db_port = 5432
debug = False

The .env file should be in the same directory where you run the notebooks or in a parent directory.

Run notebooks#

To run the notebooks, you can use either VSCode or JupyterLab:

  • VSCode: Ensure you select the same Conda Python interpreter where the packages were installed.

  • JupyterLab: Launch JupyterLab by running jupyter-lab from the same terminal used for the installation.

Run the notebooks in the following order:

  • 1_generate_layout: Generates the GDS layout and a CSV device manifest, including device coordinates, settings, and analysis.

  • 2_generate_measurement_data: Generates CSV measurement data.

  • 3_upload_measurements: Uploads wafer definitions, measurement data and trigger analysis.

  • 4_download_data: Downloads analysis using specific queries.

  • 5_delete: Deletes data as needed.
