DoData Tutorials

In chip design, handling various data types efficiently is crucial:

• Simulations
• Layouts
• Verification results (DRC, LVS, etc.)
• Measurements
• Yield and qualification data

DoData provides a cutting-edge data storage solution designed specifically for the complexities of chip design. Our platform seamlessly integrates into your existing workflow, offering a scalable, efficient, and organized way to store, manage, and analyze all your critical data.

By using DoData, you can enhance efficiency, improve collaboration, and streamline your design process.

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.
