This is a helper tool for automating certain tedious steps in .gds design. In particular, this tool is designed to streamline design of micro-electrode arrays (MEAs). The main features of the tool are:
- Semi-automated routing between components on a design
- Escape routing for regular rectangular arrays of components
- Transferring cells from one design to another
- Addition of parametric test structures
- Automated and semi-automated placement of dies and dicing streets on a multi-project wafer
The code relies heavily on some fantastic open-source software, namely Gdspy, Shapely, and PHIDL. For the specific versions of these packages used, see requirements.txt. Additionally, the A* implementation is a modified version of an implementation from PythonRobotics.
- Python (tested with version 3.11.9)
- see
requirements.txtfor other required packages and versions
The tool can be compiled into a .exe using PyInstaller. This is currently the recommended way of using the tool. To create the .exe, run the command:
pyinstaller --onedir --collect-all ENVIRONMENT_NAME --name PROGRAM_NAME --icon=./favicon.ico --windowed --add-data "favicon.ico;." main.py
where ENVIRONMENT_NAME is the name of the conda environment with the required packages and PROGRAM_NAME is what you want to call the output .exe.
