Project description

Open Band Parameters Device Simulator (OBPDS)

A free, open-source technology computer aided design software for simulating semiconductor structures and devices.

OBPDS currently provides 1D electrostatic simulation of III-V compound semiconductor heterostructures, similar to Prof. William Frensley’s Bandprof. Materials parameters are provided by the Open Band Parameters sister project.

If you would like to try OBPDS before installing it, check out the interactive tutorial.

The source code is graciously hosted by GitHub.


In order to use OBPDS, you must having a working Python distribution installed. Python 3 support has not yet been tested, so Python 2.7 is suggested.

From PyPi

This is the recommended method for installing OBPDS. PyPi is the python package index, which contains many python packages that can be easily installed with a single command. To install OBPDS from PyPi, open up a command prompt and run the following command:

pip install obpds

From Source

In order to install OBPDS from source, you must fist install the following prerequisite packages:

Once these are installed, download the latest release .zip or .tar.gz source package from the github releases page, extract its contents, and run python install from within the extracted directory.


Interactive documentation is hosted through If you have difficulty accessing the interactive version, a static version is available here.
