SIMBA Python Library

The Simba Python Module (aesim.simba) is a Python package that contains hundreds of functions providing direct access to SIMBA such as creating a circuit, modifying parameters, running a simulation, and retrieving results. aesim.simba is independent and does not require to have SIMBA installed to be used.


The easiest way to install the Python package is using pip:

pip install aesim.simba


aesim.simba is compatible with Windows, Macos and Linux (64-bit).


The deployment key available on your account profile page must be used to activate aesim.simba. Two methods are available:

Using Environment Variable

The easiest way to activate pysimba is to set the environment variable SIMBA_DEPLOYMENT_KEY value to your deployment key. To add a new environment variable in Windows:

  • Open the Start Search, type in “env”, and choose “Edit the system environment variables”:
  • Click the “Environment Variables…” button.
  • Set the environment variables as needed. The New button adds an additional variable.

Code-based Activation

The License can be also used to activate aesim.simba.

from aesim.simba import License
License.Activate('*** YOUR DEPLOYMENT KEY ***')

Package documentation

The package documentation is available here.


Running a simulation using the Python Library is significantly faster than using the SIMBA User Interface because there is no overhead.
