Samna is the developer interface to the SynSense toolchain and run-time environment for interacting with our devices. Written in C++, it provides a Python API and data visualization tools for working with spiking neural networks and for processing streams of event based data. Users can easily manipulate and upload networks generated by Rockpool or Sinabs to Synsense neuromorphic chips with the help of Samna.


Rockpool is an open source Python package for developing signal processing applications with spiking neural networks. Rockpool allows you to build networks, simulate, train and test them, deploy them either in simulation or on event-driven neuromorphic compute hardware. Rockpool provides layers with a number of simulation backends, including Brian2, NEST, Torch, JAX, Numba and raw numpy. Rockpool is designed to make machine learning based on SNNs easier. It is not designed for detailed simulation of biological networks.


sinabs – an open source pytorch based library – is developed to design and implement Spiking Convolutional Neural Networks (SCNNs).
The library implements several layers that are spiking equivalents of CNN layers.
In addition it provides support to import CNN models implemented in keras conveniently to test their spiking equivalent implementation.


Aermanager enables users to quickly create fast loading datasets for training neural networks on spiking/event data. It is a python package for data management of data collected from various event driven sensors. It provided file parsesrs, data transforms and visualization tools for various standard .aer* files.
