\chapter{Introduction}

\section{What is the BrainScale System?}

The BrainScaleS Wafer System, developed and used in the electronic visions Group at Heidelberg University is a neuromorhic hardware implementation.

For this Thesis important core components, inside the System, are the mixed-signal ASICs, named HICANNs (on Wafer in fig. \ref{wss}), and FPGAs for controlling these HICANNs \cite{hbpguidebook-brainscales}

\section{What's the PowerIt Subsystem?}

The hardware used in this thesis is a PowerIt board (fig. \ref{}), developed in the electronic visions group. It functions as power supply inside of the Waferscale System (fig. \ref{wss}).

In which it is providing the Wafer with 1.8V and the FPGAs with 9.6V. Its maximum rated Pwerdraw is 2kW.
