\subsection{Testing and Measurement}

For functional testing and verification of implementation goals, measurements
needed to be performed invarious different ways and testing software was
required.

\subsubsection{Measurements}

Measurements were performed, if not noted otherwise, with the Analog Discovery
2 from Digilent as it has 16bit digital I/O Pins as well a a Waveform generator
and 2 differential oszilloscope inputs\cite{ad2}. These were for all nescessary
measurements enough. Though due to the size and construction of the device,
which can be seen in figure \ref{fig:ad2}
errors wer encountered while performing the measurements. These are noted on 
occurance.

\subsubsection{Testing}

All testing was performed with an Atmel ATMega2560 due to it's large amount
of I/O pins, 5V I/O which is the more common voltage level on CMOS
peripherials, way of addressing pins (8 at a time) and availability.
\cite{atmega2560} All 
testing software was written for this ATMega and compiled using the avr-gcc 
from the GNU-Project.
