Analyzing the Traces
<li>Open the Analyzer software</li>
<li>From the ''File --> Open Project'' option, navigate to the .cwp file you save previously. Open this file.</li>
<li><p>Select Switch to the ''Project --> Manage TracesTrace Output Plot'' option to open tab on the dialog, enable the captured traces by adding a check-mark in the boxright side. Close the dialog with `ESC`:</p><p>[[File:tracemanage.png|image]]</p></li><li><p>If you wish to view the trace data, follow these steps:</p> <ol style="list-style-type: decimal;"><li>Switch to the ''Waveform DisplayResults'' setting tabon the left side</li><li>Switch Scroll down to the ''GeneralTrace Output Plot'' parameter setting tab, highlighted below:<p>[[File:v4_tracedraw.png|500px]]</p></li><li>You can choose to plot a specific range of traces. For example type '''0-10'' in the '''Trace(s) to plot'' window.</li><li>Hit the ''Redraw'' button when you change the trace plot range.</li><li>You can right-click on the waveform to change options, or left-click and drag to zoom</li><li>(oops there is no 6).</li><li>Use the toolbar to quickly reset the zoom back to original</li></ol> <p>[[File:traceplotting.png|image]]</p></li><li><p>You can view or change the attack Try more advanced plotting options on the , like ''Attack'' parameter settings tab:</p><ol style="list0(r),4-style-type: decimal;"><li>The 7(b)''Hardware Model'' settings are correct for the software AES by default</li><li>The ''Point Setup'' makes the attack faster by looking over a more narrow range of points. Often you might have to characterize your device to determine the location of specific attack points of interestplot trace 0 in red, and 4-6 in blue.</li><li>''Traces per Attack'' allows you to use only See a subset full list of capture traces possible commands on each attack. Or if you have for example 1000 traces, you could average the results of attacking 50 traces over 200 attack runspage [[Plotting_Widget]].</li><li>''Reporting Interval'' is how often data is generated. A smaller interval generates more useful output data, but greatly increases computational complexity (e.g. slows down attack). If you only care about attacking the system, the reporting interval can be set to the number of traces. In which case the attack runs completely, and you get the results. For this tutorial you can set to a smaller number (such as 5).</li></ol>
