The results of the two different power measurement tools are presented here. Along
with callibration results, we discover the power costs of TMR. It is also interesting
to note how sensitive power measurments are to design placement. Different placements
of each incrementer and counter design are used to emphasize this sensitivity.

In the results that follow, both the JPower and XPower tools were used to measure the
power of a design at frequencies ranging from 10 MHz to 70 MHz. The results of these measurements
are plotted in the graphs that follow. In each graph will usually be two pairs of
results. The lower red and blue line are the results for the design without the use of
TMR and the top red and blue lines are the results with TMR. All blue lines correspond to
JPower results, while all red lines correspond to XPower results.

Also included in the following results are tables which summarize important information for
each design. One of the pieces of information summarized is the slope of each line in the
graphs. This slope reports the increase in mA per 1 MHz for a given design. Another important
result is the TMR vs. non-TMR power ratio for a given design.
