Sample output from the target code show, with the SimpleTimer model compiled in Debug
configuration, and Metrix enabled, is as follows. Note that the SimpleTimer output is
missing. Note from the CoMET simulation statistics, beginning "Total Instructions
Executed", that the simulation takes much longer.
