10.8 Profiler and Coverage functions
The main purpose of the profiler and coverage functions is to detect sections of programs (such as functions) that
cause bottlenecks and impair performance. The profiler and coverage functions are available only in simulator
mode.
10.8.1 Overview of functions
The profiler and coverage functions can be categorized into the following two groups.
(1) Measurement using simulator in GDB
Profile measurement : Measures the number of cycles consumed by each function and the number of
executions.
Code coverage measurement : Records whether each command was executed.
Measurement range : From Reset + Go to Break (excluding breaks in simulated I/O)
(2) Display of measurement data
The two tools, profiler result display executable file and coverage result display executable file, display
measurement data.

* Although the above tools are Windows applications, they are not designed for stand-alone operation. Note that
complete compatibility is not guaranteed under standalone operating conditions.
* A profiler measurement data file includes all profiler and coverage measurement information and is used by the
above two windows.
