<h2>Tracing</h2>
<p>Tracing is a way to record debugging information
that can be used during software development. With tracing, you can generate
detailed, low-level information about an application's execution in the target
device.</p>
<p>Examples of tracing are cases when messages are sent or received
from a component, when states change, when a certain function is entered or
exited, or anywhere else in the code where it is interesting to know if code
has been executed or not.</p>
<p>System level performance analysis and problem-solving
are often based on tracing. In your development team, a standard way to instrument
traces to your code (for example, using the same trace group for fatal error
tracing) can help in determining which level of traces should be activated.
</p>
<p>TraceViewer collects traces as follows:</p>
<ol>
<li>TraceViewer connects to the device according to the connection parameters
that can be defined on the <b>Preferences</b> page. </li>
<li>The tool then collects the traces for a specified purpose (for example,
during the testing of a certain component at the device side). </li>
<li>The traces are displayed on the Carbide IDE user interface.</li>
</ol>
<p><b>Note:</b> there is a distinction between <i>tracing</i> and <i>
logging</i> as general terms. Tracing is primarily for debugging and diagnostic
purposes, whereas logging writes records of program usage and is often a functional
requirement of a program.</p>
