Introduction
Signal tracing is the process of acquiring and visualizing signals w hile
running a target application. In its most basic sense, allows you to acquire
signal data and visualize it on the target PC or upload the signal data and
visualize it on the host PC while the target application is running.
Signal tracing diffe rs from sig nal logging. With signal logging you can only
look at signals after a run is finished and the log of the entire run is available.
For information on signal logging, see “Signal Logging ” on page 3-57.
Note xPC Target Explorer works with multidimensional signals in
column-major format.

The procedures in this topic use the model xpcosc.mdl as an example, and
assume you have created, downloaded, and started the target application
on the target PC.
