Signal Tracing

functions instead of using the xPC Target graphical user interface. This

procedure assumes that you have assigned

tg to the appropriate target PC.

After you create and download the target application, you can view output

signals.

Using the MATLAB interface, you can trace signals w ith

• Host or target scopes (see “Signal Tracing with the MATLAB Interface and

Target Scopes” o n page 3-41 for a description of with target scopes)

• File scopes (see “Signal Tracing w ith the M ATL AB Interface and File

Scopes” on page 3-45)

You must stop the scope before adding or removing signals from the scope.

Signal Tracing with the MATLAB Interface and Target Scopes

This procedure uses the Simulink model xpcosc.mdl as an example, and

assumes you have built the target applicatio n for this model. It describes how

to trace signals with target scopes.

1 Start running your target application. Type any of

+tg

tg.start

start(tg)

The t arget PC displ ays the following message.

System: execution started (sample time: 0.0000250)

2 To get a list of signals, type either

set(tg, 'ShowSignals', 'on')
