Parameter Tuning and Inlining Pa rameters
Note Opening a dialog box for a source block causes Simulink to pause. While
Simulink is paused, you can edit the parameter values. You must close the
dialog box to h av e the changes take effect and allow Simulink t o continue.
Parameter Tuning with xPC Tar get Explorer
The xPC Target software lets you change parameters in your target
application while it is running in real time. With these functions, you do not
need to set the Simulink interface to external mode, and you do not need to
connect the Simulink interface with the target application.
You can download parameters to the target application while it is running
or be tween runs. This feature lets you change parameters in your target
application without rebuilding the Simulink model. You cannot use xPC
Target Explorer to change tunable source block parameters while a simulation
is running.
After you download a target application to the target PC, you can change
block parameters u sing xPC Target Explorer. This procedure u ses the
Simulink model
xpcosc.mdl as an example, and assumes y ou have created
and downloaded the target application for that model.
1 In xPC Target Explorer, right-click the downloaded target application
node. For example,
xpcosc.
2 Select Start.
3 To get the lis t of parameters in th e target application, expand the Model
Hierarchy
node under the target application.
