Creating a Model (Using Simulink)

Using Simulink

Signal Properties Dialog Box

The Signal Properties dialog box lets you view and edit signal properties.

The dialog box includes the following controls.

Signal name

Name of signal.

Show propagated signals

Note This option appears only for signals that originate from a virtual block.

Show propagated signal names. You can select one of the following options:

Option
Description

off
Do not display signals represented by a virtual signal in the signal's label.

on
Display the virtual and nonvirtual signals represented by a virtual signal in the signal's label. For example, suppose that virtual signal s1 represents a nonvirtual signal s2 and a virtual signal s3. If this option is selected, s1's label is s1<s2, s3>.

all
Display all the nonvirtual signals that a virtual signal represents either directly or indirectly. For example, suppose that virtual signal s1 represents a nonvirtual signal s2 and a virtual signal s3 and virtual signal s3 represents nonvirtual signals s4 and s5. If this option is selected, s1's label is s1<s2,s4,s5>.

Option	Description
`off`	Do not display signals represented by a virtual signal in the signal's label.
`on`	Display the virtual and nonvirtual signals represented by a virtual signal in the signal's label. For example, suppose that virtual signal `s1` represents a nonvirtual signal `s2` and a virtual signal `s3`. If this option is selected, `s1`'s label is `s1<s2, s3>`.
`all`	Display all the nonvirtual signals that a virtual signal represents either directly or indirectly. For example, suppose that virtual signal `s1` represents a nonvirtual signal `s2` and a virtual signal `s3` and virtual signal `s3` represents nonvirtual signals `s4` and `s5`. If this option is selected, `s1`'s label is `s1<s2,s4,s5>`.

Description

Enter a description of the signal in this field.

Document link

Enter a MATLAB expression in the field that displays documentation for the signal. To display the documentation, click "Document Link." For example, entering the expression

web(['file:///' which('foo_signal.html')])

in the field causes MATLAB's default Web browser to display foo_signal.html when you click the field's label.

Displayable (Test Point)

Check this option to indicate that the signal can be displayed during simulation.

Note The next two controls set properties used by the Real-Time Workshop to generate code from the model. You can ignore them if you are not going to generate code from the model.

RTW storage class

Select the storage class of this signal from the list. See the Real-Time Workshop User's Guide for an explanation of the listed options.

RTW storage type qualifier

Select the storage type of this signal from the list. See the Real-Time Workshop User's Guide for more information.
