New features and changes introduced in this version are:

• Changed Source Dialog Box Behavior

• Changed Model Explorer Source Behavior

• Affected Blocks

• Model Load Warnings

In this release, Simulink software no longer provides the user with the ability to change the values of source block parameters through either a dialog box or the Model Explorer while a simulation is running.

*Changes described in this section reflect Simulink software reprogramming implemented to comply with a court decision regarding patent litigation.

Changed Source Dialog Box Behavior

In this release, opening the dialog box of a source block with tunable parameters causes a running simulation to pause. While the simulation is paused, you can edit the parameter values displayed on the dialog box. However, you must close the dialog box to have the changes take effect and allow the simulation to continue. Similarly, starting a simulation causes any open dialog boxes associated with source blocks with tunable parameters to close.

Since you can no longer change source block parameters while a simulation is running, this release removes the Apply button from the dialog boxes of source blocks.

Note   In this release, as in previous releases, if you enable the Inline parameters option, Simulink software does not pause the simulation when you open a source block's dialog box because all of the parameter fields are disabled and can be viewed but cannot be changed.

Changed Model Explorer Source Behavior

In this release, the parameter fields in both the list view and the dialog pane of the Model Explorer have been disabled and the Apply button has been removed for source blocks with tunable parameters while a simulation is running. As a result, you can no longer use the Model Explorer to change source block parameters while a simulation is running.

Affected Blocks

Blocks affected are all source blocks with tunable parameters, including the following blocks.

• Simulink source blocks, including

  • Band-Limited White Noise

  • Chirp Signal

  • Constant

  • Pulse Generator

  • Ramp

  • Random Number

  • Repeating Sequence

  • Signal Generator

  • Sine Wave

  • Step

  • Uniform Random Number

• User-developed masked subsystem blocks that have one or more tunable parameters and one or more output ports, but no input ports.

• S-Function and M-file (level 2) S-Function blocks that have one or more tunable parameters and one or more output ports but no input ports.

• Source blocks in other MathWorks products, including:

  • CDMA Reference Blockset product

  • Communications Blockset product

  • Embedded Target for TI's C6000™ DSP

  • Signal Processing Blockset product (formerly DSP Blockset)

  • Simulink^® Fixed Point™ product (formerly Fixed-Point Blockset)

  • System Identification Toolbox™ product

  • xPC Target™ product

  • xPC TargetBox^® product

  See the release notes for each product for a list of that product's source blocks affected by the changes in this release.

Model Load Warnings

Compatibility Considerations

If you open a model in Simulink 6.0 that was created or saved with Simulink 6.1, Simulink 6.0 displays warnings that the following parameters are undefined:

• StrictBusMsg

• MdlSubVersion

Depending on the model, Simulink 6.0 may also display a warning that the parameter BusObject is not defined. You can safely ignore these warnings.
