Simulink® Release Notes

Simulink 6.1 Release Notes

Changes from the Previous Release

In this release, Simulink 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 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 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
• Communications Blockset
• Embedded Target for TI C6000^TM DSP
• Signal Processing Blockset (formerly DSP Blockset)
• Simulink Fixed Point (formerly Fixed-Point Blockset)
