• Production Hardware Characteristics
• Including Symbols and Greek Letters in Block Diagrams
• True Color Support
• Print Details
• Boolean Logic Signals
• Model Discretizer

Enhanced Mask Editor

This release introduces changes to the Mask Editor designed to improve usability. Changes include

• Block parameter information moves from the Initialization pane to a new pane entitled Parameters.
• The Parameters pane allows you to specify a callback function to be called when the value of a parameter changes.
• The Parameters pane allows you to specify via check boxes whether a parameter is visible on the masked block's dialog box and whether a parameter is tunable.
• The Icon pane provides a list of examples of all the types of drawing commands that can be used to draw the block's icon.

See Creating Masked Subsystems in the online Simulink documentation for more information.

Including Symbols and Greek Letters in Block Diagrams

This release allows you to include symbols, Greek letters, and other formatting in annotations, masked subsystem port labels, and masked subsystem icon text. You do this by including TeX formatting commands in the annotation, port label, or icon text.

Production Hardware Characteristics

Production hardware characteristics is a new setting on the Advanced pane of the Simulation parameters dialog box. This setting, intended for use in modeling, simulating, and generating code for digital systems, allows you to specify the sizes of the data types supported by the system being modeled. Simulink uses this information to automate the choice of data types for signals output by some blocks. See The Advanced Pane" for more information.

True Color Support

This release allows you to use any color supported by your system as the foreground or background colors of a block diagram. See Specifying Block Diagram Colors in the online documentation for more information.

Print Details

This command generates an HTML report detailing the contents of the currently selected model (see Generating a Model Report in the online documentation for more information).

Boolean Logic Signals

In previous releases, the Boolean logic signals optimization was off by default for new models (see Optimizations in the online Simulink documentation for a description of this option). In the current release, the optimization is on by default for new models. This change does not affect existing models.

Model Discretizer

The Model Discretizer tool selectively replaces continuous Simulink blocks with discrete equivalents. Discretization is critical in digital controller design for dynamic systems and for hardware in the loop simulations. You can use this tool to prepare continuous models for use with the Real-Time Workshop Embedded Coder, which supports only discrete blocks. See Model Discretizer in the online documentation for more information.
