About Block Replacements

Using the Simulink Design Verifier software, you can define rules to replace blocks automatically in your model. For example, you can work around a block that is incompatible with the software by creating a rule that replaces an unsupported Simulink block in your model with a supported block that is functionally equivalent. Or, you can customize blocks for analysis by creating a rule that adds constraints or objectives to particular blocks in your model.

When performing block replacements, the software copies your model and replaces blocks in the copy, without altering your original model. In this way, you can easily customize a model for analysis.

The Simulink Design Verifier software replaces blocks automatically in a model using:

• Libraries of replacement blocks

• Rules that define which blocks to replace and under what conditions

You replace any block with any built-in block, library block, or subsystem.

Block replacements are extensible, allowing you to define your own libraries of replacement blocks and custom block replacement rules. Use this capability if you need to:

• Work around an incompatibility, such as the presence of unsupported blocks in your model.

• Customize a block for analysis, such as adding constraints to its input signals, objectives to its output signals, or eliminating the contents of a subsystem or Model block to simplify your analysis.

Note   You can use automatic stubbing as an alternative to block replacements. Automatic stubbing replaces unsupported blocks with elements that have the same interface. For more information, see Handling Incompatibilities with Automatic Stubbing.
