Author Block Masks
Simulink® enables you to create block masks. A mask is a custom user interface for a block.
By masking a block you encapsulate the block diagram to have its own parameter dialog box with its own block description, parameter prompts, and help texts.
You can mask an independent custom block that you can reuse as unique blocks like those defined in Simulink.
To know about creating a block mask, see Create a Simple Mask.

A mask can contain parameters that accept user input values. - Share Parameter Constraints Across Multiple Block Masks
This example shows how to create a parameter constraint and share it across masks of different blocks in the same model or different models. - Validate Input and Output Port Signals Using Port Constraints
You can validate compile-time signal attributes on the input and output ports of a masked block by using port constraints. - Validate Port Signals Among Ports of the Same Masked Block
This example shows how to create cross port constraints to validate compile-time signal attributes among ports of the same masked block. - Share Port Constraints Across Multiple Masked Blocks
This example shows how to create a port constraint and share it across masks of different blocks in the same model or different models. - Author Parameter and Port Constraints Using Standalone Constraint Manager
When creating masks for Simulink blocks, there are specific constraints and considerations related to parameters and ports. - Promote Block Parameters on a Mask
Blocks and subsystems can have multiple parameters associated with them. - Specify Data Types for an Edit Parameter Using Data Type Parameter
You can specify the acceptable data types for a mask edit parameter with a data type parameter. - Pass Values to Blocks Under the Mask

Promote Block Parameters on a Mask
Blocks and subsystems can have multiple parameters associated with them. Block masks allow you to expose one or more of these parameters while hiding others from view. You can promote any underlying parameter of a block either to a block mask or to a subsystem mask. For any subsystem, you have a single view of all the nested blocks, the block parameters, and internal parameters. You can click any node to access any promotable parameter within the nested blocks. By promoting parameters from the block dialog box to the mask you can:
Tune Mask Enumeration Parameters - Popup and Radio Button
Reference external enumeration file to assign numerical values to popup parameter.
Organize Mask Initialization and Callbacks in a MATLAB File
You can organize mask initialization and mask callback code in a separate MATLAB® class file. By using a separate MATLAB file you can:
Validate Port Signals Among Ports of the Same Masked Block
Create cross port constraints to validate compile-time signal attributes among ports of the same masked block. For example, you can set a constraint among the input and output port signals of the masked block to have the same data type. The rules for the cross port constraints are predefined. The available rules are Same Data Type and Same Dimension. Additionally, you can also set parameter conditions. Each port in the masked block is identified by port identifiers. The cross port constraint association is done through port identifiers.
