Add Simulink alias type to Architectural Data section of Simulink data dictionary

Since R2023b



    dataType = addAliasType(archDataObj,dataTypeName) adds a Simulink.AliasType specified by dataTypeName to archDataObj.


    dataType = addAliasType(archDataObj,dataTypeName,BaseType=baseType) adds a Simulink.AliasType specified by dataTypeName using the specified base type to archDataObj.

    To add a Simulink.AliasType with a specified name to the data dictionary, use the addAliasType function. For an example that shows more of the workflow for related functions, see Create Architectural Data Object and Use It to Configure Architectural Data.

    Create or open a data dictionary. This example uses a previously created data dictionary MyInterfaces.sldd.

    dictName = "MyInterfaces.sldd";
    archDataObj =;

    Add alias types using the addAliasType function. Specify the name, and base type using either input arguments of the function or the created alias type object.

    myAliasType1 = addAliasType(archDataObj,'aliasType',BaseType="single");
    myAliasType1.Name = "myAliasType1";
    myAliasType1.BaseType = 'fixdt(1,32,16)';
    myAliasType2 = addAliasType(archDataObj,'myAliasType2');

    You can use alias type objects as the base types of other objects.

    myAliasType2.BaseType = myAliasType1;

    Input Arguments

    Architectural Data object, specified by Simulink.dictionary.ArchitecturalData object.

    DataType definition name in the DataTypes property array of archDataObj, specified as a character vector or a string scalar.

    Example: "airSpeed"

    Base data type that this alias renames, specified as a character vector or string scalar. You can specify the name of a standard data type, such as "uint32" or "single", or the name of a custom data type, such as the name of another Simulink.AliasType object, or the name of an enumeration.

    Example: BaseType="uint32"

    Output Arguments

    Alias type object, returned as a Simulink.dictionary.archdata.AliasType object.
