Merge data elements from multiple ASAP2 (A2L) files

Since R2023a



    mergeObj = coder.asap2.merge(modelName,a2lFilePath) merges the data elements from the source A2L file specified in the a2lFilePath with the ECU descriptor object of Simulink model modelName. You can merge more than one A2L files with the Simulink model.


    To use the coder.asap2.merge function, Vehicle Network Toolbox™ is required.


    collapse all

    Open a model and build it. The model can be dummy without any data elements.


    Call the function by specifying the A2L files to be merged.

    mergeObj = coder.asap2.merge("ModelName1",{"ASAP2File1.a2l","ASAP2File2.a2l"});

    The mergeObj descriptor object for the model ModelName1 contains the data elements from the ASAP2 files ASAP2File1 and ASAP2File2.

    Export the ASAP2 file for the model by using the command.


    Input Arguments

    collapse all

    Specify the Simulink model name. Generate code for the model before calling it for merge.

    Example: ModelName1

    Specify the path and name of the A2L file. If the A2L file is in the working directory,specify the file name.

    Example: folder/asap2FileName1.a2l

    Example: asap2FileName2.a2l

    Name-Value Arguments

    Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

    Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

    Example: MapFile='model.elf' updates the ECU description object of the model by containing debug mapping information from the model.elf file.

    Full path to a folder in which to place an exported A2L file.

    Example: Folder='/home/temp/prjct/'

    Name for the exported A2L file.

    Example: FileName='test_car'

    Name of the model symbol file that contains symbols of generated code. For example, the addresses of variables used in generated code.

    Example: MapFile='model.elf'

    A2L file format based on the ASAM MCD-2 MC standard defined by ASAM. There are multiple versions of the ASAM MCD-2 MC standard. Specify the version of A2L that you want.

    Example: Version='1.61' or Version='1.31'

    Generate the A2L file by including or excluding comments.

    Example: Comments=true

    Generate the A2L file by including or excluding A2ML and IF_DATA sections.

    Example: GenerateXCPInfo=true

    Custom model instance name in an A2L file. This argument is applicable only for AUTOSAR adaptive models.

    Example: ModelClassInstanceName='customObj' or ModelClassInstanceName='customNameSpace::customObj'

    Generate an A2L file by following indentation.

    Example: IndentFile=true

    Create a user base and customize the ASAP2 fields such as:

    • ASAP2FileName

    • ByteOrder

    • HeaderComment

    • ModParComment

    • ModCommonComment

    Example: CustomizationObject=obj

    Group the parameters and signals based on their properties.

    Example: CustomizeGroupsBy={'ARRAY','MAP'}

    Export record layouts of all the base data types to a file named RecordLayouts.a2l according to the version of the A2L file.

    Example: IncludeAllRecordLayouts=true

    Specify false to exclude elements that are part of the structure in the generated ASAP2 file.

    Example: SupportStructureElements=false

    Specify false to exclude 64-bit integers in the generated ASAP2 file.

    Example: Support64bitIntegers=false

    Specify a 32-bit integer value to specify additional address information in the ASAP2 file. By default, no additional address information is required.

    Example: EcuAddressExtension=4

    Generate the A2L file by including or excluding the AUTOSAR RTE elements.


    This option is applicable only for AUTOSAR classic models.

    Example: IncludeAutosarRteElements=true

    Save the preferences made and generate the ASAP2 file with the preferences updated such as including the comments, version of the ASAP2 file.

    Example: UseSavedSettings=false

    Specify true to include a default event list in the A2L file.

    Example: IncludeDefaultEventList=true

    Update the array layout to ROW_DIR or COL_DIR to view the array data in row wise or column wise.

    Example: ToggleArrayLayout=true

    Generate separate A2L files for compu methods and record layouts.


    This option is applicable for models with ERT - based system target files.

    Example: IncludeSharedElements=true

    Output Arguments

    collapse all

    ECU description object containing the data elements from the specified Simulink model and A2L file. Use the object with coder.asap2.export function to export the merged A2L file.
