How do I create AUTOSAR CompuMethods of ”BITFIELD_TEXTTABLE“ and "SCALE_LIN​EAR_AND_TE​XTABLE" categories?

I am working on an AUTOSAR model, and I would like to create CompuMethods of ”BITFIELD_TEXTTABLE“ and "SCALE_LINEAR_AND_TEXTABLE" categories, add Simulink Data Types to these CompuMethods, and generate model codes and ARXMLs. How can I create and use such CompuMethods?

As of MATLAB R2023b, you can create CompuMethods of ”BITFIELD_TEXTTABLE“ and "SCALE_LINEAR_AND_TEXTABLE" and associate them with Simulink Data Types via the Round-Trip Workflow. That is, you first use the XML description generated by an AUTOSAR authoring tool to import an AUTOSAR software component into a model. Later, you generate AUTOSAR C and XML code from the model.

When you have the ARXML available, you can use the following codes to import ARXML and update the AUTOSAR properties in the model, so that the CompuMethod from ARXML can show up within AUTOSAR Dicitionary:

ar = arxml.importer('MWExampleARXML.arxml');
ar.updateAUTOSARProperties(model);

You can then assign Simulink Data Types to the imported CompuMethod within AUTOSAR Dictionary.
