How To invoke a model's template from another model in xpand for AUTOSAR

Question

I've been trying to develop an AUTOSAR 4.2.1 module to generate code using Xpand/Xtend. I'm using artext demonstrator 1.6.0. But my query is that the concept of defining a variation point is not found in the PDF(ECUConfigurationParameters.arxml) when I create a new Ecu platform project in the demonstrator (or maybe I'm not familiar with finding out how).

By default I'm able to fetch parameter values from an arxml. But when there is more than one value for a parameter which is defined in a different post build variant condition, I'm getting only the first value. For example, if the arxml contains this

<ECUC-NUMERICAL-PARAM-VALUE>
<DEFINITION-REF DEST="ECUC-BOOLEAN-PARAM-DEF"> /AUTOSAR/EcucDefs/Com/ComConfig/ComIPdu/ComIPduCancellationSuppo rt</DEFINITION-REF>
<VARIATION-POINT>
<POST-BUILD-VARIANT-CONDITIONS>
<POST-BUILD-VARIANT-CONDITION>
<MATCHING-CRITERION-REF DEST="POST-BUILD-VARIANT-CRITERION">/EcucDemo/PostBuildConfigSet</MATCHING-CRITERION-REF>
<VALUE>1</VALUE>
</POST-BUILD-VARIANT-CONDITION>
</POST-BUILD-VARIANT-CONDITIONS>
</VARIATION-POINT>
<VALUE>1</VALUE>
</ECUC-NUMERICAL-PARAM-VALUE>
<ECUC-NUMERICAL-PARAM-VALUE>
<DEFINITION-REF DEST="ECUC-BOOLEAN-PARAM-DEF"> /AUTOSAR/EcucDefs/Com/ComConfig/ComIPdu/ComIPduCancellationSuppo rt</DEFINITION-REF>
<VARIATION-POINT>
<POST-BUILD-VARIANT-CONDITIONS>
<POST-BUILD-VARIANT-CONDITION>
<MATCHING-CRITERION-REF DEST="POST-BUILD-VARIANT-CRITERION">/EcucDemo/PostBuildConfigSet</MATCHING-CRITERION-REF>
<VALUE>2</VALUE>
</POST-BUILD-VARIANT-CONDITION>
</POST-BUILD-VARIANT-CONDITIONS>
</VARIATION-POINT>
<VALUE>0</VALUE>
</ECUC-NUMERICAL-PARAM-VALUE>

it gives me value as 'true' in Xpand if I do Com.ComConfig.ComIpdus.ComIPduCancellationSupport. I’m unable to access the second value ‘false’.

How may I proceed to fetch the parameter values based on the post-build variant conditions?

I'm trying to do the following:

«DEFINE Gen1 FOR varianthandling::VariationPoint»
    «EXPAND Gen1::GetThings»
«ENDDEFINE»

«DEFINE GenMain FOR AUTOSAR::EcucDefs::Com»
        «EXPAND Gen1 FOR varianthandling::VariationPoint»
«ENDDEFINE»

This gives me an error as 'Couldn't find definition ComOtherVarGen for type xpand2::Type'. How do I achieve the above? Please note that I am not trying to add/modify any functionality to the template of 'MainObj' so 'AROUND' is not what I'm looking for.

Any help is greatly appreciated.

The tool which you are using to create the model (which is created from the PDF file + EcuC Values file) must be able to build a model which is post-build compatible.

If you are sure, this being done- Then try the below method

Com.ComConfig.ComIpdus.ComIPduCancellationSupport changes to

<FOREACH Com.ComConfig.ComIpdus.ComIPduCancellationSupport AS ele>
<ele>
<ENDFOREACH>

or

Com.ComConfig.ComIpdus.ComIPduCancellationSupport.get(0) Com.ComConfig.ComIpdus.ComIPduCancellationSupport.get(1)
