Autosar is using c code to implementation. In C language, I can define my own data structure with typedef struct. If I want to use InterRunnableVariable in AUTOSAR, is it possible to define InterRunnableVariable data type with my own C data structure in design level? (Let say, I use SystemDesk from dspace for designing)
Yes it is. Please check the Software Component Template (http://www.autosar.org/fileadmin/files/releases/4-2/methodology-and-templates/templates/standard/AUTOSAR_TPS_SoftwareComponentTemplate.pdf) to see how ImplementationDataTypes of category STRUCTURE can be modeled (some examples are given there too).
