SystemDesk supports the development of software architectures and distributed automotive electrics/electronics (E/E) systems. Such systems can be modeled according to the AUTOSAR standard. Existing communication matrix files can be imported in SystemDesk to specify network communication. When AUTOSAR software components are modeled or imported in SystemDesk, available ASAM MCD-2 MC (ASAP2) models can be imported as well. During generation of the AUTOSAR run-time environment (RTE) and virtual ECUs (V-ECUs), ASAP2 file generation is also performed for variables that are tagged for calibration and measurement according to the AUTOSAR concept. When V-ECUs are built, instances of the XCP service (XCP on Ethernet – TCP/IP) are implemented in the V-ECU code. Thus, the V-ECUs and variables described in the ASAM MCD-2 MC (ASAP2) files can be accessed during simulation.
