dSPACE’s SystemDesk version 2.0 lets users model and simulate software architectures and systems directly on a PC, allowing software functions to be tested and verified at the early stage of the development process. Graphic modeling in SystemDesk makes the development of complex electronic control unit (ECU) systems much easier. For automotive OEMs and Tier 1 suppliers that are pursuing AUTOSAR (AUTomotive Open System ARchitecture) compliant development, SystemDesk 2.0 supports both 2.1 and 3.0 AUTOSAR releases. Users are able to not only simulate individual software components but also verify the interaction of all software components, even in large-scale ECU networks. The measurement data is displayed graphically to make it easier to detect errors. Also, errors can be inserted to test the ECU's response to failures.
