Modeling system architecture and generating virtual ECUs

SystemDesk is a system architecture tool that provides sophisticated and extensive support for modeling AUTOSAR architectures and systems for application software. Additionally, SystemDesk generates virtual ECUs (V-ECUs) out of the application software. The V-ECUs can be used as units under test with the dSPACE simulation platforms, such as the PC-based simulation platform VEOS for validating the ECU software.

As a system architecture tool, it provides sophisticated and extensive support for modeling AUTOSAR architectures and systems for application software. Comprehensive graphical support facilitates the first use but also enables efficient and error-reduced working in large-scale projects.

The second application area creating virtual ECUs (V-ECUs) for validating ECU software at an early development stage. V-ECUs contain series code for the functionalities to be tested, either at application level only or also including basic software. They can then be used as unit under test with the dSPACE simulation platforms, such as the PC-based simulation platform VEOS.

  • Comprehensive validation of the software architecture model for direct feedback in case of problems

Working with SystemDesk

SystemDesk supports the development process with numerous features for intuitive working:

  • AUTOSAR-Compliant Modeling
    Use SystemDesk’s authoring capabilities to create and edit software architecture and system descriptions according to the AUTOSAR standard.
  • Generation of Virtual ECUs for Simulation
    Use SystemDesk to generate virtual ECUs (V-ECUs) that include dSPACE's or your own basic software modules to get a realistic representation of the real ECU. The V-ECUs are based on AUTOSAR- or non-AUTOSAR-compliant code. Simulate the V-ECU with VEOS to validate your software in a PC-based simulation.
  • Dialogs and Diagrams
    For an easy and efficient capture and configuration of common AUTOSAR data, SystemDesk offers convenient, preconfigured dialogs. Additionally, special diagrams of the software architecture and system elements help keep an overview of your model.
  • Data Exchange with TargetLink
    You can exchange data seamlessly between SystemDesk and dSPACE's production code generator, TargetLink. This gives you a secure process for including the actual functionality in the software architecture in a model-based development environment.
  • Project Validation
    Use SystemDesk’s validation functionality to ensure that your AUTOSAR architecture is complete and consistent before giving it to a project partner for basic software (BSW) configuration and before generating a V-ECU – and save time by finding problems as early as possible. You can define your own validation rules to also check compliance with company-specific project requirements.
  • Complete and Documented Tool API
    Use the open tool API to automate recurring design tasks and extend the features of SystemDesk according to project-specific requirements or even use it to create a completely automated tool chain for V-ECU generation.
  • Application Software and BSW Integration
    For testing the ECU software, you can either combine your application software with dSPACE basic software (BSW) modules or import your own BSW. Importing your own production BSW lets you test your basic software or functions that require realistic BSW input, such as diagnostics functions. If your test focus is the application software, using the dSPACE BSW is more convenient, as it is automatically generated and configured according to the systems requirements.
