Versatile system for HIL simulation
  • High channel and system flexibility
  • Completely software-configurable
  • Connectable to existing systems
  • NEW: Multicore and multiprocessor support
  • NEW: Support of Functional Mock-up Interface (FMI)
  • NEW: Support of virtual ECUs (V-ECUs)  

Application Area

dSPACE SCALEXIO1) is a very versatile hardware-in-the-loop (HIL) simulator that provides highly flexible channels, can be extended to any required size and is completely software-configurable. Its application range covers all test domains and vehicles, including the test of electronic control units (ECU) of electric drives.
Thanks to the SCALEXIO multiprocessing feature, the simulator can be coupled with existing SCALEXIO-based or DS100x-processor-board-based systems, allowing users to expand their existing test setups to meet growing project needs.

Key Benefits

  • Support of different workflows and user roles by separating I/O configuration, modeling and code generation
  • Test of different ECU variants and types on a single system with minimal configuration effort
  • Easily resized to fit specific test tasks because component test systems and network systems are both built with the same standardized hardware components and connections
  • Graphical configuration of channels
  • Use of virtual ECUs (V-ECUs) for HIL tests if the real ECU prototype is not available yet
  • Support of FMI

Hardware Concept

The SCALEXIO system is standardized and can be reused in all SCALEXIO system variations.
  • The core of a SCALEXIO system, the SCALEXIO Processing Unit, is based on commercially available components so that the processing technology is always up-to-date.
  • IOCNET, the scalable serial I/O network, provides the internal communication between the real-time processor and the I/O boards.
  • The SCALEXIO I/O units are specifically designed for typical ECU signals and offer:
  • Local signal preprocessing on I/O boards to relieve the load on the real-time processor
  • Integrated signal conditioning, as well as converters and parts of the electrical failure simulation
  • Similar installation and configuration processes, so very little time is spent on learning

Tests for Electric Motors

For testing ECUs for electric motors, which require short simulation cycles, fast calculations and quick I/O access, SCALEXIO offers the DS2655 FPGA Base Board with a freely programmable FPGA and a high level of I/O.
Used in combination with the XSG Electric Components Library, the DS2655 provides the fast reaction times required for simulating electrical machines in closed-loop operation with a controller. The FPGA computes parts of the simulation model for the electrical machine, e.g., from the XSG Electric Components Library.
You can also connect electronic load modules to the SCALEXIO system for different voltage ranges up to 800 V.  

HIL Simulation with Virtual ECUs

If an ECU's hardware prototype is not yet available for HIL testing, a virtual ECU (V-ECU) can be used with the SCALEXIO system instead. A V-ECU usually has the same software components as the final ECU and is generated using the SystemDesk V-ECU Generation Module. A V-ECU can be used either alone with the SCALEXIO or together with other V-ECUs or real ECUs. The combination of V-ECUs and ECUs in a network enables high-quality restbus simulation early in the development process. For using a V-ECU during HIL simulation, a SCALEXIO Real-Time license is needed. To configure V-ECUs, you can integrate them into a real-time application in ConfigurationDesk just like any other behavior model.

 1) Devices connected to the dSPACE HIL system, for example, electronic control units, can feed in high currents and high voltages (voltages over 60 V DC or 30 V ACRMS), which can be dangerous for the user. This can happen, for example, in systems for piezoelectric or hybrid applications. Such currents and voltages can result in property damage, personal injury, or death. Under all circumstances, you must observe all the safety precautions described in the documentation. Please contact dSPACE for additional safety-related equipment, such as electrically safe interface cables.
