Innovative technology for HIL simulation

SCALEXIO, the main dSPACE hardware-in-the-loop (HIL) simulator, is available from small to large systems while providing very high processing power. It is configured entirely by software, which makes adapting to changing requirements flexible and easy. SCALEXIO can be coupled with other dSPACE HIL systems, such as Simulator Full-Size and Simulator Mid-Size, offering an easy way to update existing HIL systems.

  • Test 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.


  • New Processing Unit for Complex Model Computation

    dSPACE has introduced a new, more powerful processing unit for its SCALEXIO hardware-in-the-loop (HIL) system to address the growing need for more real-time computation capability, which is required for highly complex and high-fidelity simulation models.

  • SCALEXIO Is Evolving

    SCALEXIO, dSPACE’s new hardware-in-the-loop (HIL) system, has been expanding since its launch in 2011. The latest version helps users build especially large-scale test systems, including failure simulation, and makes it possible to use complex environment models.

Application Area

dSPACE SCALEXIO 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, 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 resizable 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 Functional Mock-up Interface (FMI) 

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 for all units, so very little time is spent on learning

The SCALEXIO I/O hardware comprises three hardware types, each specially designed for typical application needs. MultiCompact, HighFlex and SCALEXIO I/O hardware can be combined and extended to produce whatever system configuration you want. They have the following in common:

  • Local signal preprocessing on I/O boards to relieve the load on the real-time processor
  • Connection to the processing unit via an IOCNET interface
  • Completely software-configurable
  • Similar installation and configuration processes, so very little time is spent on learning


  • Large number of I/O channels for specific applications
  • Each channel has a fixed channel type, so the costs per channel are low.
  • Integrated signal conditioning and converters
  • Onboard Failure Insertion Unit (FIU)
