dSPACE rolls scalable HiL simulator system

March 08, 2011 // By Christoph Hammerschmidt
At the embedded world Exhibition&Conference 2011, mechatronic systems design tool vendor dSPACE GmbH presented its new system of hardware-in-the-loop (HiL) simulators, dubbed Scalexio. Along with the Scalexio, the company introduced a new embedded PC, designed as an extension to the company's MicroAutoBox compact prototyping system.

The Scalexio technology introduces new hardware and software architectures that fulfill changed users' requirements for HiL projects. The system's component-based design enables users to scale their systems to almost any desired size. The system is software-configurable can be used in different test tasks. Scalexio's hardware and software concept supports the structuring of tasks which has steadily increased in HiL testing departments over the last few years. For example, hardware configuration and plant modeling are separate tasks.

Different ECU variants and types can be tested on the same system – for engine or transmission, singly or combined, and so on. Specifications can changed at any point in time, and new components can also be tested for vehicle platforms that are already running.

Scalexio can be sized to fit specific test tasks. Component test systems and network systems are both built with the same hardware components. This allows users to take subsystems from a network system and use them to run component tests.


Scalable and flexible, the Scalexio HiL simulator is designed for next-gen automotive electronics systems.

Since the system has been designed using a standardized component design and standardized connections, hardware modules can be installed in any slot. All the channels are configured by means of graphical software, so complete system documentation is available automatically. Thus, not only the initial system implementation, but also later modifications and redesigns, can be performed.

Also introduced at embedded world is the MicroAutoBox Embedded PC, an optional extension for the MicroAutoBox compact prototyping system that is tailored to the needs of current development trends. The Embedded PC provides an Intel Atom processor (1.6 GHz), 2 GB RAM, a 2.5" SATA hard or solid state disk drive and numerous interfaces for new application options.   

Aims at telematics, driver assistant systems and image processing in automotive electronics: The MicroAutoBox extension.
