Modular real-time technology

The dSPACE SCALEXIO system is based on modular real-time technology for hardware-in-the-loop (HIL) and rapid control prototyping (RCP) projects. It provides high-performance real-time processors for demanding applications as well as comprehensive, precise, and fast I/O capabilities based on FPGA technology.

  • 支持基于处理器的仿真以及基于FPGA的仿真

    dSPACE 的 Electrical Power Systems Simulation Package 包可实时仿真 Simscape Power Systems™ (之前为SimPower­Systems™)中开发的电力系统模型。该软件包能提供多种方式,将在dSPACE HIL环境集成的电力系统™Simscape模型和基于FPGA处理器的仿真。


  • SPI和I2C的支持

    借助 SCALEXIO Serial Interface Solution,可以通过SCALEXIO 系统使用Serial Peripheral Interface (SPI)和Inter-Integrated Circuit (I2C)总线。



    新型的SCALEXIO LabBox为多达18个 SCALEXIO I/O板卡提供插槽,使之成为迄今为止体积最小的dSPACE仿真器。 它与 SCALEXIO Processing Unit(作为计算节点)结合后,能让用户享有自己的桌面 HIL 仿真器。


  • 灵活的功能测试

    对于想要快速地测试新的控制器或软件功能,可灵活改变的,可定制化的小型硬件在环仿真器是理想之选。dSPACE 推出的新型 SCALEXIO LabBox正是这样的一套系统。


  • 成功应用

    dSPACE 两年前推出的 SCALEXIO 硬件在环 (HIL) 测试系统已在无数的客户项目中发挥了重要作用。如今,这些产品已经在全球各个国家/地区广泛应用,包括中国、法国、德国、意大利、日本、英国和美国等。


  • SCALEXIO 五年历程 – 回顾过去,展望未来

    2011 年,dSPACE 隆重推出了全新的硬件在环 (HIL) 系统 SCALEXIO。dSPACE HIL 测试系统负责人 Tino Schulze介绍了该系统的开发过程和未来计划。


  • 如何充分利用HIL系统

    在这次免费的网络研讨会,dSPACE将介绍如何快速优化HIL系统的功能,达到 ISO-26262的标准,执行基于需求的测试,以及实现全天候不间断的HIL操作。


Application Areas

The dSPACE SCALEXIO product line comprises flexible and modular systems in various sizes for hardware-in-the-loop (HIL) and rapid control prototyping (RCP) projects in various industries such as automotive, automation, aerospace, medical, transportation, or research. Its powerful real-time technology and comprehensive bus support are ideally suited for the demanding applications of today and tomorrow, which include advanced driver assistance systems (ADAS), autonomous driving, electromobility, and increasing network communication. 

Key Benefits

  • Scalable to any required size
  • Large distributed system setups
  • High-performance processor technology for fast calculation of large and complex models.
  • Comprehensive, precise, and fast I/O capabilities based on FPGA technology.
  • High bandwidth and low jitter for best closed-loop performance based on the IOCNET backbone that is optimized for real-time applications
  • Flexible software-based system configuration
  • Support of Functional Mock-up Interface (FMI)

SCALEXIO provides two types of real-time processing platforms:

  • The SCALEXIO Processing Unit is based on an industrial PC that can be used within a SCALEXIO Rack System or as a stand-alone desktop version. It is suited for applications with high performance requirements.
  • The SCALEXIO DS6001 Processor Board is a real-time platform developed by dSPACE. Thanks to its compact size, it can be integrated in a SCALEXIO LabBox. The DS6001 is suited for applications that require fast closed-loop rates or high I/O bandwidth.

Both real-time platforms provide a similar architecture. For example, they both offer a host interface and I/O interface. They also have an angular processing unit (APU) functionality for highly precise angle-based simulation to measure injection and ignition signals, for example. With these real-time platforms up to six independent APUs can be used.

Multicore Support for Large Models

Depending on the processor, large, complex simulation models can be distributed across several processor cores to ensure that they are computed in real time. A configuration software is used to distribute model parts to the cores and to configure the communication behavior, the simulation hardware, and the model connections.

Multiprocessor Support for Large Systems

Multiprocessor support means that all SCALEXIO systems can be interconnected to increase computational power. To provide large bandwidths, SCALEXIO processing hardware can be interconnected via IOCNET. To ensure convenient modeling, you can either use only one overall project in ConfigurationDesk or work with multiple projects when working with more than one team, for example.

Host Interface

Communication with the host PC is carried out via Gigabit Ethernet, so the SCALEXIO system can be used in any company network. When more than two processing hardware components are used, they are interconnected via an Ethernet switch to ensure communication with the host PC. The IP address for the connection can be assigned via a DHCP server or stored on the SCALEXIO system itself.

SCALEXIO offers three types of I/O boards for its different enclosure types (SCALEXIO LabBox and SCALEXIO off-the-shelf rack system). Local signal processing on these boards helps take some of the load off the real-time processor to ensure highest real-time performance of the SCALEXIO systems. The installation and configuration is similar for all hardware types, so there is very little training effort.

All SCALEXIO I/O hardware shares the following characteristics:

  • Local signal preprocessing on I/O boards to take some of the load off the real-time processor
  • Connection to the processing unit via an IOCNET interface
  • Fully software-configurable
  • Similar installation and configuration processes, so very little training effort is necessary

As a laboratory system, the SCALEXIO LabBox is ideally suited for a wide range of applications, such as RCP or DAQ projects, function testing, test bench control, and as a base system for HIL setups. The compact chassis fits on an office desk and offers space for up to 18 SCALEXIO I/O boards, which can be easily changed by the user.

SCALEXIO Rack System

For ECU tests, the SCALEXIO off-the-shelf rack systems provide sufficient space for MultiCompact units, HighFlex boards, and SCALEXIO I/O boards. The SCALEXIO for HIL applications comes with nine and twelve height units (U). It is the ideal tool for testing single ECUs.

SCALEXIO Customized Rack System

The customized SCALEXIO simulator is tailored to customer-specific requirements. It provides maximum flexibility and can be expanded easily. Its typical fields of application include complex tests of networked ECUs as well as tests that include electronic loads and complete virtual vehicles.

Test Benches

ECUs that cannot be accessed via their electrical interfaces for testing require highly dynamic test benches. dSPACE offers turn-key projects for test benches that let you use mechanical loads and physically stimulated ECUs.
