Configuration and implementation software for dSPACE SCALEXIO hardware

ConfigurationDesk is an intuitive, graphical configuration and implementation tool, ideal for handling large HIL real-time applications based on SCALEXIO hardware, and for implementing behavior models and I/O function code on SCALEXIO hardware. ConfigurationDesk provides a clearly arranged overview of the external devices (e.g., ECUs), configured SCALEXIO channels, and the connected behavior models. 

  • Support of Simulink Implementation Containers

    ConfigurationDesk supports two approaches for working with Simulink models. Besides the direct import of MDL files, now Simulink implementation containers (SICs) can be generated. SICs contain the model C code and other artefacts, such as precompiled libraries and a model interface description.

  • Support for Functional Mock-up Units

    ConfigurationDesk supports the open Functional Mock-up Interface (FMI) standard. This enables the users to use different modeling approaches (e.g., based on physical modeling with Modelica) by using Functional Mock-up Units (FMUs). In HIL projects, FMUs can be integrated together with Simulink® models.

    The user workflow for importing and connecting FMUs to other model interfaces and to I/O is identical to the workflow for Simulink® models.

Application Fields

ConfigurationDesk is an intuitive, graphical configuration and implementation tool. It is ideal for handling HIL real-time applications, and for implementing behavior models and I/O function code on dSPACE SCALEXIO hardware. You can define and document external devices such as ECUs and loads, including their signal properties (descriptions, electrical properties, failure simulation settings, load settings). ConfigurationDesk displays user-defined views of the signal path between the ECU pins/load pins and the behavior model interfaces.

Key Benefits

With ConfigurationDesk, it is easy to implement the behavior model code (e.g., from MATLAB®/Simulink®/Simulink Coder™) and the I/O function code (from ConfigurationDesk) on the dSPACE SCALEXIO hardware. The entire build process for a real-time application is handled by ConfigurationDesk. Comprehensive documentation options and graphical displays give you great project transparency – a great advantage with large-scale HIL projects especially. You can assemble and configure the project-specific hardware offline as a "virtual system", in other words, as a purely software-based configuration. A real-time application can be executed for test runs even if parts of the necessary (and configured) I/O hardware are not physically available. In addition, you can generate a Microsoft® Excel® file with information on the wiring harness and on external devices.

Working with Simulink® Models

ConfigurationDesk provides two approaches for integrating Simulink® models:

  • Directly importing *.slx  and *.mdl files generated out of MATLAB®/Simulink®. The direct import approach is convenient if the Simulink® model has to be changed frequently, because in this approach the entire build process for a real-time application – including starting Simulink Coder – is handled automatically by ConfigurationDesk.
  • Generating Simulink implementation containers (SICs) out of MATLAB®/Simulink® and importing these SICs into ConfigurationDesk. Once the SICs are generated, they can be reused in different projects, without having to generate the C code again, thus saving time. Therefore, this approach is more favorable, when you want to reuse models for different projects or variants.

SICs are ZIP containers including the C code and other artifacts, such as precompiled libraries and a model interface description.
With the two ways of importing Simulink models, ConfigurationDesk always provides the best solution for your project needs and requirement.

Convenient Model Exchange

To make exchanging simulation models easy, dSPACE offers a Model Interface Package for Simulink® (MIPS) for generating Simulink implementation container (SIC) files.

With the free-of-charge MIPS, modeling experts can generate the (C code) SIC file with Simulink Coder, without needing a VEOS or ConfigurationDesk license. Out of their Simulink models and together with dSPACE Run-Time Target, they can generate code and create ZIP files that contain all the necessary code and artifacts for executing the models on different simulation platforms, such as VEOS and SCALEXIO.

Model integrators using SIC files do not have to generate code again for building the simulation. Using SICs therefore significantly reduces the amount of time needed for reusing the SICs in different projects.

Bus simulation
  • Import of bus configurations as bus configuration containers generated by the dSPACE Bus Manager

Large, complex models can be distributed across multiple processing units and processor cores to ensure the simulation runs in real time. Two different workflows are possible for this. The first is to use separate Simulink® models for each core and import them into ConfigurationDesk. Intermodel communication in this workflow is configured in ConfigurationDesk.

In the second workflow, there is one overall Simulink® model for the whole application, and a special Simulink block is used to specify which of its subsystems should be computed together on one core. The overall model is then automatically split into separate model files. Intermodel communication in this workflow is transferred from Simulink® to ConfigurationDesk.

One processor core executes one model. Several models are combined to processing-unit applications. These can be assigned to processing units in ConfigurationDesk, which automatically performs the core-to-model assignment within each unit.

One processing unit consists of several processor cores. One processor core in each processing unit is always reserved for communication with the host PC. The other cores can be used for behavior model calculation.
