• Automatic implementation of MATLAB^®/Simulink^®/Stateflow^® models on dSPACE hardware
• Automatic code generation
• Graphically supported I/O configuration via comprehensive Simulink block libraries
• Support for model referencing for RTI single processor models¹⁾

Application Areas
No matter whether you are performing rapid control prototyping or hardware-in-the-loop simulation: Real-Time Interface (RTI) is the link between dSPACE hardware and the development software MATLAB/Simulink/Stateflow from The MathWorks.

Key Benefits
RTI lets you concentrate fully on the actual design process and carry out fast design iterations. It extends Real-Time Workshop^® and Stateflow Coder^® (C code generators) for the seamless, automatic implementation of your Simulink and Stateflow models on the real-time hardware. The implementation time is greatly reduced.

Working with RTI
To connect your model to a dSPACE I/O board, just drag & drop the I/O module from the RTI block library and then connect it to the Simulink blocks. All settings, such as parameterization, are available by clicking on the appropriate blocks. Real-Time Workshop generates the model code while RTI provides blocks that implement the I/O capabilities of dSPACE systems in your Simulink models. Your real-time model is compiled, downloaded, and started automatically on your real-time hardware, without you having to write a single line of code.

Comprehensive Functionalities
RTI handles any kind of continuous-time, discrete-time, hybrid, and multirate system. Depending on the I/O hardware, different channels of the same I/O board can be used with different sample rates, and even in different subsystems. RTI supports asynchronous events and lets you set task priorities and task overrun strategies for the execution of the interrupt-driven subsystems. It also supports time-triggered tasks and timetables, which allow you to implement tasks and groups of tasks with variable or predefined delay times in relation to an associated trigger event. This makes task handling in your model very flexible.

¹⁾ Support for model referencing for RTI single processor models
The principle of model referencing is that models stored as separate files can be included in other models. This facilitates a flexible and modular development process plus incremental loading and code generation. dSPACE will offer limited support for model referencing with RTI, applicable to RTI single processor models.
Please note: As of December 2007, the support for model referencing is still under development and therefore subject to change. dSPACE reserves the right to alter the specifications at any time without notice. Please contact dSPACE for information on features and limitations.
