RTI FPGA Programming Blockset

Integrating FPGA models in dSPACE systems

The RTI FPGA Programming Blockset is a Simulink blockset for using a FPGA model created with a dSPACE system using the Xilinx® System Generator Blockset.

The end of life of the dSPACE PHS (peripheral high-speed) hardware for modular systems is planned for December 31, 2024. You can still buy the related products up to and including December 31, 2021. New Releases of dSPACE software will still support the dSPACE PHS hardware for modular systems until at least the end of 2023. Although the RTI FPGA Programming Blockset still supports PHS hardware, we advise against using the PHS hardware products in new projects. For new projects we recommend that you use SCALEXIO, the latest dSPACE technology for modular real-time systems.

Application Areas

The RTI FPGA Programming Blockset is a Simulink blockset for using a FPGA model created with a dSPACE system using the Xilinx® System Generator Blockset. It provides RTI blocks for implementing the interface between the FPGA mounted on a dSPACE board and its I/O, and the interface between the dSPACE FPGA board and its computation node.

The blockset can be used with the following dSPACE FPGA platforms, which provide user-programmable FPGAs:

  • DS2655 FPGA Base Board and its I/O modules.
  • DS6601/DS6602 FPGA Base Boards and their I/O modules.
  • MicroAutoBox II 1401/1511/1514 and 1401/1513/1514 extended with I/O modules.
  • MicroAutoBox III 1403/1511/1514 and 1403/1513/1514 extended with I/O modules.
  • MicroLabBox.

Typical application scenarios for rapid control prototyping (RCP) and hardware-in-the-loop (HIL) simulation are:

  • Projects in the automotives, industrial automation, medical engineering and aerospace industries
  • Signal preprocessing, adapting new interfaces, very fast control loops, designing and testing new concepts for electrified powertrains

Key Benefits

The dSPACE FPGA platforms provide a Xilinx® FPGA for which you can implement an application graphically by using Xilinx® System Generator in Simulink. The RTI FPGA Programming Blockset lets you integrate the resulting FPGA model in a Simulink model that runs on dSPACE hardware. The RTI FPGA Programming Blockset gives you a convenient way to connect the I/O board’s I/O driver components and to model the connection to a processor-based computation node (SCALEXIO processing hardware, MicroLabBox or MicroAutoBox). The data exchange supports fixed-point data types as well as floating-point data types. Thus, FPGA programming is seamlessly integrated into the Simulink environment. With the FPGA blockset, you can synthesize, build and program the FPGA or processor directly from Simulink for optimal convenience. During run time, you can access variables to trace or modify them, without having to modify the model.

Alternatively, the handcode interface lets you program the FPGA boards in VHSIC Hardware Description Language (VHDL) or Verilog.
