  • Protocol development

In addition to custom programmable FPGA solutions, dSPACE offers an easy-to-use tool chain for model-based FPGA development in Simulink.

Key Benefits

The DS6651 Multi-I/O Module provides flexible interfaces for different position sensors, voltage measurement and generation as well as multipurpose digital I/O. Its channel set is ideally suited for highly dynamic control applications as well as for the high-fidelity simulation of electric drives and power electronics components.

The DS2655 FPGA Base Board has been designed for applications that require very fast, high-resolution signal processing, for example:

  • Hybrid vehicle applications
  • Electric drive applications
  • Processor-based electric drive simulation
  • Power hardware-in-the-loop applications
  • FPGA-based electric drive simulation
  • Energy technology applications
  • Power electronics simulation
  • Electric motor control development
  • Protocol development

Each dSPACE FPGA board can be coupled with up to five DS6651 modules to adapt the system to almost any use case. The modeling environment, extensive libraries for interfacing position sensors, and high-precision simulation of engines and power electronics components support the user and make getting started easy.
