DS2655 FPGA Base Board

SCALEXIO I/O board with user-programmable FPGA

The DS2655 provides a user-programmable FPGA and has been designed for applications that require very fast, high-resolution signal processing. It is ideal for implementing signal preprocessing and control algorithms, simulation models with fast sample rates or specific I/O interfaces to optimize support for processor applications. You can also transfer simulation models and control algorithms that normally run on the processor to the FPGA, in part or as a whole.  

Application Area 

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
  • Electric power industry applications
  • Power electronics simulation
  • Electric motor control development
  • Protocols
  • Power electronics control development

Together with dSPACE electronic load modules and/or the XSG Electric Components Library, the DS2655 extends the SCALEXIO system to a power hardware-in-the-loop system. The SCALEXIO EMH Solution and the Electrical Power Systems Simulation Package are also based on the DS2655. For FPGA-based control development, the DS2655 can be used together with the XSG AC Motor Control Library.

Key Benefits

The DS2655 is available in two versions of freely field-programmable gate arrays (FPGA):

  • The DS2655 7K160 includes a Xilinx® Kintex®-7 160T and is a cost-effective solution for smaller applications.
  • The DS2655 7K410 includes a Xilinx® Kintex®-7 410T with a large RAM, which makes it ideal for electric drive applications.

To include more I/O channels, you can connect up to five I/O modules to the board. Additionally, you can connect two DS2655 boards with the inter FPGA communication cable for direct data exchange between FPGA stacks.

Programming the FPGA

Applications for the DS2655 FPGA are modeled with the Xilinx® System Generator, RTI FPGA Programming Blockset, and the related dSPACE XSG-based solutions. If required, you can react flexibly to new requirements, such as new interfaces or having to accelerate the execution of submodels. You can also test the program in offline simulation before implementing it on the real-time hardware. Using dSPACE ConfigurationDesk, you can download the programs to the FPGA.

I/O Modules

Two I/O modules are available to expand the I/O channels of the DS2655 FPGA Base Board: the DS2655M1 Multi-I/O Module and the DS2655M2 Digital I/O Module. Up to five I/O modules can be connected to the board, thus providing a flexible, customized channel set.
