DS2671 Bus Board

HighFlex board for interfacing to different bus systems

The DS2671 is used in a SCALEXIO hardware-in-the-loop simulator. With its freely configurable channels, the DS2671 can serve different bus systems for one ECU. The selected bus system can easily be changed from project to project because the channels can be completely configured by software.

Application Area

The DS2671 Bus Board is the interface between dSPACE Simulator and various bus systems. It has 4 multifunctional channels, each of which can support a bus system that is assigned to it by software.

The following buses and protocols are supported:

  • FlexRay
  • CAN (high-speed & fault-tolerant)
  • CAN FD
  • LIN/K-Line
  • RS232, RS422, RS485
  • TTL–based protocols

With its freely configurable channels, the DS2671 can serve different bus systems for one ECU. The selected bus system can easily be changed from project to project because the channels can be completely configured by software. Other bus systems and protocols can be added on request.

I/O Functionality

Each channel on the DS2671 has the circuit parts for supporting various bus systems, comprising an FPGA for the core and assorted transceivers. The bus system controllers, which include certified IP cores such as the Bosch E-Ray controller for FlexRay, are implemented on the bus FPGA.
To use a bus system or protocol that is not yet standardly supported, you can install the necessary transceiver in the channel's piggyback slot.
A different bus system can be used on each of the 4 channels on the DS2671.
