FlexRay and CAN cluster emulation made easy

Cluster emulation with EB tresos Busmirror allows you to test  your ECU software during the implementation stage.  When you want to start up your ECU while the other ECUs in the network are not yet available, our cluster emulation solution mirrors the behavior of these missing ECUs.

In addition to testing the intended behavior, EB tresos Busmirror also emulates the responses to potential error situations, such as the sporadic absence of individual frames or the incorrect calculation of check sums.

Time critical functions can be carried out on EB interface hardware in real-time.  This allows you to emulate complex functions such as entire environment models or network management directly on the interface hardware, saving resources on your host system. With EB tresos Busmirror you can power up a FlexRay or CAN  network and configure the nodes to be emulated in a matter of minutes.

FlexRay and CAN cluster emulation in four steps

• Import a system configuration in the form of an
  

  • AUTOSAR system description
  
  
  • FIBEX file or
  
  
  • CANdb file.
  
  



• Select the network nodes/ECUs to be emulated


• Modify communication schedule


• Generate the configuration for the EB interface hardware

OEM specific cluster emulation

Our new extension package for EB tresos Busmirror allows you to emulate ECU clusters according to OEM specific requirements. Learn more about EB tresos Busmirror MAid for OEM.

EB tresos Busmirror Runtime

• All EB tresos Busmirror Runtime functions can be controlled via a Windows graphical user interface (EB tresos Inspector). This user interface is part of the delivery content.


• Broad interface API with functions for signal (coded and physical), PDU and frame access.


• Ensured consistent access to signal groups and PDUs


• Your own functions can be calculated in real-time directly on the EB hardware  by means of target user modules (TUMs).


• Useful TUM functions are included in the delivery content but can also be programmed by yourself.


• TUM functions can be executed asynchronous or synchronous execution of functions with respect to the FlexRay schedule.


• The TUM models can be configured during runtime, via a bidirectional data channel.


• Emulated nodes can be switched on or off during runtime


• The following drivers are included in the delivery:
  

  • National Instruments LabVIEW and LabVIEW RT (EB 5100 and EB 61×0)
  
  
  • LINUX and LINUX XENOMAI systems (EB 5100)
  
  
  • Windows (EB 5100 and EB 61×0)
  
  



• Our generic driver can easily be adapted to your a platform of your choice (EB 5100)


• Driver for the MATLAB/Simulink real-time hardware xPC available upon request


• Driver support for signal, signal group and frame access


• Signal access to coded and physical values


• Consistent access to signal groups


• Switch emulated frames and FlexRay nodes on and off


• Support for message based access to CAN data


• Support of up to 16 digital in- and output signals


• Independent FlexRay network start-up, when no other ECUs are connected to the network
