TestCUBE2 – Simulation of ECUs

Configurable simulation of ECU diagnostics.

The ECU simulation TestCUBE2 is the counterpart for all cases of application in which an ECU is not yet (e.g. preparation of workshop tests) or no longer (e.g. tester regression test) available.
TestCUBE2 is a configurable hardware and software solution for simulating ECU diagnostics with real bus communication. With just one device, you can simulate several ECUs or even an entire vehicle at the same time.


Areas of Application

  • Preparation of workshop tests in Engineering, Testing, Manufacturing
  • Tester or production system release tests
  • Tester regression tests
  • Recording of CAN traces


  • Development of tests even before the ECU is available
  • Clear management of variants with archiving of simulation files
  • Fast familiarization enables easy handling
  • API interface enables automatic tester regression tests
  • High test quality thanks to various configuration possibilities
  • Best-case and worst-case tests
  • Modification and exchange of the simulation via programming interface
  • Complex sequences can be realized
  • Can run even without a PC



  • Simulation of several ECUs (CAN or K-line) with one device
  • Reliable response time behavior due to protocols being run directly on the interface
  • Automatic creation of the simulation from a CAN bus trace (*.asc/*.trc)
  • Residual bus simulation with import of CANdb file and database at symbolic level
  • High-performance interface with 32-bit PowerPC core (384MHz)
  • Supported buses: CAN, K-line
  • Supported protocols: UDS, KWP2000, TP2.0, J1939
  • Three analog inputs and three digital inputs/outputs
  • Adapter interface with banana jacks
  •  Influencing of communicationparameters (address, timings,...)

Creating Simulation Files

Usually, simulation files are created by manually editing the request and response messages in a convenient dialog. You thus have all the necessary freedom for the required test depth and scope in your application case. Alternatively, the simulation file can be generated automatically from an existing trace file – an incredible increase in efficiency particularly for regression tests. The simulation files of its predecessor TestCUBE can of course be imported.

Regression Tests

The great challenge in tester regression tests is the availability of the test environment – in the case of service testers, all vehicles in all variants. With TestCUBE2, you simply archive simulation files for all vehicle variants. In the regression test, you exchange the simulation files as required – in the case of automated tests via the programming interface. It really couldn’t be simpler!
