Our HIL test systems typically include the following components:

  • Control PC for operating the HIL
  • Real-time system
  • SILVER ATENA I/O for signal conditioning and error simulations
  • Voltage supply for HIL system and UUT
  • Auto test box for automated self tests and for calibration (optional)
  • Test automation environment (optional)

Our HIL test systems are delivered with a CE marking.



  • Modular architecture
  • High flexibility and adaptability for modifications
  • Standard interfaces to various real-time systems
  • Short lead time from order to delivery
  • Short turnaround times on interface changes
  • Adaptation to various test derivatives
  • High reliability due to the reduced cable loom
  • Automatic self-test and self-calibration
  • Failure injection and break-out for each signal line of the equipment under test
  • Automated and sequential signal feedback loops by means of highly sensitive measuring devices
  • High precision combined with long-term stability

HIL systems for combustion engines

For the development, commissioning and acceptance of control units for combustion engines, SILVER ATENA develops hardware-in-the-loop (HIL) systems. The systems simulate and measure all required interfaces and thus can operate engine control units without real components.


Areas of application:

  • ECU hardware and software commissioning and acceptance tests
  • ECU system integration tests (closed loop, simulations with realistic combustion engine models))
  • ECU hardware qualification tests
  • ECU hardware production and end-of-line tests
  • Error simulation of I/Os and busses
  • Automated acceptance test for ECUs according to aviation standards
