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.

Attributes

• 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
