Fault insertion technology
Fault insertion, fault injection or FI solutions are used to apply the kinds of electrical errors most likely to occur in an application when something goes wrong.
Common fault insertion failure modes
Common failures that can occur, say in the event of ageing or an accident, are broken wires (open circuit) or wires shorted to the main supply (battery) or ground (chassis), due to shorts within a wiring harness. Occasionally wire-to-wire shorts can occur too.
Genix-based fault insertion solutions
It important that any fault insertion solution is itself robust and protected against damage and abuse, and should be considerably more capable than the system being tested.
For these reasons, our fault insertion solutions are fully protected against overload damage.
Verification of operation
Due to the robust hardware nature required for fault insertion, we often choose high current, high lifetime relays.
Genix fault insertion solutions can perform self-test functions prior to and post a series of tests, and can generate a hardware pass report for proof of valid test hardware operation.
Genix is a range of technologies for hardware-in-the-loop simulation that allow engineers to re-configure and scale test environments quickly as requirements change.
The LIN Switch board is a 16-channel configurable LIN grouping and switching board with fault insertion capabilities. Each board is compatible with add2 HIL racks.
The CAN Switch board is an 8-channel configurable low, medium or high-speed CAN switch board with fault insertion capabilities. Each board is compatible with add2 HIL racks.
