Developed by engineers for engineers
Novasom’s Validation systems – Fault Injection HIL are designed to address the real limitations of today’s HW validation tools for safety-critical electronic systems. Built on experience going back to the late 1990s, supporting Tier-1 suppliers and OEMs, our systems are used to validate Automotive ADAS, Railway, Avionics and Military devices and other safety-critical products against demanding functional safety standards such as ISO 26262, MIL-STD-461 or EN50155. With hardware fault injection for ISO 26262, you verify diagnostic coverage and validate your FMEDA with measured results on the real device, not with assumptions.
Novasom Industries Fault Injection HIL is listed among the fault injection tools in Wikipedia’s article on fault injection. It combines hardware-in-the-loop (HIL) testing with a bed-of-nails fixture on the PCBA, to produce the experimental evidence that ISO 26262 safety cases and FMEDA diagnostic coverage figures rely on.
Why real hardware fault Injection matters?
Modern safety-critical systems are increasingly very complex, requiring a redundant command chain. Validating them requires more than simulations or theoretical fault models , simply because the real world is much more complex and there we have to live.
While Software-in-the-Loop environments used at system level and FMEDA analyses are essential, they cannot fully represent real hardware behavior.
Hardware might fault in various ways, and we have to test it really to achieve safety goals.
To ensure reliable results, faults must be injected directly at hardware level, with accurate timing and electrical characteristics. Only real hardware fault injection can verify how the Device Under Test (DUT) truly reacts – both in hardware and software.
Designed for Large-Scale Validation
In automotive, railway, aerospace, and defense applications, validation complexity increases rapidly as the number of test points and fault cases grows. Traditional SIL platforms with hardware interface boards lack deterministic timing at microsecond level; introduce signal distortion or impedance mismatches; require high licensing costs and long setup times, while being limited in the pin count.
Our Fault Injection HIL systems are designed to work alongside these SIL platforms, not replace them – providing real hardware fault injection driven by message-based control.
- Simple Integration , we just receive serial commands via 232 or USB
- Easily integrated into existing SIL and functional safety toolchains like VtStudio or similar
- Because communication is message-based, the system integrates cleanly with any validation environment already in use.
- Totally expandable in pin count and injection types , adding a new custom board we can develop to fulfill your specific needs.
Hardware-Level Accuracy
High-level graphical programming tools and FPGA-based systems often struggle to guarantee deterministic fault delivery due to hardware-firmware pipeline delays. In contrast, our embedded architecture – without OS in pure RT – delivers precise, repeatable fault injection both at the connector and directly on the PCBA, on internal nodes that connector-level HIL cannot reach.
- Standards and Customization
Novasom HIL systems are standard products that can be customized with:
- Dedicated nail-bed fixtures
- Extension boards supporting CAN, Ethernet, I2C, and SPI
- They support validation activities aligned with standards such as:
- ISO 26262
- EN 50155
- MIL-STD-461
- All tests generate real, repeatable evidence, suitable for audits and certification processes.
- From Theory to Real Validation
Academic fault models often describe idealized scenarios that do not fully reflect real hardware behavior. Our approach enables validation of actual system behavior under real fault conditions, making FMEDA results and safety analyses truly meaningful: FMEDA validation and diagnostic coverage verification based on faults physically injected into the hardware.
We wil test it, really
Every hardware fault scenario suggested by your-our safety goals analysis can now be physically tested – verifying the complete system response.
- Engineering Support Included
Our team works directly with you to define the testing strategy and ensure successful implementation. Engineering expertise is included as part of the system offering , as to customize the specific needed nail bed or custom cards to support specific needs.
Seems bold, but we did it
and have been doing it for our clients since the late 1990s!
To give absolute reiliability to our fault injection system we’ve developed an architecture based on a backplane, a main CPU board that reads commands from a high-level C/C++ system , that shall drive the fmdea minded test, along with pure embedded I/O boards that are fully expandable and durable. This setup integrates seamlessly into a rugged mechanically defined nail bed for specific hardware-in-the-loop (HIL) testing needs.
Our custom HIL systems are complex and robustly built, but they’re invaluable. A fan-less , embedded architecture that will never fail a measure and will never need a reboot also working 27/7 . And it is lifetime warranty , call us and discover how
You’ll save time, effort, and cost by detecting and resolving hidden issues early, testing everything in every real condition at the HW ans SW level.
- Real-time measurement results
We’ve taken a crucial step forward, moving from statistical-theoretical analysis to real-world security measurements. Our Hardware-in-the-Loop (HIL) system provides real-time measurement results as your system operates, enabling your development team to identify faults and enhance resilience.
Yes, it’s feasible with our HIL system.
- 100% customized to your requirements
Our Hardware-in-the-Loop (HIL) system is designed to meet your exact needs, based on a COATS object. Built on years of testing experience, it can inject fault signals to reveal how complex products may fail, tracing failures and improving reliability at the design level. This is functional safety analysis made real—without requiring years of development time or added costs.
- Validate your project in all the scenarios and failure modes
When is custom hardware development the right choice? Not all systems interact seamlessly, and in a business relying on reliable operation, this can cause issues. Our Hardware-in-the-Loop (HIL) system is tailored to meet the specific circuit needs of your system, adapting precisely to your requirements—never the opposite.
- Made to measure
This isn’t a statistical method or new software; it’s a real hardware system that introduces faults directly at the component level. Our system can simulate issues like a resistor short or capacitor drift, providing practical, real-world electronics testing. Designed by engineers, for engineers, it delivers true-to-life diagnostics for robust product development.
