UEI offers superior hardware-in-the-loop (HIL) I/O for your control, test and monitoring simulations. With solutions designed for aerospace, military, oil/gas, space and more, our robust and flexible HIL offerings ensure application success. We focus on exactly what you need -- from software integration (SIMULINK to C), hardware I/O (avionics, simulated synchro, LVDT, RTD, TC, etc), to signal routing (simulated, real or fault signals) to the device under test. You get the right system and unmatched support from UEI.

UEI is Perfect for Iron Bird HIL Applications

The Right Simulated Signals for your HIL Application

UEI knows how important it is to virtually test an embedded system. That is why we offer an extensive list of I/O boards to make every day product development and testing safer, faster, easier and more cost effective.



  • Embedded SIMULINK
  • Realtime Linux
  • C/C++ Libraries
  • Many other Languages and OSs supported

UEI offers over 90+ I/O boards to support all your data acquisition, test and control application needs.

Why use UEI for HIL?

  • Ability to simulate and read wide range of values for variables. This enables customers to find failure points with a great degree of accuracy.
  • Harsh condition tested - Enables boards to go wherever they are needed:
    • 5g Vibration
    • 100g Shock
    • -40 to 85º C
  • High level of channel isolation to ensure accuracy up to 350 VRMS.
  • Extremely versatile can be used with a wide range of operating systems and programming languages.
  • Decrease costs by not needing to use a real plant with the embedded system.
  • Scalable due to wide range of chassis available allowing for an increase in boards that all can work together.
  • Meet tight deadlines due to the ability to develop products in parallel
  • Ability to inject failures into the system to see how it would react

Where UEI Is Being Used - Sample HIL Applications

Automotive HIL Applications

UEI HIL solutions are ideal for the development of automotive monitoring test and control applications such as engine, braking, suspension, wheels, hydraulic simulations, and more. UEI rugged hardware enhances vehicle-in-the-loop simulators that are critical to ensuring safety, as we can help simulate a physical car in virtual obstacles and crash scenarios.

Aerospace & Avionics HIL Applications

UEI aerospace and avionics hardware-in-the-loop (HIL) solutions help to reduce system risks by creating virtual environments to test and verify integrated aerospace components and software. Our solutions can be used to ensure successful aerospace performance before actual deployment occurs. UEI HIL hardware and I/O can be used to simulate complete missions, avionic systems, fueling, orbital applications, ground control, flight-line, armament tests, and more.

Application Story: UEI & Blue Origin
Blue Origin needed to consolidate custom and COTS (Commercial Off The Shelf) DAQ and control hardware into one platform to accelerate development, minimize maintenance, and deliver programs on time. UEI's standardized hardware solutions helped Blue Origin save time, accelerate development, and compete in the Space Race.

Dealing with Obsolescence? UEI can help!
VME based systems had been the standard for real-time DAQ and embedded control systems for years. However, due to the age of most VME technology, as well as the lack of vendors in the market, many VME users are now facing “end-of-life” issues. UEI has long-term solutions to replace your VME systems.

UEI & Simulink Solutions

UEI offers Simulink users a powerful and flexible I/O target we call the “UEISIM”. Models built in Simulink are deployed directly on the UEISIM systems using Real-Time Workshop. The combination enables a powerful new solution in the creation and tuning of many real-time and non-real-time applications. These include simulation model verification, rapid prototyping, and hardware-in-the-loop testing.

Designing to Scale: Validation and Verification from Concept to Deployment - Webinar:

Depending on where you are in the verification “V model”, the tasks can be either all virtual, a mix between virtual and real, or all real. Ensuring that your system can scale up and down is critical for safety certification and time to market. We present methods of code and hardware re-use to accelerate the development and deployment of your autonomous, flight or missions controllers.
