Perform LRU HIL and Embedded Software Testing
Aerospace and defense test engineers need a more flexible way to perform embedded control software validation for line-replaceable units (LRUs) with limited time, budget, and resources. LRUs are becoming more complex, and test requirements are continuously changing throughout development. So, teams must create modular test systems that can adapt to design changes and support the full validation workflow from initial model testing to hardware in the loop (HIL) and system integration testing.
Application Requirements
Modified off the shelf (MOTS) systems aligned to application requirements, models, signals, and sensors
Reuse model IP within existing engineering workflows
Standard cables and connectivity in place of point-to-point wiring
Full test coverage including real/simulated signal switching and fault insertion of conditioned signals, avionics buses, and more
LRU Test System
- Integrate models from the tools of your choice, including MathWorks® Simulink® software, with VeriStand on NI Linux Real-Time
- Capture measurements, data, and messages from communications buses with PXI and custom capabilities with PXI FPGA and LabVIEW-programmable FPGA
- Reuse modular signal conditioning, fault insertion, I/O simulation, and standard cabling between test systems with NI Switch Load Signal Conditioning (SLSC) hardware
- Build, deploy, and automate your real-time validation test system with TestStand test management software
- Accelerate design and deployment of LRU HIL test solutions with the System on Demand design methodology
Solution Advantages
-
Flexible system completion, service, and support options through System on Demand.
-
Access to advances in COTS hardware and software for complex LRU test needs.
-
Reduced schedule and coverage risk with a modular, scalable, and adaptable validation approach
-
Expand existing test assets with new test capability as requirements change
“We would not have reached some of our goals, and the ones that we have on the horizon for Midnight, without NI and the NI family.”
