NI Introduces New Simulator to Help Companies Reduce Test Costs

NI (National Instruments, National Instruments, NI) as a supplier dedicated to providing engineers and scientists with solutions to the world's toughest engineering challenges, announced the launch of a turnkey based on an open modular architecture on August 2 HIL simulators are designed to help embedded software testers in the automotive and aerospace industries maintain software quality while addressing the challenges of increasingly tight time requirements, changing test requirements and shrinking manpower.

Because NI systems are based on open, off-the-shelf hardware and software platforms, new technologies such as camera processing and RF I/O, as well as traditional HIL components, can be easily integrated into a single system. Unlike existing methods, this variability allows engineers to keep pace with advanced technologies such as advanced driver assistance systems, system electrification, and advanced sensor integration (ie, radar). With NI's HIL simulator, test engineers can now choose an open turnkey test system based on an industry-standard platform, rather than a fixed-ended closed test system or the need to completely rebuild the entire system.

“We chose the NI HIL test system because it is based on a standard open platform that allows us to reduce the total cost of testing and the long-term maintenance and total cost of ownership of the hardware,” said Anders Tunströmer of Saab Aviation. “This also makes We were able to customize the system for our needs and speed up the search and repair of embedded software defects in the LRU integration test of the Eagles."

With the HIL simulator, users can customize the system to incorporate camera data, radar target RF measurement and generation, passive entry and passive start, tire pressure monitoring systems and FPGAs to run advanced models to ensure maximum software Test coverage; turnkey HIL simulators are developed using VeriStand test software for real-time simulation, stimulus generation and data acquisition, helping users get started quickly, discovering more defects in a timely manner; multiplexing existing models and hardware Easily integrate third-party software models and third-party systems using the ASAM XIL industry standard.

"Due to changing needs and increasing test coverage, most HIL test systems require a degree of customization in addition to the usual components," said Chad Chesney, vice president of data collection and embedded systems at NI. The common components of these test systems have been standardized, enabling our customers and partners to focus on the areas they are good at, ensuring the development of the most reliable and innovative control systems."

The HIL simulator is the latest system developed based on PXI and CompactRIO open platforms. It uses VeriStand real-time test configuration and data logging software, LabVIEW system design software and NI's newly developed SLSC hardware for standardized signal routing, switching, load and Signal conditioning. The NI HIL system also features a real-time operating system and FPGA technology that is highly customizable while leveraging commercial off-the-shelf components to reduce long-term maintenance risks.
