For ECU and body electronics manufacturers in transportation markets, closed-loop feedback with hardware-in-the-loop (HIL) simulation is essential for providing superior test coverage and correcting anomalies earlier in the design cycle. As an NI HIL Specialty Partner, WTI has the expertise to help you build a customizable, cost-effective HIL test system that easily closes the loop with National Instrument’s open, commercial off-the-shelf (COTS) technology.

Test Development and Management Software
Our software of choice is NI VeriStand, a powerful real-time testing and simulation environment that runs native models without any recompiling or extra licensing fees. We also build with NI LabVIEW, INERTIA, CANalytics, and other software.
Real-Time Processing and Data Acquisition
The PXI hardware platform is ideal for HIL testers because of its high-performance, real-time controllers and more than 1,500 modules to choose from. Plus, expansion I/O is easy to add for complex or high channel count applications.
FGPA Capabilities for Deterministic Timing
Using customizable field-programmable gate array (FPGA) chips in HIL systems can enhance real-time testing and simulation with deterministic, nanosecond timing.
Switch, Load, and Signal Conditioning
WTI has partnered with OrangeWire Systems to offer NI SLSC modules capable of providing signal conditioning, fault insertion unit (FIU) and load testing, reference voltage handling, current measurement, and more.
Connectivity to Device Under Test (DUT)
A mass interconnect that interfaces with the DUT makes life easier with greater flexibility and reliability. The mass interconnect allows the test equipment to quickly and easily connect with the DUT in one clean move.
With the technology boom of the last decade, the race for first to market has never been more apparent. Industries known for fast-paced innovation must often develop large, complex systems with multiple, dependent subsystems, all at the same time. As systems become more complex, testing systems must evolve. Hardware-In-The-Loop (HIL) testing can speed up the R&D process without sacrificing accuracy, while keeping testing costs down.
HARDWAREThe Switch, Load, and Signal Conditioning (SLSC) platform smoothly integrates with the rest of the NI real-time platform and reduces signal routing complexity. These off-the-shelf modules use high-power relays for signal switching, power loads, and additional inline signal conditioning capabilities.
NI VeriStand significantly reduces development and test time. Its out-of-box functionality includes configurable data logging, test sequencing, stimulus generation, and model execution. Most notably, VeriStand has the ability to accept custom code and simulation models from other environments.
