Hardware-in-the-Loop Test System

An open, adaptable platform is essential to the long-term success of your hardware-in-the-loop (HIL) test investment. With support for multivendor I/O and the power of National Instruments LabVIEW FPGA, your NI HIL test system can always to adapt to the latest technologies while providing the most cost-effective solution.

In this reference architecture:

• The user interface and test management utilities are configured and monitored on the host.
• The real-time simulator produces real-world electrical interactions between the embedded controller and the test system.
• Using physical loads and a fault insertion unit, the HIL test system can accurately simulate real-world conditions and test response to fault situations.
• You can use third-party hardware and software for all components of the HIL test system in place of the NI products suggested in this architecture.

Configuration 1 uses a simulator based on PXI. PXI is an open, multivendor standard for modular instrumentation that offers:

• 4 to 18 slots for I/O (extendable with additional chassis)
• A variety of off-the-shelf, real-time controllers that use the latest advances in PC technologies
• Pico-second timing and synchronization capabilities

Configuration 2 uses a PC-based simulator to provide a lower-cost option for applications with smaller channel counts.
