What Is NI VeriStand? And When You Need It

VeriStand is National Instruments' software for configuring real-time test applications, most notably hardware-in-the-loop (HIL) systems. Where LabVIEW writes code, NI VeriStand lets you configure a real-time test system, channels, models, stimulus, and logging, without building it all from scratch.

What VeriStand does

VeriStand software provides a framework for real-time testing:

• •Run real-time models (for example, Simulink models) on NI real-time hardware.
• •Map I/O to channels and configure the test system through a UI.
• •Define stimulus profiles and alarms for automated runs.
• •Log and monitor data during execution.

It is most often used to stand up hardware-in-the-loop rigs for automotive, aerospace, and energy controllers.

How VeriStand relates to the rest of the NI stack

VeriStand usually runs on NI real-time and FPGA hardware (the same world as LabVIEW Real-Time and FPGA) and is frequently paired with a test sequencer for automation. That is three separate paid products working together, which is part of why NI HIL setups are expensive.

What it costs and its limits

VeriStand is a paid NI product and requires NI real-time hardware. It is powerful for HIL, but the cost and lock-in are significant, and the value is concentrated in the real-time execution layer, not the broader job of planning and analyzing tests.

Where TestFlow fits

Real-time execution will always need specialized hardware, and that is not what TestFlow replaces. What TestFlow does replace is the slow, manual work around it: defining validation plans, generating test scripts, and analyzing results, vendor-agnostic and AI-assisted. For the planning and automation layer that surrounds a VeriStand rig, the free version is a fast way to see the difference.

Frequently asked questions

What is NI VeriStand used for? Configuring and running real-time test applications, especially hardware-in-the-loop systems, on NI real-time hardware.

Is VeriStand the same as LabVIEW? No. VeriStand is a configuration-based real-time test environment. LabVIEW is a general programming language. They can be used together.

Do I need VeriStand for HIL? It is one common option for NI-based HIL, but not the only one. The test automation and planning layer can be handled separately and vendor-agnostically.
