NI VeriStand 2025 Q3

NI VeriStand 2025 Q3

NI VeriStand is a powerful, ready-to-run software framework for configuring real-time testing applications, including Hardware-in-the-Loop (HIL) simulation, test cell control, and recorded data playback. It provides an out-of-the-box environment to deploy and execute real-time models (from Simulink, LabVIEW, FMUs, etc.), manage I/O with NI and third-party hardware, create custom stimulus profiles, and build interactive operator interfaces for monitoring and control—all without low-level programming. Its core strength is dramatically reducing the time from concept to a running, scalable real-time test system.

It is the central execution engine in NI’s platform for validating complex systems like engine ECUs, flight controllers, power converters, and industrial machinery.

Key Features & Capabilities

VeriStand is a configuration-based framework, not a programming environment, designed for rapid test system deployment.

Core Real-Time Execution Engine:

1. Real-Time Model Deployment:

   • Multi-Environment Model Import: Directly import and execute models from Simulink, LabVIEW, FMUs (Functional Mock-up Units), and compiled C/C++ code on a real-time target (PXI, CompactRIO, Industrial Controller).

   • Scheduler Configuration: Define deterministic execution rates for multiple models and tasks.

2. Hardware I/O & Channel Management:

   • Extensive I/O Support: Pre-configured support for thousands of NI DAQ, C Series, and R Series modules, as well as third-party CAN, LIN, ARINC 429, MIL-STD-1553, and AFDX interfaces.

   • Channel Mapping Wizard: Graphically map model variables (e.g., throttle position, RPM) to physical I/O channels (e.g., analog voltage, CAN signal).

3. Stimulus Profile & Scenario Creation:

   • Workspace Editor: Create and edit complex time-based stimulus profiles (step, ramp, sine, custom waveforms) and scenario sequences to automate test execution.

   • Alarms & Limits: Define software alarms and limit checking on any system channel.

4. Customization & Interfacing:

   • Custom Device Interface: Framework to integrate custom I/O hardware or communication protocols into the VeriStand engine.

   • .NET & Python API: Full APIs for extending functionality, automating configuration, and integrating with enterprise test executives.

Operator Interface & Data Management:

1. Interactive Workspace Screens:

   • Runtime Editing: Create operator screens with gauges, graphs, buttons, and indicators for real-time monitoring and control. Screens are runtime-editable without stopping the test.

   • Workspace Synchronization: Multiple clients can connect to the same real-time engine, seeing synchronized data.

2. Data Logging & Analysis:

   • High-Speed Logging: Stream data from the real-time engine to disk in binary (.tdms) or other formats with precise triggering.

   • Integration with DIAdem & InsightCM: For automated post-test reporting, dashboarding, and asset monitoring.

What’s New in the 2025 Q3 Release:

• Enhanced Model Support: Updated integration for the latest versions of Simulink and support for newer FMI/FMU standards.

• Expanded Hardware Support: Drivers and configuration for NI’s latest PXI and C Series modules.

• Performance & Usability Improvements: Optimizations to the real-time engine and Workspace UI.

• Security Enhancements: Updated security protocols for networked systems.

• Bug Fixes & Stability: Resolves issues identified in previous quarterly releases.

🖥️ System Requirements

VeriStand uses a distributed architecture: a Host PC for configuration/UI and a Real-Time Target for execution.

Host PC (Development/Operator Station) Minimum Requirements:
Windows 10/11 (64-bit), multi-core processor (Intel i5 or equivalent), 8 GB RAM, 20 GB free disk space, and a 1920×1080 display.

Real-Time Target (Execution Hardware, e.g., NI PXI Controller) Requirements:
Determined by the specific NI hardware (e.g., PXIe-8880 controller). Runs a real-time OS (NI Linux Real-Time or Phar Lap ETS).

Recommended Professional Setup:
A powerful Host PC with an Intel i7/i9 or Xeon CPU, 32 GB RAM, an SSD, and multiple monitors. Real-time targets are selected based on model complexity and I/O count, often requiring multi-core real-time processors and high-bandwidth chassis.
