Download NI VeriStand 2025 Q3 – Real-Time Test System Software for Hardware-in-the-Loop Simulation

NI VeriStand 2025 Q3 is a robust real-time testing software framework developed by National Instruments (NI). It is engineered to configure and deploy advanced Hardware-in-the-Loop (HIL) simulations, manage test cell operations, and execute recorded data playback. This software is critical for professionals in industries such as automotive, aerospace, and industrial machinery, enabling efficient validation of complex embedded systems like engine ECUs, flight controllers, and industrial automation equipment.

Overview of NI VeriStand and Its Role in Real-Time System Testing

NI VeriStand functions as a configuration-based framework designed for rapid deployment of real-time test systems. Unlike traditional programming environments, it allows engineers to quickly assemble and deploy test applications. Its primary role involves creating and managing Hardware-in-the-Loop simulations, which are vital for testing embedded controllers in an environment that closely mimics real-world operating conditions. The software targets key industries, including the automotive sector for validating engine ECUs and power converters, aerospace for testing flight controllers, and industrial machinery for embedded system validation and automation.

Model Deployment and Real-Time Execution Capabilities

The core of NI VeriStand’s functionality lies in its ability to deploy and execute real-time models. It supports the direct import and execution of models developed in environments such as MathWorks Simulink, National Instruments LabVIEW, Functional Mock-up Units (FMUs), and compiled C/C++ code. These models are deployed onto real-time targets, including NI’s PXI and CompactRIO hardware platforms, as well as other industrial controllers. The software features a configurable scheduler that ensures deterministic execution rates, allowing for precise control and accurate simulation of system dynamics under stringent timing requirements. This capability extends to managing multiple models within a single test system, ensuring complex simulation scenarios are handled efficiently.

Comprehensive Hardware I/O and Channel Management Support

NI VeriStand offers extensive hardware compatibility, integrating seamlessly with a wide range of I/O devices. It natively supports National Instruments’ data acquisition (DAQ) modules and modules for the PXI and CompactRIO systems, providing a versatile platform for data acquisition and control. Beyond NI hardware, the framework extends its reach to support numerous third-party communication buses and protocols. This includes industry-standard interfaces such as Controller Area Network (CAN), Local Interconnect Network (LIN), ARINC 429 for avionics, and MIL-STD-1553. The software includes a channel mapping wizard that simplifies the process of associating system variables within the simulation with physical I/O channels on the connected hardware, streamlining test system configuration.

Advanced Test Automation with Stimulus Profiles and Scenario Controls

Engineers can leverage NI VeriStand’s workspace editor to construct sophisticated test automation sequences. This includes creating time-based stimulus profiles that replicate real-world inputs and environmental conditions. The software also supports the development of complex scenario controls, allowing for the sequencing of tests and the simulation of dynamic events. Furthermore, engineers can configure alarms and limits to monitor critical parameters during real-time execution, automatically flagging deviations or failures. These automation features, combined with trigger-based test execution, enable efficient and comprehensive validation of embedded systems, reducing manual intervention and enhancing test repeatability.

Interactive Operator Interfaces and Data Management Tools

NI VeriStand facilitates interactive operation and data analysis through its customizable operator interface. This interface can be designed with runtime-editable screens, allowing test operators to adjust parameters and parameters or respond to system changes without halting the test sequence. The software supports the synchronization of multiple operator clients, enabling remote monitoring and control of test systems from various workstations. For data management, NI VeriStand supports high-speed data logging in various formats, which can be easily integrated with other NI tools like DIAdem for post-test analysis and InsightCM for enterprise-level condition monitoring and reporting. This integration ensures that test data is efficiently captured, analyzed, and archived for comprehensive reporting and diagnostics.
