Real-Time Sequence Example Library

[NAKeel]

Overview

The real-time sequence example library provides a starting point for creating and using real-time sequences using NI VeriStand 2011 and newer.  This functionality is commonly used for any sort of real-time testing that requires test automation or real-time stimulus generation. This example library contains real-time sequences that include:

1. A state machine example that outputs a sine wave, square wave, sawtooth wave, and a triangle wave
2. A swept sine wave generator whose sine output increases linearly as the sequence runs
3. A logarithmic swept sine wave generator whose sine output increases logarithmically as the sequence runs
4. A damped sine wave generator whose amplitude shrinks as the sequence runs
5. A benchmarking sequence that determines primary control loop rate and monitors the system to ensure on-time operation
6. A multi-tasking fault injection sequence that generates a ramp signal in one task and performs triggered fault injection in the other task.

Instructions for Use

All of the attached real-time sequences function on their own and can be incorporated into a stimulus profile.  However, since many test cases are application specific, they are often more useful as a demonstration for the types functions that are available in the stimulus profile editor. 

Installing the Real-Time Sequence Library

To use the Real-Time Sequence Library, unzip the add-on files and place them in any accessible location on your hard drive.

If you would like to have these real-time sequences available in the User Library, place them in <National Instruments\NI VeriStand 2011\Stimulus Profiles\Library\User.

Requirements to Run the Real-Time Sequence Library

These real-time sequences have been created using NI VeriStand 2011, so NI VeriStand 2011 or newer is required to run them.

Software

This device was created for use with NI VeriStand <version>.  To use this custom device you must have the following software installed:

• Bulleted list of required software

Hardware

No hardware is required to use these real-time sequences.  However, they can run on real-time hardware and communicate with any device that is supported by NI VeriStand.

Requirements to Modify the Real-Time Sequence Library

These real-time sequences have been created using NI VeriStand 2011, so NI VeriStand 2011 or newer is required to edit them.
