Distributed and Scalable Computation

RT-LAB is capable of executing very large Simulink® models, in parallel, with any I/O capability. Its main uniqueness is its ability to easily share the load over multiple CPUs, even between several simulators with real-time communication links. Additional FPGA-based expansion boxes are also used to extend the connectivity with field equipment. With RT-LAB, users get a cost-efficient, scalable and flexible real-time platform, using only standard off-the-shelf technology.

Optimized for Real-Time

The Linux-based real-time operating system incorporates OPAL-RT’s XHP technology for extreme high performance. Without compromising optimal parallel execution, the simulator’s computational cores are shielded from real-time glitches, for jitter in the microsecond range. RT-LAB comes with an ultra-light backend that guarantees hard real-time constraints, high synchronization accuracy, minimal overhead, and maximal data throughput.

User Interface

Dynamic LabVIEW® Panels

Directly in the RT-LAB user interface, it is possible to open LabVIEW® panels with controls, indicators and waveform graphs. Signals from the Simulink® model can be dynamically assigned to these graphical elements with an easy drag-and-drop operation, even while the simulation is running. Create realistic and sophisticated control panels made of gauges, dials, scopes and virtual instruments.

Easy-to-Tune Simulation Parameters

RT-LAB automatically manages a user console built in Simulink®. It opens at the start of the simulation to display the desired signals and to control parameters. RT-LAB also has a variable table in order to easily view and modify any signals and parameters at any moment. Model testing has never been easier.



RT-LAB’s acquisition system acts like a virtual oscilloscope, by allowing the user to visualize waveforms in real-time without glitches and data loss. It can run continuously or based on user-configured triggers to capture specific events. Its core engine provides the accuracy and the bandwidth for the most demanding real-time applications with hundreds of channels and microsecond precision.


With the possibility of recording thousands of measurement points, RT-LAB provides users with a complete data history. The format is compatible with other post-processing software like Matlab and Scopeview. These advanced acquisition features are done without disturbing the real-time simulation and by keeping a maximal availability for executing the user’s model.

Test Automation


RT-LAB delivers quality analysis and validated results. It runs continuously, maximizing an engineering team’s productivity. RT-LAB’s test environment allows users to create complex execution sequences, simulating various maneuvers and transient conditions. It runs edge case test scenarios that are considered too difficult, dangerous, or simply impossible to perform with physical test benches. With minimal programming skills, users can conduct complex analysis and generate reports. Save time and money, while increasing your test coverage.


RT-LAB offers a complete set of test automation modules designed to write reproducible tests. These modules are based on leading technologies, such as Python, TestStand®, LabVIEW®, MATLAB®, C/C++, and Java. They are easy to integrate with your existing applications.
