Our Testing Approaches
Integrated testing for smarter engineering
Hardware-in-the-loop
HIL simulation is the gold standard for developing and validating the most advanced control, protection, and monitoring systems.
Power hardware-in-the-loop
PHIL simulation builds on HIL by introducing real power exchanges between simulated and physical systems.
Rapid control prototyping
RCP enables faster control development by integrating models, typically based on MATLAB/Simulink™, directly into a real-time simulator.
Software-in-the-loop
SIL testing allows engineers to integrate compiled production code directly into a real-time simulation environment.
Simulation acceleration
Our simulation acceleration technology uses the full capacity of multi-core architectures to significantly reduce simulation time, especially for computationally intensive tasks like EMT simulations.
Digital twins for advanced simulation
By creating virtual replicas of physical systems, organizations can gain deeper insights, troubleshoot issues before they arise, and explore innovative solutions to complex challenges.
