Integrate physical hardware with simulated environments to exercise real-time control logic. Use this skill whenever the user mentions hardware in the loop, hil, real time testing, control logic, test rig, signal injection, plant model, or is working with dSPACE, Simulink, NI VeriStand, even if they never say "hardware in the loop testing" explicitly. Routes live lookups through the Automated-Real-Time-Test-Runner endpoint. Do not use it for unrelated application feature work or general coding questions.
