Hardware-in-the-loop (HIL) testing evaluates a real controller connected to a real-time simulation of the system it controls. Simulated sensor inputs and responses let engineers examine controller behavior under defined conditions before or alongside testing with the complete physical system.
Sift brings HIL telemetry into the same analysis environment used for test stands and operating hardware. Engineers inspect controller signals in Explore, compare Runs, and evaluate recorded behavior against defined checks.
After a firmware change, for example, a team can compare a new HIL test with a baseline under equivalent simulated conditions. The comparison can show where response timing or signal behavior changed. Reusable checks and Reports then support hardware regression testing by keeping detected conditions connected to their review.
