The test point also served quality and safety purposes. During production, automated test equipment engaged KMGD to verify power rails and sensor thresholds before parts were approved. A failing unit would be quarantined, its KMGD trace used to log the fault waveform and guide failure analysis. Because KMGD captured nodal behavior without invasive modification, it preserved the unit’s state for subsequent teardown — invaluable when intermittent issues surfaced only under specific loads.
