System-Level Test In The AI Era: Validating Reliability At Scale

As AI moves from a specialized workload into mainstream infrastructure, backend test is undergoing a quiet but decisive shift. The questions customers ask of test are changing, and so is the role test plays in the broader manufacturing flow. For decades, the industry operated with a simple guiding question: do we have a “Known Good Die (KGD)” defined? From wafer sort through final test, automated test equipment (ATE) has answered that question effectively, serving as the backbone of silicon vali
