Abstract
The cost of Burn-In is a major concern for the testing of Automotive Systems-on-Chip (SoC). This paper highlights problematic aspects of a Burn-In flow and describes a two-layered adaptive technique that permits to optimize the stress application and strongly reduce BI test time. At the SoC level, the described methodology adaptively copes with FLASH erase time uncertainties; at the Automatic Test Equipment (ATE) level, the strategy relies on power monitors and tester intelligence. The paper reports experimental results on a SoC manufactured by STMicroelectronics; figures show an optimized usage of stress resources and demonstrates a reduction of 25% of the BI test time when using the proposed adaptive techniques.Pubblicazioni consigliate
