摘要

大型商业数据中心最近强调了一个新的重大测试和可靠性挑战:制造测试转义会在操作期间导致静默数据错误。虽然导致这些故障的潜在原因有很多,但研究指出,随机过程变化造成的时序误差是一个重要因素,在节能低电压操作中尤为突出。筛选这种故障将需要新的和更好的定时测试,可以可靠地检测出具有路径延迟故障的异常电路。

Silent Error Corruption: The New Reliability and Test Challenge
Large commercial datacenters have recently highlighted a new and significant test and reliability challenge: manufacturing test escapes that cause silent data errors during operation. While there are many potential sources that can cause these failures, research is pointing to timing errors from random process variations, accentuated in power saving low voltage operation, being a significant contributor. Screening out such failures will require new and better timing tests that can reliably detect outlier circuits with path delay failures.
