摘要： 负偏置温度不稳定性为主的老化会造成时序违规故障及软错误故障。为此，提出软错误与老化在线检测器(SEAOS)。在器件正常工作的情况下，在线检测上述2种故障。复用并发内建逻辑块观察器，使得硬件开销不超过30%。实验结果表明，在0.18 μm工艺尺寸下，与经典检测结构相比，SEAOS有较好的检测能力，且硬件开销较少。

Abstract: Aiming at the dominant aging mechanism induced by Negative Bias Temperature Instability(NBTI) and the soft error, e.g. Single Event Upset(SEU), affect the normal operation of the device, this paper presents a sensor called Soft Error and Aging Online Sensor(SEAOS) that can on-line detect soft error and aging when the device is under its normal operation, to against SEU and the timing violations induced by aging. Due to the reuse of Concurrent Built-in Logic Block Observer(CBILBO), the hardware overhead below 33.46% is well tolerated. Experimental results demonstrate that, compared with several classical structures by employing 0.18 μm technology process, SEAOS has a good capacity of detection and a lower hardware overhead.

Key words: Soft Error and Aging Online Sensor(SEAOS), aging, Single Event Upset(SEU) fault, reuse, Negative Bias Temperature Instability (NBTI), Concurrent Built-in Logic Block Observer(CBILBO)
