| 摘 要： | 通过研究源隔离策略为典型代表的版图加固措施，评价多种考虑源隔离策略加固结构的单粒子瞬态响应，验证并报道了产生的相反效果。除寄生双极放大效应，驱动能力和节点电容均能对单粒子瞬态产生影响，由于受多个因素调控，除非某因素确定无疑是最主要的影响因素，在采取加固措施之前必须经过仔细考虑以及定量评估。

| Abstract: | Single event transient (SET) response was compared between various structures considering source isolation mitigation technique. The simulation results prove the existence of adverse effects. Besides bipolar amplification effects, both drive strength and node capacitance should be considered when trying to improve SET tolerance. Due to the nonuniqueness of related factors, unless one factor is definitely the main contributor, careful consideration and quantitative evaluation are highly suggested before implementing mitigation techniques. |
