AI中文摘要：
基于SRAM的FPGA系统级芯片器件在配置存储器中容易受到单粒子翻转（SEU）的影响，这可能扰动可编程路由资源并降低通信结构的性能。在现代Zynq UltraScale+ MPSoC中，此类路由扰动可引入小的传播延迟偏移，这些偏移在逻辑上保持透明，但会损害基于AXI的数据传输并导致静默数据损坏。尽管路由延迟退化和AXI互连故障已被独立研究，但它们在中子辐照下的实验相关性尚未建立。本工作对ZCU104平台进行了跨层研究，将路由主导的延迟传感器与包含复制加速器的AXI互连基准相结合。在完全运行的系统上进行了中子辐照实验，同时通过内部配置访问端口实现的帧级配置故障注入器支持受控的翻转模拟。测量的路由延迟事件与通信故障进行统计关联，并推导出时序偏移和AXI故障两者的截面。实验结果证明了中子引起的路由扰动如何在UltraScale+ MPSoC中传播为系统级静默数据损坏，为富中子环境中面向弹性的基于AXI的设计提供了见解。
英文摘要：
SRAM-based FPGA system-on-chip devices are vulnerable to single-event upsets (SEUs) in configuration memory, which may perturb programmable routing resources and degrade communication fabrics. In modern Zynq UltraScale+ MPSoCs, such routing disturbances can introduce small propagation delay shifts that remain logically transparent yet compromise AXI-based data transfers and lead to silent data corruption. Although routing delay degradation and AXI interconnect failures have been studied independently, their experimental correlation under neutron irradiation has not been established. This work presents a cross-layer investigation on a ZCU104 platform integrating routing-dominated delay sensors with an AXI interconnect benchmark comprising replicated accelerators. Neutron irradiation experiments were conducted on the fully operational system, while a frame-level configuration fault injector implemented via the internal configuration access port enables controlled upset emulation. Measured routing delay events are statistically correlated with communication failures, and cross-sections for both timing shifts and AXI malfunctions are derived. The results experimentally demonstrate how neutron-induced routing perturbations propagate into system-level silent data corruption in UltraScale+ MPSoCs, providing insight for resilience-oriented AXI-based design in neutron-rich environments.
