Summary: | The invention discloses a fault detection device and a fault detection method for an MRR (Micro Ring Resonator) fault in a PNoC (Photonic Network-on-Chip). In view of a fault caused by manufacturing defects and the sensitiveness of an MRR to great temperature fluctuation, a fault model is built, and a PNOC architecture composed of a laser array, a test vector generator, a control vector generator, a data coupler, an MRR under test and a square box is designed. The data coupler couples test data into an optical path. The on-off state of the MRR is controlled. Fault analysis and diagnosis are carried out based on collected test response.
本发明公开种PNoC中MRR故障检测装置及方法,针对由于制造缺陷以及MRR对温度高度波动敏感而造成的故障,首先建立故障模型,并且设计种由包括激光器阵列、测试矢量发生器、控制矢量发生器、数据耦合器、待测的MRR和方形盒所构成的PNOC架构,通过数据耦合器将测试数据耦合到光路当中,通过控制MRR的开和关状态,对采集到的测试响应分析,进行故障分析和诊断。 |
