Problems solved by technology

[0003] MRR (Micro-Ring Resonators), the core device of the on-chip optical network, is very sensitive to temperature fluctuations. Temperature changes will cause the inherent resonance wavelength of the MRR to drift, resulting in bridging failures in the MRR.
In addition, the complex

Abstract

The invention discloses an optical router bridging fault positioning method based on a single fault model, and the method comprises the following steps: initializing the specific attributes of each input port and each output port of an optical router, classifying micro-ring resonators in the optical router, and dividing the micro-ring resonators into inlet resonators and outlet resonators; grouping the inlet resonators according to the connected input ports, and inputting test signals corresponding to the inlet resonators at the input ports according to the inlet resonators; after a to-be-tested signal is input, acquiring a first signal detected by each output port of the optical router, comparing the first signal with a standard output signal of each output port of the optical router in a fault-free state, and if the first signal does not conform to the standard output signal of each output port, determining the micro-ring resonator with the bridging fault according to the difference of the output signals.

Description

technical field [0001] The invention relates to the technical field of optical router bridging fault detection, in particular to a method for locating optical router bridging faults based on a single fault model. Background technique [0002] With the development of integrated circuits, blindly improving the performance of single-core processors can no longer increase the computing speed of the system, and even bring additional losses to the circuit. Therefore, it is inevitable for processors to develop from single-core chips to multi-core chips. Multi-core processors can improve the computing performance of chips without changing the original basic design. Network on chip is a chip design scheme proposed under the background of multi-core chip development. However, due to the increasing number of processor cores, the network-on-chip based on electrical interconnection further reduces the distance between cores due to its limited space, which will bring energy consumption a...
