SpaceFibre is a very high-performance, high-reliability and high-availability network for spaceflight applications. The latest advances in SpaceFibre IP cores for use in radiation-tolerant FPGAs are described. In addition, the results of the radiation campaign implementing SpaceFibre in the Microchip RTG4 FPGA are also presented. The goal of the campaign was to assess the impact of radiation in the performance of the in-built SerDes blocks and SpaceFibre. As expected, the SerDes blocks are sensitive to radiation. However, results also show that the use of SpaceFibre vastly mitigates the effects of radiation allowing to create reliable links even in these extreme conditions.

SpaceFibre is a very high performance, high reliability and high availability network for spaceflight applications. The latest advances in SpaceFibre technology for spaceflight applications are described, including IP cores for use in radiation tolerant FPGAs and SpaceFibre test equipment that can be used to accelerate the development of next generation payload processing systems.
