Research and Design of On-Board Spacewire Route

SpaceWire (SpW) is a well know communication standard platform proposed by European Space Agency (ESA). Due to its inherent properties of faulttolerant and high-throughput, it is extensively used in avionics and satellite applications. When more than two SpW nodes communicate, a SpW Router is used. Such routers can be implemented in ASICs or in programmable devices. In order to perform fault tolerance experiments and since was not possible to find an open source of SpW Router, in this paper we present an open VHDL implementation of this router. Simulation was performed in order to validate the system, and synthesis results for ASIC and FPGA are presented. Finally, in order to analyze the SpW router behavioral when soft errors happen, a fault injection campaign was implemented and results were presented.

In this paper, we present a SpaceWire router IP protected against soft errors by using design level fault tolerance techniques. In order to obtain a low overhead and high protection, a fault injection experiment was performance to evaluate the most susceptible functions in the protocol. Based in the results, fault detection techniques were implemented in RTL level just in the most critical elements. Final results show that the error detection capability of the proposed IP increases in more than 100% with minimal area and performance overhead. The IP targets ASIC or Flash-FPGA platforms.
