Double Module Fault Self-tolerance Design of Telecommand FPGA Chip

The fault tolerant technology on FPGA chip of the telecommand receiving and processing circuit on-boord spacecraft has been researched for the deep space explorer project in this article.By researching the data model of the telecommand receiving and processing circuit in spacecraft,a new double module fault self-tolerance method in small module on FPGA chip of the telecommand receiving and processing circuit in spacecraft has been provided.The telecommand channel FPGA has been optimized in circuit design with this new method,and has been optimized in circuit layout considering FPGA defect cluster.As a result a new generation of telecommand channel FPGA with more strong fault tolerant ability has been developed,which can implement fault tolerance itself and weaken the influence from defect cluster.The new FPGA confirms the correctness and practicability of the new method and can be used in micro satellite and the deep space explorer project in future.
