航天应用FPGA配置可靠性研究
Research on the Reliability of FPGA Configuration in Space-based Systems
摘要
Abstract
Designers of space-based systems face unique challenges to insure each unit against failure.FPGA are used gradually in the aerospace field since it is invented with abundant I/O pins and flexible design margin.Many manufactures have been improving those space-qualified FPGA devices to adapt the aerospace high-radiation environments.FPGA devices based on SRAMs have to load configuration data from external PROMs on power-up before the logic is activated.However, not each batch or each device can be configured successfully with zero-failure.This paper explores every possible factor such as enviroment temperature, signal integrality, configuration rate and so on.Aiming at Xilinx FPGA devices, this paper provides a series of safeguard solutions for higher reliability of configuration.It has significant reference value in aerospace application fields for its feasibility and reliability.关键词
