Abstract
For long-life products,the FPGA bitstream stored in NOR Flash may experience bit flips due to floating-gate charge leakage,which leads to FPGA configuration failure.To address this issue,this paper proposes a Flash refresh method based on FPGA multi-boot.The Flash is refreshed during annual product maintenance to restore the floating-gate charge.The multiboot of the Kintex-7 series FPGA was investigated,and the configuration data composition was restructured to enhance the robustness of configuration.The opti-mized configuration data comprises one header file,two identical copies of the bitstream,and three identical sets of auxiliary file.When launching the Flash refresh,FPGA executes a sequence of steps including self-check,data refresh,and read-back verification to ensure the reliability of the process.The test results have verified that this refresh method is stable and reliable,exhibiting high practical engi-neering utility.关键词
