The　digital　temperature　sensor　based　on　the　logic　resources　of　the　FPGA　can　monitor　the　global　temperature　of　the　Field　Programmable　Array　(FPGA)　in　real　time.　This　paper　implements　this　temperature　sensing　network　on　a　Xilinx　XC7Z020　FPGA　in　28　nm　process,　which　uses　a　logic　consumption　of　384,　occupying　only　0.7%　of　the　total　Look-Up-Tables　(LUTs).　A　single　sampling　time　is　60　μs,　which　ensures　data　reliability　and　stability.　The　total　on-chip　power　consumption　of　the　system　is　approximately　5　W,　and　the　realization　of　the　distributed　temperature　measurement　network　is　realized　under　the　condition　of　small　power　consumption　and　resource　occupation.　©　2023　IEEE.
