With　the　development　of　large　scale　integrated　circuits,　the　functions　of　the　IoT　chips　have　been　increasingly　perfect.　The　verification　work　has　become　one　of　the　most　important　aspects.　On　the　one　hand,　an　efficient　verification　platform　can　ensure　the　correctness　of　the　design.　On　the　other　hand,　it　can　shorten　the　chip　design　cycle　and　reduce　the　design　cost.　In　this　paper,　based　on　a　transmission　protocol　of　the　IoT　node,　we　propose　a　verification　method　which　combines　simulation　verification　and　FPGA-based　prototype　verification.　We　also　constructed　a　system　verification　platform　for　the　IoT　smart　node　chip　combining　two　kinds　of　verification　above.　We　have　simulated　and　verificatied　the　related　functions　of　the　node　chip　using　this　platform　successfully.　It　has　a　great　reference　value.　©　2018　IEEE.
