Vivado

[Synth 8-6895] The reference checkpoint 
.srcs/utils_1/imports/synth_1/system_wrapper.dcp is not suitable for use with incremental synthesis for this design. Please regenerate the checkpoint for this design with -incremental_synth switch in the same Vivado session that synth_design has been run. Synthesis will continue with the default flow

Tools→Settings→Synthesis→Incremental synthesis→Disable（轻易不要使用）
