错误记录：[Synth 8-6895] The reference checkpoint

报错详情

点击查看代码

[Synth 8-6895] The reference checkpoint E:/Projects/Vivado2023/2.ExampleDesign_my/iic_ms/iic_ms.srcs/utils_1/imports/synth_1/Master.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

# 解决方法

点击“Reset Output Products”,等待完毕之后执行“Generate Output Products”

后续我也删除了.dcp文件，没有继续报错了

解释

增量合成更新失效了，相当于工程改变了。
