如图所示，生成的sv代码中，所有名字里带有set_io_out的function都没有被覆盖到，这可能是什么原因？这些function是什么功能？在截图的这个测试中，PredChecker的功能点都进行了测试。 |

在 xx_top.sv 封装文件中的所有覆盖率信息都可以忽略。这些函数是为了IO引脚赋值的DPI函数，set写/get读。对于out是不支持set写的。 All coverage information in the xx_top.sv wrapper file can be ignored. These functions are DPI functions for assigning values to IO pins, set for writing and get for reading. For output, set writing is not supported. Coverage information only considers the design part. |

覆盖率信息只考虑最核心的部分。
