说明：  ? 参考mcdt_basic_virtual_sequence与mcdt_basic_test之间 的对应关系，将剩余的mcdt_burst_test和 mcdt_fifo_full_test也剥离为virtual sequence与对应的test。 ? 将之前为了满足覆盖率而实现的其它test也按照以上的要求进行 剥离。 ? 在完成以上的virtual sequence与test关系剥离之后，更新后的 测试用例可以通过，且合并后的覆盖率可以满足之前的要求
(Reference between mcdt_basic_virtual_sequence and mcdt_basic_test The remaining mcdt_burst_test and Mcdt_fifo_full_test is also stripped into virtual sequence and corresponding test. * Other tests previously implemented to meet coverage requirements will also be carried out in accordance with the above requirements Be stripped. Updated after the separation of virtual sequence from test Test cases can be passed, and the combined coverage can meet the previous requirements.)
