说明：  1. 理解mcdf_root_test::gen_stop_callback()和 mcdf_root_test::run_stop_callback()的作用。 2. 按照实验代码中的要求，实现测试用例mcdf_burst_test，并 且在波形中检查三个通道的激励是否按照符合BURST发送要求。 3. 实现测试用例mcdf_fifo_full_test，在满足至少有两个 channel的ready信号同时拉低时，并且channel FIFO中的数 据全部从MCDT送出时，才可以停止测试。 4. 请在仿真中添加额外的仿真选项 -solvefaildebug // 为了给出更多随机化失败的调试信息 -sv_seed NUMBER // 可调整随机种子值为NUMBER -classdebug // 为了显示更多与类/对象调试有关的信息
(1. Understand mcdf_root_test:: gen_stop_callback() and The function of mcdf_root_test:: run_stop_callback(). 2. According to the requirement of the experiment code, the test case mcdf_burst_test is implemented, and In the waveform, the excitation of the three channels is checked to meet the BURST transmission requirements. 3. Implementing the test case mcdf_fifo_full_test, which satisfies at least two requirements Channel's read signal is lowered at the same time, and the number in channel FIFO Only when all the data are sent out from MCDT can the test be stopped. 4. Please add additional simulation options to the simulation - solvefaildebug // / To give more debugging information about randomization failures - sv_seed NUMBER//adjustable random seed value NUMBER - Classdebug // To show more information about class / object debugging)
