UVM1.1应用指南及源代码分析 第一章的例子代码

http://bbs.eetop.cn/thread-429900-1-1.html根据这上面的解决方式run_test()改成了run_test("my_case0")可以跑成功，但是把dut端口上的信号拉出来看了一下，怎么全是"X"状态？请教各位大侠！   ps:我用的是Cadence的IES软件仿真的。

driver没有收到数据包，sequence出问题了

问题已解决！谢谢大家！

   请问是怎么解决的啊，我现在跑的一个case出现了个奇葩的问题，编译仿真都没有问题，但是就是时间上没有推进，在#0时间就调用了uvm_root.svh:457行的$finish函数，不知何故，仿真时间上没有推进，没有一点波形信号，起初还以为是clk没跑呢，结果发现不是，求高手相助，多谢。

编译仿真都没有问题，但是就是时间上没有推进, 呵呵，那就是仿真有问题了。
你看下是不是没有raise_objection, 最好把代码贴上吧，

复制源代码应该没问题的！

我不是直接复制的，是自己手动敲了一遍，把编译报出来的问题都修掉了，但是还是不行，报出下面的问题：

不知道为什么就直接在uvm_root.svh:457行finish掉了，仿真时间在0ns不能向前推进，请问你是这样的问题吗？后来怎么解决的啊？

xiangeryong333

解决掉了，sequencer中没有start phase，仿真没启动

请问你有见过这样的warning吗？

是提示我的sequencer和sequence有问题吗？还是只是个warning？
