quartus 2 仿真问题

请问各位高手,在Quartus中进行波形仿真,在simulator tool中选中check out outputs时,仿真通不过,显示错误Error: Simulation results do not match expected results from vector source file d:/programme/example/study.vwf
Error: Logic level(s) do not match expected level(s)
Error: Logic level 0 does not match expected logic level X for node y at time 0 ps
不选中时可通过,但输出为‘X’。
这是为什么?
