candence设计新手问题

微光倾城

我一开始仿真还可以跑出来，我是个新手，可能过程中点了不该点的还是怎么回事，我也不太清楚，突然就仿真一直报错了
我把报错也粘到这里：

ERROR (WIA-1175): Cannot plot waveform signals because no waveform data is available for plotting.
One of the possible reasons can be that 'Save' check box for these signals are not selected in the Outputs Setup pane. Ensure that these check boxes are selected before you run the simulation.
