1、Create a schematic and draw a schematic circuit . Such as a sine wave circuit as follow . ![enter image description here][1] 2、Put the Voltage Probe in the Test point . 3、Simulate the electronic circuits . Click the “ simulate” ICON ,and run the document . ![enter image description here][2] 4、Set the Transient time ,the Maximum Timestep , Stoptime and Starttime . For example the Timestep is 10us, the Stoptime is 10ms , Starttime is 1ms . Then run the document . ![enter image description here][3] 5、Then the simulator Diagram will come out as a wave form file . ![enter image description here][4] [1]: /editor/20151020/562606a1ed4d6.png [2]: /editor/20151020/562606c3a5af8.png [3]: /editor/20151020/562606df4a96f.png [4]: /editor/20151020/562606f131480.png
