0 volts in waveform window instead of square wave

Hello, I am completely new to EasyEDA and trying to simulate a simple circuit at https://easyeda.com/editor#id=3b289390b45945b5bfc793a96c2d5b14 After I simulate it shows 0 volts in the waveform window instead of a square wave. I don't know what is the problem. Any help is much appreciated. Thanks in advance :)

The schematic symbol that you have chosen (UA741CP) has no simulation model associated with it. To get up to speed with simulation in EasyEDA, please see (3): https://easyeda.com/andyfierman/Welcome_to_EasyEDA-31e1288f882e49e582699b8eb7fe9b1f and: https://easyeda.com/andyfierman/From_Idea_to_PCB_an_EasyEDA_Design_Procedure-78173f41ed2d468cb6880e6d21483f11

@andyfierman Thanks for your reply. I checked your link and then replaced the op amp with another from **System Components > Spice Simulation** But I am still not getting the desired output. I am getting a constant 1.675 mV. Could you please help me out. https://easyeda.com/editor#id=3b289390b45945b5bfc793a96c2d5b14 Also, is there any way to determine if a schematic symbol has an associated simulation model directly from that symbol in the editor window.

` I am still not getting the desired output.` https://docs.google.com/document/u/1/d/1OWZVVFRAe_2NW3WratpkA_SGuHa5AcRow5ZRfvcoVTU/pub#h.zc05flckh5w0 `is there any way to determine if a schematic symbol has an associated simulation model directly from that symbol in the editor window.` Not directly. You can inspect the Spice netlist to verify that a .model or .subckt has been called up: ![enter image description here][1] [1]: /editor/20180102/5a4b62bd579bd.png
