Hi, You need to add power for your schematic. check my public project <https://easyeda.com/project_view_Simulating-OSCIllators_jb5YSasmE.htm> Please let me know U next try.

If you change the Value expression used in V2 from: `15` to: `PULSE(14 15 0 1u)` this will generate a VCC rail that is +14V for time T<0 and steps up to +15V at T=0. This 'kicks' the circuit into oscillation much earlier (<20ms) that if left to start up just relying on internal imbalances and numerical 'noise'. There's an example of this in: <https://easyeda.com/project_view_Projects-for-beginners_tqkewO60i.htm> in: <https://easyeda.com/project_view_Projects-for-beginners_tqkewO60i.htm> and a way to quick start up a cystal oscillator which illustrates a technique than can be applied to other circuits: <https://easyeda.com/file_view_Crystal-oscillator-using-EasyEDA-quick-starting-crystal-model_a71jBTb5n.htm> in: <https://easyeda.com/project_view_How-to-use-basic-elements-of-EasyEDA_BDxrlDVdv.htm> :)

Hi, Today (4 years after this post was published) I tried to run the Oscillator model from the above link (Crystal oscillator using EasyEDA quick starting crystal spice model) and again I got the same issue I have with my model with the same crystal, because of which I started looking for the answer on blogs. Can anyone please help and explain how to simulate oscillators with crystals?

Your project is private so only you can see it. Therefore we cannot diagnose what may be wrong in your simulation. You probably have chosen one or more schematic symbols that have no spice model associated with them.
