Hello ;

Please to type first **Ctrl+j **and to select the simulation you want to run and after setting the simulation directives you type Ctrl+r to run your simulation.

@dhungana.anish01,

Please state you question clearly.

Your simulation will not work for three reasons.

1. You have not read Simulation Tutorial, section (3) marked as essential in (2) in the Forum topic marked [Must read]: https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a;
2. Because you have not read this Simulation Tutorial, you have not understood that you must place a voltage probe (or a .probe statement) into your simulation (see the chapter on Probing Voltages);
3. You have also not understood how to set up the current source at the input to your amplifier by appending AC 1 0 to the end of the current source definition so that you can run an AC Analysis (see the chapter on Configuring Voltage and Current Sources);

Please read the Simulation Tutorial to learn how to run simulations in EasyEDA and therefore why what I have described will fix these problems.

Then your simulation will run.

BTW: the text "V_O" you have placed at the opamp output is just text: it does not function as a netname or as any form of probe.

Thank you very much.
