I did..but in my project there is no component with XNO name and there are also no other projects and copies open.

Are you sure you have no copies of the schematic in the *same* project (it does not matter if they are open or not)? Can you make a copy of your project public? If not, can you share it privately with me? https://easyeda.com/Doc/Tutorial/share.htm#Access-Control My email is my username as in this post followed by the usual `@easyeda.com`

@andyfierman I have shared it with you...tell me mistakes if any (I am beginner in easyeda)

Hi Ashwinimeena8, It will take a while to work through your simulation schematic. There are several things wrong with your circuit but rather than go through them here on the forum it would be easier to continue thie discussion by email. If you would like to contact me directly I will reply to your email. Also, please (i) make the shared project so that I have read and write access and (ii) make a backup copy of your schematic in the same project so that I can edit one copy and you can see the changes. In the meanwhile please read this: https://docs.google.com/document/u/1/d/1OWZVVFRAe_2NW3WratpkA_SGuHa5AcRow5ZRfvcoVTU/pub and run the linked simulations. That will help you to build simulations and understand some of the things that I will try to explain. :) (The Google link above is to the original copy of the Simulation eBook which you can also find at: https://easyeda.com/Doc/Simulation-eBook/ but the table of contents in the EasyEDA copy is broken and misses out some sections. We are working to fix it but in the meanwhile the copy published to the web from Google Drive works just as well.)

I have made the project shared, now you can modify it

If you are happy to do that in this public forum, then I can do that. Otherwise, you still need to email me so I can explain the issues. :)
