Please have a look at the EasyEDA Simulation eBook at: https://docs.google.com/document/d/1OWZVVFRAe_2NW3WratpkA_SGuHa5AcRow5ZRfvcoVTU/pub (There's a copy at: https://easyeda.com/Doc/Simulation-eBook/ but the table of contents is broken and it misses out a section. We are working to fix it but in the meanwhile the copy published to the web from Google Drive works just as well.) Please post back if you need more help. :)

The Simulation eBook describes ways of associating different spice models to the symbols and how to create your own symbols and attach models to them. A list of spice models available in EasyEDA can be downloaded in pdf format from here: https://docs.google.com/spreadsheets/d/1KM28xzXwgQeUUj3zRMlth9BN-vs6Q98KBk1FHXmf58U/pub?output=pdf
