Hi, I've just started using EasyEDA since yesterday trying to simulate one of my projects using optocoupler. As far as I know, I need to be in simulation mode and the icon in the library need to have an "S" symbol as "simulatable". However, my optocoupler which I get from the library under "user-contributed" received an error message saying "it haven't spice model", despite having the "S" symbol in the library. I've been searching online but to no avail. Can I have further clarification? Thanks.
