Note: I just noticed the red dots at the gnd on the source side of the MOSFET, deleted it and drew a new conductor but no change in the results.

...And the MOSFET pins are in fact manually edited, but only on the PCB-column. This had no effect on the simulation outcome, just a desperate attempt to getting it to work. Sorry for the confusion.

Hi Fopplan, Welcome to EasyEDA. The default model used for the NMOS_E symbol is for a basic low current device. To pass more current, you need to set up a model for a higher power device. To find out how to do this, please have a read through of the EasyEDA Simulation eBook and a play with the examples in there: https://docs.google.com/document/u/1/d/1OWZVVFRAe_2NW3WratpkA_SGuHa5AcRow5ZRfvcoVTU/pub in particular: **Device models** https://docs.google.com/document/u/1/d/1OWZVVFRAe_2NW3WratpkA_SGuHa5AcRow5ZRfvcoVTU/pub#h.43ky6rz** and: **Schematic symbols: prefixes and pin numbers** https://docs.google.com/document/u/1/d/1OWZVVFRAe_2NW3WratpkA_SGuHa5AcRow5ZRfvcoVTU/pub#h.pkwqa1 (The Google links above are 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.)

Nice! Thank you. Ive also found that many manufacturers provide spice models for specific components, which you can import into the schematic (found a past forum post of yours, Andyfierman). Im just going to leave the link below if anyone is interested. [How to import spice models for simulation][1] [1]: https://easyeda.com/forum/topic/Include_spice_model_from_internet-NnhVdvpHY

Hi Fopplan, The EasyEDA Simulation eBook covers everything that's in the post you have given a link to but in more detail and with simulation examples to try out. Remember to use the link to the Google Docs version until we fix the EasyEDA copy. Beware that not all devices have spice models and not all models will run in ngspice. Some need editing to some degree to make them work but some just cannot be run in ngspice at all. For example, LTspice VDMOS models do not work at all whereas some models need a lot of editing to get them into a syntax that ngspice understands. If you have problems finding or running a model just contact us and we will try to help.
