Hi Rui, Welcome to EasyEDA. You should be able to import the Altium library for the device: [https://gansystems\.com/wp\-content/uploads/2018/01/GANSYS\_Altium\_Design\_Library\_Rev20170124\.zip](https://gansystems.com/wp-content/uploads/2018/01/GANSYS_Altium_Design_Library_Rev20170124.zip) into EasyEDA. It should be possible to get the PSpice model to run in the ngspice simulator that EasyEDA runs (but you will probably hit the max simulation time/dataset size limits first so you would be better using the LTspice model and simulating using LTspice). I recommend that you start here: [https://easyeda\.com/andyfierman/Welcome\_to\_EasyEDA\-31e1288f882e49e582699b8eb7fe9b1f](https://easyeda.com/andyfierman/Welcome_to_EasyEDA-31e1288f882e49e582699b8eb7fe9b1f) and go through all of it. :)
