Example of DWS simulation in Spicy SWAN https://www.ischematics.com/webspicy/report.py?RCODE=30616551605602717671as

Hi Piero, It could be interesting to add DWS to extend the high speed simulation capabilities of EasyEDA but if I recall correctly, your DWS code is proprietary rather than Open Source so it would not simply be a matter of picking up a copy of your source code. It would be good if DWS could integrate with PCB design for Signal Integrity and for EMC. May I suggest you contact Dillon at the **Business development/cooperation:** address on the **Contact Us** page? https://easyeda.com/contact

Hi Andy, yes, you recall correctly. DWS is for sure the best solution for pcb pre and post-layout SI and EMC simulation and is complementary to ngspice as general purpose simulator: https://sourceforge.net/p/ngspice/discussion/133842/thread/8f20bc1b/ https://sourceforge.net/p/ngspice/discussion/133842/thread/363a66f8/?page=13 Thanks for the link

I've just sent the message to Dilllon.
