Hi Team,
My customer wants to use SPICE model of ISO224 so he converted from TINA-TI model on TI.com followed by the instruction of this video.
(symbol was generated from ".SUBCKT ISO224X VCAP IN VDD1 GND1 GND2 OUTN OUTP VDD2")
However, error message "Voltage source E:U1:INPUT:BIAS:U20:U1:GND is shorted making an over-defined circuit matrix" showed and couldn't run AC analysis in SPICE simulator.
After looking up for the reason, it seems error occurs from following 3 commands. After customer commented out these 3 commands, though the error still occurred but he was able to run AC analysis.
Could you help take a look what may go wrong here? Please let me know if you need any more information. Thanks. (I attached the full information after converted to SPICE as below.)

Hi Jo,
I will take a look and consult the team on this error. Please keep in mind that the holidays are coming up in the US so our responses may be delayed.
Hi Smith,
Want to follow up if there's any update for this inquire? Thanks.

Jo
Hi Jo,
I'm not immediately sure what would cause this error. Can you please ask the customer to share a screen-shot and/or simulation file of their circuit?
