Weihao,

Your original post was TPS54218 and TPS54160. The two links above are for TPS54331 and TPS54320. Can you elaborate and tell me the detailes steps of the procedure that is causing your issue?

Weihao,

I am going to assign this to the Webench team. It is not really a part issue.

Hi Weihao,

Thanks for your feedback.

This is a bug specific to the TPS54160 device in the tool. You should be able to update the VIN value for both devices under "Sim" -> "Bode Plot" simulation type. I will alert the team of this issue and we will fix it as soon as possible.

Regards,
Amod
