LM61460-Q1: Converging fail when simulation

Alex Yeh

Hello team,

I am facing a converge fail issue during my simulation work. Could you help me check what is the cause and how to solve it? Thanks.

Hello

I will move this to our SPICE model group and see if they can help.

Thanks

Hi Alex,

The simulation profile indicates that you want to run bode plot simulation. Is that correct?

If so, I would suggest working off of the average model which should enable small signal anlaysis simulation.

The transient model is generally used for DC (time domain) sweep.

Please navigate to the average model (shown below) and modify the existing file to match your desired component selection and run the simulation again.

Regards,

Jimmy

Hi Alex,

Sounds good. Please keep me posted if there is any remaining issues.

For now I will close this thread since I believe using the average model should address your bode plot simulation concerns.

Jimmy
