Can I request for SIMPLIS file that is support run pop analysis
Hi Yong,
That model doesn't contain POP trigger on schematic.
If using STEADY_STATE model, make sure you have the settings for model set like this:

Hi Yong,
If you are trying to add bode in Simplis, you will need:
a. Settings as:
b. Pop trigger, either of the below can work:
Typically connected at SW node
c. Bode probe with AC source:
Typically connected same as EVM bode -> CHA and CHB
You can get the needed setting and bode tools from other devices that offer loop response model like TPS54J060: https://www.ti.com/lit/zip/slvmdc5 for example.
Also to note: if sim fails, try running Transient Analysis first to set component conditions, and then AC+POP Analysis. Do this every time you re-open model or make a change to it.
Other ways to analyze bode:
- Using EVM
- Use WEBENCH sims:
- A bit less accurate, device calculator https://www.ti.com/tool/download/SLURB05 has bode calculation section

Eileen
