a behavioral model to measure a SMPS like buck converter's loop

Hi,

I am wondering if there is a behavioral model to plot a SMPS like buck converter's loop in transient simulation like below website.

Thanks!

The link you shared shows that the simulator in question supports ".fra" as a new analysis type. This is outside the scope of a hardware description language like Verilog-AMS, which does not require a simulator to support specific analysis types.
Probably one could develop a model that would be helpful in generating the plot, but you'd need some extra code, either in the simulator or in a post-processing tool.

If at first you do succeed, STOP, raise your standards, and stop wasting your time.
