Simetrix-simplis-elite-8-20l Here

If you are designing a DC-DC converter, use SIMPLIS to generate AC Bode plots. It does this without needing small-signal averaged models, meaning you get the frequency response of the actual switching circuit.

The "Elite" version provides the full power of two distinct simulation engines: simetrix-simplis-elite-8-20l

Built specifically for switching power systems. Unlike SPICE, it models components as a series of linear segments, allowing it to find the "Periodic Steady State" of a switching power supply in seconds rather than hours. If you are designing a DC-DC converter, use
