I want to simulate a DC motor driver like MIC4606-1 in SIMetrix/SIMPLIS software. The microchip provided only the SIMetrix model of MIC4606-1( Transient model: https://www.microchip.com/en-us/software-library/analogsimmic4606 )

In stability point of view, I have to simulate my circuit in SIMPLIS environement and not SIMetrix, and I need the AC model of MIC4606-1 that microship does not provide.

Is there a way to converte the SIMetrix model to SIMPLIS model?

Is there a trick to use the SIMetrix model for AC analysis ?

  • \$\begingroup\$ I don't think you can translate complex subcircuits to SIMPLIS. Plus, the subcircuit is encrypted which makes it an even bigger pain to deal with. Have you thought about possibly the opposite approach? Use a transient simulation in SIMetrix to determine stability via using an averaged model for your switching element(s). C. Basso talks about this extensively on his SPICE page: cbasso.pagesperso-orange.fr/Spice.htm \$\endgroup\$
