I have accomplished the stability simulation for DC-DC converter using PSS/PSTB. I will post a short file  for those who concern. 

Thanks in advance  for sharing

Hi all,

If you want to have the file, please send me a message: [email protected]

BRs,

I'd like to attach the guide for simulation here. Hope it helps!

BRs,

Ha

Thanks for sharing the guidance, it's really helpful.

Thanks Dr. Mao. Happy to know you can use my share.

PSS/PSTB is the right approach!! I have used in DIGOTA also. The trick is always calculate the tstab !!

Thanks Toledo. Could you share the related materials (paper, document, technical report etc) for this technique? It'll be nice.

Regards,

This is good . Unfortunately it looks like in Analog Mixed Mode the PSS simulation is not available, so when using digital blocks in the loop chain will be unusable. Or somebody has a solution for that?

Theoretically should be possible since as far as I understood the PSS is based on an analysis of voltages / currents on a cycle by cycle basis, so would ignore the digital values and look only at the analog quantities and extract the same info.

P. Toledo , we can let simulator to choose "decide automatically"

Miao Tang , yes indeed. But depending on the design, you have to at least give the first guess to the tools!!
