Hi, :
I'm sorry, I have reduced the transfer gain to almost 1+/- 2u, which I thought the +/- 2u (1e-6) shouldn't take any effect to the feedback, at least not result in a +/- 0.03 V variation. The example isn't flyback, it includes some properties , I forgot to simplify the transfer gain to single "1", maybe tomorrow. But if this means, there aren't any known issues about the BV,BI behaviors.
Is it true, not any limitation found yet ?
Thank you very much.

Hello, :
May I ask, is there any limitation when using the behavioral source (bv, bi) ? I found it seems there are some differences in my simulations, when I tried to add the BV behavioral voltage source to do some math manipulation of a feedback signal in a application schematic (eg: flyback, etc), before adding the BV into the feddback, the simulation ran quite normal as expected, but after adding the BV to the feedback, the "FB" signal seems having larger swing amplitude which makes the output to switch separated in chunks (many time durations), the only thing I doubt caused those differences is the timestep, the simulation without adding the BV model, ran into smaller timestep while the one with BV didn't, the worse resolution of the simulation made the errors.
So , may I confirm, what's the difference(/limitations) when using BV in those kinds of applications ?
Thank you very much
Have a nice day!
