However, even switching from an averaged model to a switched model is not straightforward, since the initial states are not the same. Therefore, the switched model cannot directly inherit an already simulated state from the averaged model. I would also like to mention that averaged models are mainly intended for real-time simulations, as in PLECS, and possibly for long mission profiles. For this reason, … --- _[View the full topic](https://forum.plexim.com/t/using-ideal-and-spice-models-in-the-same-plecs-simulation/2916)._
