Thank you very much for your suggestion ¡ª you solved a problem that had troubled me for weeks. The convergence is indeed much better now. However, there are still some aspects of the model that puzzle me.
When my input B is a 50?Hz sine wave, the simulation only converges when the delay "tau" is set to 300?ns. If I reduce tau to 200?ns or smaller, the simulation still gets stuck at some point. Moreover, when I try to increase the frequency of B, tau = 300?ns no longer works. This behavior seems to make the model not very robust across different conditions.
Do you have any insights into what might be causing this?

Again, thank you so much for taking the time to help!
