Hi guys,
I have a very generalized question. My circuit freezes during simulation apparently without any warning, error or Convergence issue. I don't think that the circuit is the issue, because the simulation works fine sometimes but sometimes freezes without any change in the circuit. I have attached a partial image of my circuit (Lock in amplifier). Please can anyone suggest probable causes for my situation. Also if anyone has faced similar problems please let me know how did you take care of it
Thanks a lot!!
P.S: I am not at liberty to share the complete circuit.
