Sometimes we add a small capacitance in the simulation, if we problems with convergence. Be aware that any …
Ltspice time step too small time
Did you know?
WebAnswer: I have seen this occur when combinations of components give both very small and very long time constants within the same analysis. So if a model has say an RC combination with a very small time-constant then the time step has to be made very small to track changes in these components. If ...

Solution for your circuit: Either only use positive voltages on X1 or exchange the. connection on Y1 and Y2 when you use negative voltages. You also need the Alternate solver for this circuit. Control Panel -> SPICE -> Solver:Alternate.
