Ltspice time step to small
WebApr 12, 2024 · Hello jqjiang, The simulation will run even without the capacitor, if you set a maximum time step .tran 0 4m 0 0.1u It's not necessary to add an extra capacitor in your real circuit, because teh MOV itself already has about 1nF capacitance. Sometimes we add a small capacitance in the simulation, if we problems with convergence. Be aware that any … 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 ...

WebOct 24, 2011 · Hello, All these multiplier models make a lot of trouble. 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. WebNov 9, 2011 · Activity points. 258. Try to decrease the step ceiling. Note that your command. .TRAN 1m 1 uic. is not optimal: the first number 1m has no effect to the simulation run; you have not set the step ceiling, thus it is defined automatically as 1/50=20ms and it is too high. Try the following: .TRAN 0 1 0 1m uic. Then it works in PSpice.
Web1. "Time step too small" is usually the consequence of a "shock" or discontinuity on your models. It indicates that the solver could not achieve the desired voltage/current precision with a reasonable time step in the differential equation solver. – Edgar Brown.
