WebFeb 9, 2024 · Time step too small means there is something changing so abruptly that SPICE can't find a solution. In LTSpice, you could try the alternate solver. Other things you can try are increasing pulse source rise and fall times, if applicable, adding parasitic capacitances, damping ideal inductors, removing parasitic inductances and reducing … WebFeb 2, 2014 · I tried your schematic in LTSpice. It failed with "Timestep too small" 1. The TLV431.asy symbol attributes are incorrect. The only attibutes values should be: Prefix=X …

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. Web#Battery - batteries, dry cells, Lithium* and Li-ion, Lead-acid, primary, rechargeable, etc. ecchy med term

WebMar 7, 2024 · if you give ltspice a recursive value, or a circuit that's unstable (like an op amp with the inputs swapped backwards) ltspice will try to find an operating point to start with, but the recursive nature of the calculation will keep ltspice from pinning one down, and so it tries to shorten the time steps to see if it can find a stable condition.
