Ltspice time step too small time
WebAug 24, 2024 · I encountered several errors but got them solved with the help of many forums. The last error message was "Analysis: Time step too small; initial timepoint: … WebNormally, LTspice transient analysis starts at time = 0. You can edit the .trans simulation command’s “Time to start saving data” to delay saving until a later time of interest, thus decreasing your overall simulation time. Of course this assumes you do not need the initial data points, which are not saved.

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.
