Problem with the simulationDt value

SPIS
1

Hi, I have a problem with a simulation I’m running. When I’m in the “Simulation running and monitoring”, whatever value I chose for “simulation Dt”, SPIS starts to use as Dt some very small values, of the order of 10^-7 or 10^-8. Any idea of where my error could be?

Many thanks in advance.

I solved the problem by setting a bigger Csat value. The answer was in the “How to control NUM from UI in SPIS 5” manual where I found the sentence “The smaller the SC capacitances, the faster the SC dynamics, the smaller this time step must be.”.
