[SOLVED] Setting initial conditions for simulation and timestep

Schematic Simulation (Ngspice)
1

As my schematic gets more complicated I’m starting to have problems running simulations. Ramping up
all the voltages from 0 helps, so I think the problems are finding a starting point.

How do I add spice statements like .ic V(V1)=5 into kicad simulations?

I do have voltages set by long time constants > 1s so when I run the same simulation in ltspice finding initial conditions can take minutes.

Also (in ltspice) I set the “minimum timestep” to a value, how does this compare to timestep in kicad?

Put it into a text box on the Eeschema canvas.

After adding a global net name, this worked a treat. Thanks.
