Is there a way to speed up LTspice simulations?

Try the following:

1. In a .tran statement try skipping the initial operating point solution

2. In a .tran do not specify the Maximum Timestep (above notice the blank field).

3. In a .dc analysis do not specify the increment of the 1^st source, below. You do have to specify it for the other sources (it’s 250 mV for the second source below).

4. For very large simulations use a .save to limit the amount of information stored on the hard-disk. For example use the directive .save V(out) V(in) where out and in are labeled net names.

5. Try using the alternate solver, below.
