Is there a way to get progress from ngspice simulations? There doesn't seem to be any verbose option... I guess it gives you the time on transients, but nothing about loading large circuits.

Try adding this command to your runs:

.options ACCT

Hrm, I think that is shown normally, at least in batch mode.

Cool

Looks like it does provide some additional output: Number of lines in the deck = 646923 Netlist loading time = 26.332 Subckt and Param expansion time = 53.804 Netlist parsing time = 12.01 Nominal temperature = 27 Operating temperature = 25 Total iterations = 47835 Transient iterations = 47835 Circuit Equations = 15415 Circuit original non-zeroes = 111742 Circuit fill-in non-zeroes = 26476 Circuit total non-zeroes = 138218 Transient timepoints = 19386 Accepted timepoints = 19384 Rejected timepoints = 2 Total analysis time (seconds) = 1657.99 Matrix load time = 825.709 Matrix synchronize time = 0 Matrix reorder time = 1.604 Matrix factor time = 623.58 Matrix solve time = 67.26 Transient analysis time = 1657.35 Transient load time = 825.692 Transient sync time = 0 Transient factor time = 623.58 Transient solve time = 67.26 Transient trunc time = 57.663 Transient iterations for the last time point = 0

@Matthew Guthaus I wouldn't say that I'm an expert with ngspice. But I used ELDO extensively.
