Example: snsave
* load a circuit (including transistor models and .tran command)
* starts transient simulation until stop point
* store intermediate data to file
* begin with editing the file location
* to be run with 'ngspice adder_mos.cir'

.include adder_mos_circ.cir

.control
*cd to where all files are located
cd D:\Spice_general\ngspice\examples\snapshot
set noaskquit
unset ngdebug
set noinit
save vcc#branch 10
iplot v(10)
*interrupt condition for the simulation
stop when time > 500n
* simulate
run
* store snapshot to file
snsave adder500.snap
.endc

.END
