Hello all! I have a perhaps rather odd question for ngspice: I am running a loop of transient simulations and I was wondering if there is a way I can force ngspice to clear the data after I write the data out? I would like to run longer simulations (without resorting to python), but I’m running to the memory constraint of my machine. I have looked at

unset

and

unlet

attempting to release a whole plot and

unset *

but that doesn’t seem to work. Do you have any ideas? Thanks a lot!

I think you may want to use

destroy

@yrrapt That’s it! Thank you!!

Also ensure the following lines are present in the .

spiceinit

file that must reside in the directory where the simulator is running (and where netlist is created):

set ngbehavior=hsa

set ng_nomodcheck

The second line in particulsr reduces memory usage dramatically, even by 10x on big designs.

@Stefan Schippers Thank you! Is there a way to verify that ngspice has loaded .spiceinit?
