Hello. I am trying to do an ac analysis and sweeping the supply voltage and temperature at the same time. I want to have a vector of arbitrary voltages and temperatures, do the simulation do a plot in xterm and save the data as raw file for the xschem graph. When i run the attached code i only get one simulation, I should get three for my current inputs. Can somebody point out what is wrong?

See this (ngspice manual chapter 17.6.4 Foreach - End) or the tutorial at https://ngspice.sourceforge.io/ngspice-control-language-tutorial.html#nloops :

Thank you very much! Where in the loop should i put the write raw file and appendwrite to save all the plots in the same file?

How di you added the Tab for netlist?
