What was your problem exactly? I got the same result each time , as if the alter statement was neglected and the time column from the analysis appeared in the first column. thanks for your solution, it works like a charm kind regards, Hugo

I'm trying to get the results of a measure statement using consecutive values for a component. As a trivial example I made a simple voltage divider and try to measure the output amplitude (at node 2) of it. My input file, which does not give me the expected result, looks like this: test param vin 1 0 dc sin(0 1 1k) r1 1 2 1k r2 2 0 1k .control set filetype ascii option unixcom set nobreak tran 10u 2ms 0 10u shell rm $HOME/resultsmultipleruns.dat set appendwrite set filetype=ascii foreach rvar 100...

Maybe you could use a square wave (using a PULSE-source) with a 50% duty-cycle?

Dear Marcel, Thanks for the explanation. Do you think I'd better put my request concerning "the little window" on the Kicad-forum? kind regards, hugo

Marcel worte: I realize now that you are running from within KiCAD. I guess that environment does not show a window where you can see the feedback from ngspice stating that it is still running: during a .TRAN it prints the scale value (sim time) to the display every 0.5 - 1 (wall-clock) seconds. Do you mean by scale value (sim time) the "current" simulation time? and is this the same as that "reference value"? I looked up "reference value" in the ngspice-manual and only found this (which is not related...
