2023年6月9日 · It is a variant of ngspice that has been seen to run much faster with some large circuits. The difference is that the mathematical core of the simulator, code to invert sparse matrices, has been replaced by a newer algorithm. Work is happening to add it as an optional feature of the standard version of ngspice. Discussion here.

2024年12月15日 · Hi Giles and Holger, thank you very much for taking the time to help out. I've updated the set c1/c2 lines and while the curve does show up with reset uncommented now, I still get only one curve where there should be five - please check out the image attached 1.png.

2023年8月2日 · So you may start ngspice repeatedly in control mode by ngspice netlist.cir controlsec.inc lib.inc where netlist.cir contains the invariable circuit netlist, controlsec.inc the .control section to run the simulation and prepare the output, and lib.inc contains as a single line the .lib statement to select the model like tt etc.. All three input ...

2014年4月29日 · Thanks Holger. Yes its working. Still effectively running ngspice in -b (batch mode) but having a control block to linearize now writes out a smaller rawfile at those tstep intervals, but as you say I do need the 64bit machine with lots of memory rather than my laptop.

2011年8月28日 · In ngspice (which is based on Berkeley Spice 3) you can only plot currents through (independent) voltage sources. These are the only currents that appear in the circuit equations SPICE works from. In an interactive Spice session or from a special block in the script (see also this question ) you can use expressions like (v(1)-v(2))/1k when the ...

2019年7月6日 · No, ngspice does not know anything about the EXCEL format. You might use the wrdata command to write out your data in a tabular form, best done with ngspice-27 that allows playing around with set wr_singlescale set wr_vecnames option numdgt=3
