Summary: Review Request: GspiceUI - A GUI to freely available Spice Electronic circuit similators https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=247402 ------- Additional Comments From cgoorah@xxxxxxxxxxxx 2007-07-10 19:41 EST ------- (In reply to comment #5) > (I guess that Chitlesh know much and much more than me > about gEDA related things. He maintains most of gEDA related > packages on Fedora) I wrote a simple scenario, a RC circuit. Below I'll describe how Mr Joe or Miss Jane will use this gspiceui. We will simulate the charging process of a capacitor. http://photos1.blogger.com/blogger/1480/1470/1600/fedora-xcircuit.png http://tux.u-strasbg.fr/~chit/gspiceui/cir1.ckt describes the spice netlist of the RC circuit with a different voltage source. We will choose our own voltage source. mkdir gspiceui_test copy cir1.ckt to this directory gspiceui_test cp cir1.ckt cir2.ckt We will work with this cir2.ckt leaving cir1.ckt as a backup. launch gspiceui gspiceui& gspiceui uses either the gnucap or ngspice engine for simulation. First of all, we will start with ngspice, because I maintain it, after if you want you can retry doing the procedures with gnucap. Options -> ngspice (and wait a few secs, till gspiceui configures itself) File -> Open -> choose cir2.ckt now, choose "c" under "component" and choose "Transient" then, change "stop time" to 1 sec. ONE SECOND. You should see the following screenshot: http://tux.u-strasbg.fr/~chit/gspiceui/gspice1.png then choose "vin" at "Voltage Source". Next to it, is a button called "setup ...". Click on it. Fill the dialog as shown in this screenshot: http://tux.u-strasbg.fr/~chit/gspiceui/gspice2.png and hit OK Then: Simulate -> Create you should see this screenshot: http://tux.u-strasbg.fr/~chit/gspiceui/gspice3.png Then: Simulate -> Run you should see this screenshot: http://tux.u-strasbg.fr/~chit/gspiceui/gspice4.png Till now, without gwave, the user can't do more. Hence the data you saw on the screenshot "gspice4.png", is pretty much useless, unless Mr. Joe or Miss Jane knows "LabPlot". LabPlot is already on fedora repositories. (thanks Mamuro for reviewing that package :)) yum install LabPlot then launch LabPlot. File -> Import "cir2.ngspice.tr" As you can see gspiceui stored the simulated data in the file "cir2.ngspice.tr" see http://tux.u-strasbg.fr/~chit/gspiceui/gspice5.png And hit OK: you will see the data properly filled into a spreadsheet.: http://tux.u-strasbg.fr/~chit/gspiceui/gspice6.png Now we will plot the simulated data, which gspiceui should have done if we have gwave. on labplot, Spreadsheet -> Plot -> 2D Plot (XY) That's it, you should see the charging curve: http://tux.u-strasbg.fr/~chit/gspiceui/gspice7.png http://tux.u-strasbg.fr/~chit/gspiceui/out.lpl you can do the same way with the "gnucap" engine. copy cir1.ckt to cir3.ckt and start the hold process again. I did it I'm satisfied. In this example, we started the simulation with a netlist (a simple text file), but there is another way to do the simulation (from a schematic). If the schematic is imported into gspiceui. gspiceui converts the schematic into a netlist with the help of gnetlist (from geda-gnetlist). Hence the package requires geda-gnetlist. I'm uncertain whether gspiceui should requires: * gnucap or * ngspice or * gnucap and ngspice. I'll vote for both! -- Configure bugmail: https://bugzilla.redhat.com/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. _______________________________________________ Fedora-package-review mailing list Fedora-package-review@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/fedora-package-review
