Gui in ltspice for mac12/20/2023 I'll let the devs know about this thread in case they want to chime in.ĭrawing, amending and altering, moving, changing schematics is 4x to 10x faster in LTSpice compared to Eagle. The underlying engine is extremely powerful now we are just making sure that we expose that power in a way that is easy to use and allows you to get your analysis done quickly. STEP directive supported yet which is the one you would need for that type of analysis. ![]() PARAM spice directive but we don't have the. We currently don't support parametric analysis, we do have support for the. An up-down drag will let you zoom in on the amplitude axis. A left-right drag will zoom in on a section of the frequency(time) axis. Just in case you were not aware, a left-click and drag will zoom in on the waveform. We know this is an area that needs some additional work and our developers are on it.ĥ. Pretty much the same way you would have to do it in real life. In order to measure current you would have to break a net and insert the ammeter component at the break. We do have a current probe currently, it's the ammeter component in the ngspice-simulation.lbr that now comes with EAGLE. Also an excellent suggestion and one that our developers are also aware of, so thank you for the bump.Ĥ. Stay tuned as we continue to improve the SPICE interface in EAGLE.ģ. This is a good suggestion and one that has been duly noted. Set the AC input voltage to be 1V in this way your Vout waveform becomes your transfer function plot, because Vout/Vin = Vout/1 = VoutĢ. However, for your specific scenario the solution is very easy. Currently you can not display equations of the various waveforms. Thanks for coming to our forums and for ordering your suggestions in a nice organized way. I think this would be a lot easier to implement if it were a proper window and not a modal dialog. We definitely need explicit current probes and it would be much better if the automatic current probe feature were turned off by default (or just removed). Yes! I ended up getting very frustrated by the current waveforms always being present. Personally I think this is the wrong design choice for this tool and I hope they change this because modal dialogs for complex tools just makes life unnecessarily cumbersome and wrote: This issue is caused I think because rather than making the simulator its own window with forward/back annotation to the main design, it's been implemented as a modal dialog which lock you into its focus and removed any ability to go to another EAGLE window and do something useful. Currently they get added to your library files but then that will likely cause compatibility issues with pre-SPICE versions of wrote: Yes the method of finding and including models I find is currently a bit disjoint, I think they could do with investing more time into tools for the management of the various models. I've not experimented enough with this tool yet to know if there is a way but if this isn't possible currently then it's definitely a good wrote: I think that, by default, only the probes set by the user should be displayed.īy the way, how do you do parametric analysis? E.g., vary a resistor value in an interval and do a frequency sweep for each value, and plot all curves on the graph. I am not interested in plotting the currents and on each analysis I have to manually disable the current plots for each probe placed on the schematic. Please disable displaying currents by default and divide the probe in Voltage Probe and Current Probe. E.g., in Orcad Pspice you can place probes after doing an analysis.Ĥ. Allow the possibility to place probes after analyzing the circuit.Īfter an analysis, if I want to see the voltage in a different node than those configured I have to close the simulation window and redo the analysis, which is not OK, especially if it takes a relatively long time. Allow the possibility to import LBR modes directly Īlmost all models I find on the Internet are for PSpice I had to change the extension of a model file from. ![]() frequency, but I do not see a way to plot Vout/Vin in an AC sweep analysis.Ģ. Allow the possibility to display equations, e.g. I have a few suggestions I consider would be very helpful if implemented:ġ. Hello! I'm using EAGLE 8.4.3 to simulate an active circulator.
