Would it be possible for you to add the code These work withall Qucs simulations except Harmonic Balance. Regarding the Qucs current and differential voltage probes. I read your latest post concerning Qucs probes and their use with ngspice and Xycewith interest. One advantage of using the approach show in the pdf is that it will work with bothngspice and Xyce. I also attach a basic SPICE netlist for the same test circuit. It is of course possibleto make this non-linear by changing the B I source equation. source to generate dQ/dt as the voltage across a 1 Henry inductance.In the example I have just shown a linear capacitor. Have a look at the attached pdf - this shows how to use the B type I =. Load a dataset in a single line of code, and use our powerful data processing methods to quickly get your dataset ready for training in a deep learning model. I agree with you that Xyce function ddt does not seem to work as expectedand indeed in a similar way to Verilog-A. Datasets Datasets is a library for easily accessing and sharing datasets for Audio, Computer Vision, and Natural Language Processing (NLP) tasks. csv for use with another software should be simple enough.I have found a solution to Qucs/ngspice/Xyce EDD charge problem. dat file that outputs the data in a text format, so using something like python to either directly process it, or convert to something like a. performs the required simulation actions, and finally produces a dataset. If it was something you really needed, I'd suggest writing a script to handle it. The Quite Universal Circuit Simulator (QUCS) 4 is an educational and open. I can't even find how to create these vectors, other than some basic creation tools, and then I can't find how to modify them after thier creation.Īs far as I can see, there's no sensible way to do what you need in QUCS natively. If there was a scripting option, or similar it would be doable, but I can't find one. Even then, you'd think that you could create a vector from these values using z = val1, val2. Then we could get all the values, but that would be super tedious as there's 100 steps (in my sim). all the elements in the first column, ie all the voltage values, for the different capacitor values, at the first time point Pr2.Vt - Pr2, the name of the probe, Vt voltages array Starting with our matrix of voltages, which is, we can get our values by ![]() Using y=stddev(Pr2.Vt) gets a value for all the datasets, whereas we want to do this on a per time step basis. What we need to create to get the graph is a vector stddevs of size Pr2.Vt is dependent on time, and Cval, so its size is. So time is an independent vector of size. QUCS creates its vectors with dependencies. On to the main challenge of plotting the Stddev of the voltage values for different capacitor values, over time. QUCS is case-sensitive, and "undefined" means I can't find that variable. Brought to you by: crobarcro, felixs, guitorri, in3otd, mike20brinson. Vout.Vt should work fine, but t should be replaced with "time". Qucs-help newbie help A circuit simulator with graphical user interface (GUI) Status: Beta. Just tells me that Vout is undefined and so is t. I haven't got the label Vout in this image, but I found no problems in using that. I noticed in your question you asked about sweeping the capacitor, but your image showed R2 set up to be swept so I changed this. Getting the capacitor sweep is fine, and plotting it over time works. I've had a pretty good go, and this is as far as I've got It's not a great answer, but I'm not sure QUCS can do this. ![]()
