Qucs qucsator simulation, Ngspice, Xyce and SPICE OPUS simulations result in three different datasets: RCL.dat — for Qucsator; Already using ngspice in Fedora Linux. There’s one thing this series is missing, which doesn’t surprise me because it’s practically hidden. Ia percuma untuk mendaftar dan bida pada pekerjaan. But, for RF (and other small signal or simple linear circuits) QUCS really shines, since it was written from the ground up to be able to RF work. In a simulation, you often pull component values out of thin air, so you don’t bother with part numbers and footprints. Share your experience with using QUCS and LTspice. Shuang Peng wrote a reply on Quadruped robot BAI. Join the LTSpice users group on Yahoo. I don’t know what gEDA uses but the qucsator engine used in QUCS is terrible for transient simulations such as that, and while ngspice is better LTspice seems to be a good bit faster. From there, you can export a netlist for gEDA PCB, pcb-rnd or even KiCad. You must understand that if you Harm LTSpice in any way, you will LOSE many EE’s as a preferred supplier. Click the graph window then hit file > export. After that simulation has finished you can view the simulation results on a presentation page or window. I think I’m off to Google now!

Everybody who wants to help is called to have a look into the support section. Plus, there is a large community dedicated LTSpice users who support the product and enhance it in many ways. I apologize if this is off-topic for the development list, but I thought it was a better place to ask the question. LTspice’s spice engine is really very good (way better than the open source spice implementations out there) at simulating the transients that come up in switchmode power supply design. Oh no! The only thing I wish QUCS had was a better way to do optimizations. Then qucsator fails to keep the ports connected when flattening the netlist. LTSpice awesome. Qucs adds an appropriate suffix to each simulator dataset name in order to avoid name clashes and mixing up results from different types of simulation. Some styles failed to load. In the RCL test example the Qucs schematic is named RCL.sch. Support section added 1st August 2016 This homepage now contains a list with tasks that are needed for the development of this project. I wonder if there is a good way to convert between LTSpice and KiCad yet. They aren’t the same kind of schematics. jim liked Wireless solar-powered sensor node.

I design RF stuff for a living these days. LTSpice imports (unencrypted) SPICE models from other manufacturers fine. I also recommend QUCS for simulation. I thank LTC for making LTSpice freely available (albeit proprietary). Diseño y simulación de circuitos eléctricos integrados. Thank You ! Por ejemplo podemos graficar la tensión de 'Gate '. Al The only other tool I have used that I liked as much as QUCS was Agilent’s ADS (licenses starting at about $10k) in terms of ability to quickly do RF design work. The Spice model is just a text file, and will work with most other variants of Spice. It really bugs me though that some tools are good for simulating and others are good for designing PCBs but there doesn’t seem to be much integration between them. Circuit Simulator In my many years as an EE, LTC,has been (reasonably) friendly to designer/developers at any level. Tim Rightnour has added a new log for DI Monitor. in QUCS and make a comparison between QUCS and PSpice on the complexity and usability of the programs. It is a front-end for openEMS FDTD engine. I was looking at the QUCS screenshots, and I saw the Peltz Oscillator example. In addition, PCB-RND can save in KiCad layout format. Very easy to use. Other interesting LTspice alternatives are QUCS (Free, Open Source), Xcos (Free, Open Source), OpenModelica (Free, Open Source) and Ktechlab (Free, Open Source). It seems you need an indepth knowledge of the underlying math to even get it to simulate in the first place. There are some cases where LTSpice is the highest performance circuit simulator out there but as others have pointed out, they don't go out of their way to support 3rd party models so it is not the best choice for simulating non-LT parts. That’s another thing I wanted for a long time but haven’t actually checked on for a while. Of course, the first few cover simple things like voltage dividers just to get your feet wet. A real schematic has connectors, LEDs, microcontrollers, decoupling caps, and most of all, part data like part numbers, etc. Qucs is an integrated circuit simulator which means you are able to setup a circuit with a graphical user interface (GUI) and simulate the large-signal, small-signal and noise behaviour of the circuit.
