Quite Universal Circuit Simulator ... On Qucs 0.0.19 (development version), I get several errors from the Spice to Qucs converter, saying "behavioural Exx source ignored". - ra3xdh/qucs_s About this release This is the third release of Qucs-S, a spin-off of Qucs with SPICE simulation kernels support. . . The most popular Linux alternative is Circuit Simulator, which is both free and Open Source.If that doesn't suit you, our users have ranked 35 alternatives to QUCS and ten of them are available for Linux so hopefully you can find a suitable replacement. . Copy link Contributor ... some spice models behave weird during events, maybe the switch does that too? Installation of Qucs is explained in this manual. To add the package repository and install Qucs, use the following sequence of commands: sudo apt-add-repository ppa:qucs/qucs sudo apt-get update sudo apt-get install qucs Awesome! Qucs-S is available as an AppImage which means "one app = one file", which you can download and run on your Linux system while you don't need a package manager and nothing gets changed in your system. To make the process transparent, and indeed straightforward for users, the conversion stage in simulating SPICE netlist files 5 has been automated via the Qucs GUI simulate command (F2 key). . To install Qucs in Ubuntu. . . See https://ra3xdh.github.io/ for details. . . . However, there are still significant gaps in the Qucs-0.0.19S simulation capabilities (for example no SPICE 3f5 .PZ simulation yet) and model coverage (for example the number of … . . I also tried the same version and input file on Ubuntu, same result. 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. 8 Modelling the 555 Timer261 8.1 Introduction. . . . After that simulation has finished you can view the simulation results on a presentation page or window. . Quite Universal Circuit Simulator vs. PSpice This white paper investigates the Quite Universal Circuit Simulator (QUCS). . The program is an open source circuit simulator that is capable of doing simple analog simulations. It is used to create a circuit with a graphical user interface. Qucs-S is spin-off of Qucs. . Quite Universal Circuit Simulator (Qucs) is a free-source electronics circuit simulator software. Linux merlin 4.15.0-34-generic Qucs/qucs#37-Ubuntu SMP Mon Aug 27 15:21:48 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux. . There are many alternatives to QUCS for Linux if you are looking to replace it. AppImages are single-file applications that run on most Linux distributions. . Qucs 0.0.17 packages are available for Ubuntu versions 13.04 (Raring), 12.10 (Quantal), and 12.04 (Precise). another idea: if a dc analysis does not converge, the "result" might look plausible. . Usage. . . You cannot edit the SPICE block's symbol, though, so it recommends putting the SPICE subcircuit inside a QUCS subcircuit. Supports spice simulators. With the first release of spice4qucs, as Qucs-0.0.19S, this aim has largely been achieved. It replicates the large-signal, small-signal and noise behavior of the circuits. . . . This is my spice file, … . 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. After that simulation has finished you can view the simulation results on a presentation page or window. .
