So far, I have used this software for simulating DC and AC circuits for DC simulation and AC simulation.
QUCS SIMULATION INSTALL
To install on windows, use below link to download the executable file which can directly be used without installation. Use following commands to install QUCS on debian based Linux operating systems such as ubuntu, mint, debian, etc.
In Linux, I used this software on Ubuntu 16.04, 18.04 and 20.04 and in Windows, I used this software on windows 7. I have used this software both on windows and Linux operating Systems.
QUCS SIMULATION MANUAL
Some of them areĪs per the manual of QUCS it has many features as listed below: There are plenty of circuit simulators which have different features and advantages. This in turn can reduce the total cost of the product. This method will reduce the time and cost involved in manufacturing process. If result of circuit simulation is not as per the expectation, then design can be changed and circuit can be tested again to see the results. Circuit simulators provide virtual components whose behaviour is almost similar to that of physical components. Circuit simulation is used to check the correctness of the design. Normally this method is used after the design of a circuit or system and before the manufacturing of the physical circuit or system. Before discussing this software lets discuss little bit about circuit simulation.Ĭircuit Simulation – It is a method to verify the behaviour of the electric or electronic circuit or system, without using actual or physical device. QUCS stands for Quite Universal Circuit Simulator. In searching such a software for circuit simulation, I came across this software. I would always prefer to use open-source software for doing my work. Some of these softwares are open source and some are proprietary. Now, if you want to play around with it, get the Qucs project files.There are many software to simulate given analog or digital circuits. frequency and phase response of the filter. Once you simulate your design you are presented with a Bode plot, i.e. This is necessary because otherwise the system of equations would not have a unique solution. Note, that the capacitor’s values are fixed to 100nF and 200nF respectively. The component values are then calculated using the standard equations.
You choose the desired cutoff frequency of the filter and enter it as the variable cutoff in an equation. Let’s have a look at the lowpass version: Received this info from qucs-s main developer on the github page. Use of ngspice is the big improvement moving from qucs to qucs-s. Apparently this is necessary for ngspice to work. It comes in three varieties: lowpass, highpass, and bandpass. In qucs-s you need to label each simulation a 'Transient' solution rather than a DC solution as in qucs. In this post I present a simple Qucs schematic for designing Sallen-Key Butterworth filters. One of its many nice and useful features is the ability to write equations so you can calculate all kinds of stuff from simple linear equations up to Fourier transforms as part of the simulation. It’s free and sports a nice graphical schematic capture interface. Qucs, short for Quite Universal Circuit Simulator, is as the name suggests a simulation package for electronic circuits.
