Simulator - designer of electronic circuits "Beginnings of electronics"

There is a very interesting program, which is a simple simulator to demonstrate the work electrical circuits and work measuring instruments. Its convenience is not only in visibility, but also in the fact that the interface is in Russian. It allows you to model very simple circuit diagrams. The program is called "Beginnings of Electronics". Link to it at the bottom of the page, video channel of Mikhail Mayorov.

The program works from Windows 98 to Windows 7. The interface looks like this.

Below is the drawing printed circuit board, but for us the socket with the breadboard is of the greatest interest. Top control buttons: load circuit from file, save circuit, clear breadboard, get multimeter, get oscilloscope, show part parameters, part status, reference, (summary of electrical concepts), small list laboratory work for their independent implementation, instructions for using the simulator, information about the authors, exit from the program.

Watch the video on how the circuit simulator works.

What can be assembled on a circuit simulator?

On this simple simulator, you can collect quite a lot of interesting things. First, let's model a regular flashlight. To do this, we need a light bulb, two batteries and, of course, all this will need to be connected with jumpers. Well, what is a flashlight without a switch and a light bulb?

Double click to bring up the battery parameters window. On the tab that appears, we see voltage, internal resistance, showing its power, minipolarity. In this case, the battery is eternal.

When the circuit is assembled, we press the switch twice and for some reason the light bulb burns out. Why? The total voltage of the batteries connected in series is 3 volts. The default light bulb was 2.5 volts, so it burned out. We put a 3-volt light bulb and turn it on again. The light bulb glows well.

Now take a voltmeter. Here his “palms” light up. These are measuring sticks. Let's move the probes to the light bulb and set the measurement of DC voltage with a limit of 20 volts. The monitor shows 2.97 volts. Now let's try to measure the current strength. To do this, take the second multimeter. The device connected to the circuit showed almost 50 milliamps.

Almost like a real multimeter, you can measure many parameters. There is also an oscilloscope in the simulator, which even has an adjustable beam brightness. In addition, there is a rheostat, you can move the engine. There is variable capacitor, shunts, heating stove, resistors, fuses and more. Unfortunately, there are no transistors in this simulator.

Multisim - electrical circuit designer

Multisim is one of the advanced programs for professionals and just people who are fond of radio engineering. The program can design a huge set of types of electrical circuits. If you want to simulate your electronic ideas and check their performance, then download the Multisim program. On the Internet there are options in Russian.

Program functions

Introduction to Multisim

Currently, there is not much open-source CAD. Nevertheless, among the CAD for electronics (EDA) there are very worthy products. This post will be dedicated to open source electronic circuit simulator. source code. Qucs is written in C++ using the Qt4 framework. Qucs is cross-platform and released for Linux, Windows and MacOS.

The development of this CAD system was started in 2004 by the Germans Michael Margraf and Stefan Jahn (currently not active). Now Qucs is being developed by an international team, which includes me. The project leaders are Frans Schreuder and Guilherme Torri. Under the cut, we will talk about the key features of our circuit simulator, its advantages and disadvantages compared to analogues.

The main window of the program is shown in the screenshot. There, a resonant amplifier is modeled on field effect transistor and obtained oscillograms of the voltage at the input and output, as well as the frequency response.

As you can see, the interface is intuitive. The central part of the window is occupied by the circuit being modeled. Components are placed on the schematic by drag and drop from the left side of the window. Modeling views and equations are also special components. More details on the principles of editing schemes are described in the documentation for the program.

The Qucs schema file format is XML-based and comes with documentation. Therefore, the Qucs circuit can be easily generated third party programs. This allows you to create circuit synthesis software, which is an extension of Qucs. Proprietary software typically uses binary formats.

We list the main components available in Qucs:

1. Passive RCL Components
2. Diodes
3. Bipolar transistors
4. Field effect transistors (JFET, MOSFET, MESFET and microwave transistors)
5. Ideal op amps
6. Coaxial and microstrip lines
7. Library Components: Transistors, Diodes, and ICs
8. File components: subcircuits, spice-subcircuits, Verilog components

The Component Library uses its own XML-based format. But it is possible to import existing component libraries based on Spice (provided in datasheets for electronic components).

The following simulation types are supported:

1. DC operating point simulation
2. Modeling in the frequency domain on alternating current
3. Simulation of the transient process in the time domain
4. S-parameter modeling
5. Parametric analysis

Simulation results can be exported to Octave/Matlab and post-processed there.

Qucs is based on a newly developed circuit simulation engine. A distinctive feature of this engine is the built-in ability to simulate S-parameters and SWR, which is important for the analysis of RF circuits. Qucs can convert S-parameters to Y- and Z-parameters.

The screenshots show an example of modeling the S-parameters of a broadband high-frequency amplifier.

So, distinctive feature Qucs is the ability to analyze complex frequency characteristics(CCH), plotting on the complex plane and Smith charts, analysis of complex resistances and S-parameters. These features are not available in proprietary MicroCAP and MultiSim systems, and here Qucs even outperforms commercial software and allows you to get results unattainable for electronic circuit simulators based on Spice.

The disadvantage of Qucs is the small number of library components. But this disadvantage is not an obstacle to use, since Qucs is compatible with the Spice format in which models are given. electronic components in datasheets. Also, the simulator is slower than similar Spice-compatible simulators (eg MicroCAP (proprietary) or Ngspice (open-source)).

We are currently working on the ability to provide the user with a choice of engine for circuit simulation. It will be possible to use the built-in Qucs engine, Ngspice (spice-compatible console simulator similar to PSpice) or Xyce (simulator with support for parallel computing via OpenMPI)

Now let's look at the list of innovations in the recent release of Qucs 0.0.18 promising areas in the development of Qucs:

1. Improved compatibility with Verilog
2. Porting of the interface to Qt4 continues
3. Implemented list of recent open documents in the main menu.
4. Implemented export of graphs, diagrams to raster and vector formats: PNG, JPEG, PDF, EPS, SVG, PDF+LaTeX. This feature is useful when preparing articles and reports containing simulation results.
5. Ability to open a schematic document from a future version of the program.
6. Fixed bugs related to the hang of the modeler under certain conditions.
7. A system for synthesizing active filters for Qucs is being developed (expected in version 0.0.19)
8. The development of interfacing with other open-source engines for modeling electronic circuits is underway (
