Simulation in Fritzing

fai · September 8, 2021, 6:42pm

Hello!
Maybe there will a simulator soon. I made a super basic one which has been merged in the Fritzing repository (in its own branch), but it has not been merged in the development branch. If you are able to compile it from source, you can try out. If not, you will have to wait until is released (hopefully in 0.9.9, but I cannot guarantee that). It still needs some work and it is an experimental (beta) feature, but it is functional.

HOWEVER, the simulator is really limited and it will not be able to simulate Arduino and its code. So, it will not be what you need. I have some ideas for being able to simulate Arduino code in the future, but it will probably take years and it is not guaranteed.

If you want to learn more about the features of the current simulator, the documentation is here:

# Simulator Description #

This document describes the features of the implemented simulator in Fritzing. The purpose of the simulator is to teach electronics to beginners. Therefore, the current capabilities are very basics. In the future, we could extend this code to handle advanced analyses, but currently it is not a priority. If you want to help us, please, contact us to discuss collaborations (see the contribute section of this file). 

## Use ##

The simulator is disabled by default. To enable it, go to Edit->Preferences, select the "Beta Features" tab and check the enable simulator checkbox. This option will be saved and you only need to activate the simulator once. Of course, you can still disable at any time in the preferences dialog. 

After the simulator has been enabled, a new button called "Start Simulator" should appear at the bottom bar (next to the "Share" button). In order to use it, build a circuit as usual and add a multimeter to measure something (voltage, current or resistance).  Then, press the "Start Simulator" button and the simulator will be working. Thus, you will observe some changes: (1) the screen of the multimeter will show the result of the simulation, (2) the parts not being simulated are greyed out, and (3) if any device is out of specifications, a smoke appears over it. From now on, every time that you modify the circuit, a new simulation is performed. In order to stop the simulator and remove all the artifacts that adds (smoke, greyed out effects, etc.), click on the small arrow in the "Start Simulator" button and select "Stop Simulatior". Thus, all the items of the simulation disappear (smoke images, text in multimeters and grey out of the non simulated parts).

## Features ##

The current implementation performs a dc analysis (operating point). By default, there is no output of the voltages or currents in the circuit. To be able to measure them, you should use the multimeters of the core bin. There are five multimeters but currently only the dc multimeters work (voltmeter, ammeter and ohmmeter). 

### Currently supported devices ###

Currently, a very limited types of devices are supported:

* Resistors
* Capacitors
