Falstad Circuit (2024)

1. Circuit Simulator Applet

  • Circuit JS

  • This is an electronic circuit simulator.  When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage.  The gray color indicates ground.  A red color indicates negative voltage.  The moving yellow dots indicate current.

  • Per Mark’s suggestion, I decided to create a Resources category. For my first post, I will post an obvious one. The falstad circuit simulator is one of the best ways to get an intuitive feel for electronics using simulation. They visualize current flow throughout the circuits, which is one of the best ways to start learning about electronics. Though we focused on LTspice for CE v1 and v2, we will be using Falstad in v3 of CE. http://www.falstad.com/circuit/ Of note is the “Circuits” menu a...

7. Falstad's Circuijs now has relays ! | Details - Hackaday.io

  • I was trying to simulate my incrementer's new carry logic and noticed a new feature in http://www.falstad.com/circuit/circuitjs.html : configurable relays !

    You can edit the coil's inductance and resistance, the contact's on and off resistances, the coil's on current and the number of contacts. Still missing is the off current so this is not yet ready to simulate hysteresis. I sent a bug/feature request ;-)

    This page already has some links to relay simulators but circuitjs stands on its own and does many things, moderately well but well enough for most cases. I used it a lot to simulate many types of circuits and now even more !

    What else do you think is still missing from circuitjs ?

    (And for those who might wonder, here is the new circuit for the carry logic, using coils in series instead of parallel as in a previous attempt, so now the current is constant for each slice of 4 bits)

FAQs

How to show waveform in Falstad? ›

If you want to see the waveform, current consumption, power or voltage, the scope tool can be used. This can be used on most of the components excluding some such as Triodes. To see a components waveform in the scope, you can right click the component and select "View in Scope".

How to use circuit simulator applet? ›

If you move the mouse over any component of the circuit, you will see a short description of that component and its current state in the lower right corner of the window. To modify a component, move the mouse over it, click the right mouse button (or control-click if you have a Mac) and select “Edit”.

How to do circuit simulation? ›

The process of simulating a circuit begins with the “modeling” of each element from the circuit in terms of basic building blocks such as current and voltage sources, resistors, capacitors, and inductors. The parameters for each element in the model may be time-varying or time-invariant.

How do I enable waveform? ›

When you want to dump waveforms during your simulation, the following compile-time and run-time switches need to be enabled. At compile-time, add the +acc+b switch to give support to waveform dumping. At run-time, add the -waves switch with the waveform file name.

How do you trigger a waveform? ›

Depending on the trigger settings, the waveform playback can occur once or continuously. A trigger signal comprises both positive and negative signal transitions (states), which are also called high and low periods. You can configure the signal generator to trigger on either state of the trigger signal.

Is Falstad a good circuit simulator? ›

If you limit yourself to certain components like resistors, capacitors, switches, and inductors (bearing in mind the limitation mentioned above), the Falstad simulator will do a very nice job of simulating things. It's also pretty good for simulating simple logic circuits, though its library of chips is rather limited.

How do you scope in Falstad? ›

Hover over the lower-left resistor, right-click and choose View in Scope. The voltage vs. time of that resistor is now plotted in the scope view at the bottom of the window. Click on the switches to see the voltage across this resistor changes as the switch settings are changed.

Is LT Spice free? ›

LTspice® is a powerful, fast, and free SPICE simulator software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits.

Is CircuitLab free? ›

Master the analysis and design of electronic systems with CircuitLab's free, interactive, online electronics textbook.

Is EasyEDA software free? ›

EasyEDA is free and permits commercial usage, with no disparity in features for individuals or businesses.

Which software is used in circuit simulation? ›

By far the most popular simulation tool for students and circuit designers in industry is PSpice. PSpice is an evolution of the Simulation Program with Integrated Circuit Emphasis which originated at Berkeley in the 1970s.

How do I add text in Falstad? ›

Once you have selected "add text" click somewhere on the screen and drag. It is just like adding a component.

How do you show waveforms in ModelSim? ›

wlf through ModelSim-Intel FPGA Edition, ModelSim, or QuestaSim, perform the following steps:
  1. Type vsim at the command line. ...
  2. Click File > Datasets. ...
  3. Click Open and select your . ...
  4. Click Done.
  5. In the Object browser, select the signals that you want to observe.
  6. Click Add > Wave, and then click Selected Signals.
