#falstad #circuit #simulation
We will explore the main features of the Falstad circuit simulator which is completely free and web-based. We can create a circuit with many basic components, run a simulation and even add scopes to query the voltage and current. There's also a handy import-export function.

Use the menu "Circuits -> Blank Circuit" instead of deleting all components.

Nice! I totally overlooked at menu item :) Thanks.

Very interesting explanation, clear and to the point. I’m going to binge watch the rest of your videos

Thanks for this video. Are there any simulators that also have CPUs (ie 6502) and\or other common chips?

Kindly suggest for online practical experiment drafting n simulation both for electrical engineering tools.

I really admire Falstad's circuit simulator for observation and learning, but for real-life circuit simulation I would rather use the professional ones.

@sayanee 3 жыл бұрын

Agree with you :) I use it to simulate a very small part of large circuits for understanding how it works too!

Is it possible to add any part number , I mean you find in the library any part number?

@DamonMedekMusic Жыл бұрын

One thing about Falstad is it has vacuum tubes. A lot of simulators don't have them and this app gives me more opportunities to build tube amplifiers. If anyone has a better option let me know.

Thank you i had failed to add a scope on falstad, can you also make a video to show how to install in on windows because i downloaded it but failed to install it.

Hi , I have a doubt in Falstad Simulator . Can i discuss it ?

@_-martin-_ 4 жыл бұрын

I'm surprised you didn't try nor mention Kicad for simulating your circuits. Kicad uses the open source Spice circuit simulator ngspice as backend. While it takes some time to set it up it is very powerful because you can reuse your production Kicad circuit without changing the schematic, except of course adding the ngspice models and attributes to all components.

@sayanee 4 жыл бұрын

I did :) But I felt Spice with KiCad is also better for an example with analog circuits with amplifiers, etc showing the varying frequencies. Also, it's a little challenging to find specific spice models other than the common components found in the PSpice symbol library. Could you reuse the circuit in entirety though? I still had to create another project to abstract out that part of the schematic in KiCad to simulate it in spice. KiCad + spice definitely deserves a separate video by itself which I'm surely gonna need one day :)

@_-martin-_ 4 жыл бұрын

@@sayanee Yes, you can simulate entire circuits and not use any of the simulator Kicad pspice components but instead you have to fill out the necessary fields for all your regular components according to ngspice syntax / naming rules but Kicad helps you with that. For example if you place a normal resistor R_Small with a value instead of a pspice resistor and then hit "Edit Spice model" button, then Kicad will automatically fill in the missing ngspice parameters. The same is true for other basic components. For other advanced components you will need to add the specific spice model file. It's fun when you get everything set up and it works :) Ngspice has a short tutorial online on how to use kicad + ngspice. It is also true that it can be hard to find a specific spice model but that is kind of true for all simulator tools. Oh, and make sure your Kicad is configured to be compatible with PSpice models, this is also explained in the ngspice kicad tutorial.

I’m a amateur in circuit simulation and anywhere we can find circuits prepared by others online? So that we can test and learn their stuff in Falstad simulator

@sayanee 3 жыл бұрын

Under the top menu "Circuits" there are 100s of examples of circuits like transistors, active filters, power converters, etc, that you can already try within the Falstad simulator: www.falstad.com/circuit/

And i am running pauls simulator on my phone (i donhav a lapotp :,| ) and i needed 1 HUUUGGEEE help: how do i import custom components in this simulator? I have been banging my head on this for a long time with no results, do you know how to do this? I mean i have heard of spice netlists n stuff but its confusing (im a first year electronics student) Btw really nice video, please be more regular and keep posting videos :D
