In my electronics journey I've seen people mention spice and I've never known what they were talking about. How are you giving away all this information for free? This is absolutely the highest quality electronics education. Thank you so much
And here's a link for the list of shortcuts: www.analog.com/media/en/simulation-models/spice-models/LTspiceShortcutsForMacOSX.pdf?modelType=spice-models
Thank you. Retired old goat .. ehr ... pro dipping my toes into simulation. Just a nice little getting started tute, just what I needed. And no duffa duffa music - brilliant!
Helpful. I did some math on making a custom power supply card for an old device. I was going to assemble a prototype on a breadboard but I think I'll try LTspice out to verify instead. TY :)
Good idea! The idea of "measure twice, cut once" has always applied to my math skills when it comes to engineering and design. Let us know how it goes!
I don't get the oscilloscope when I click run. LTSpice shows a text file with the values for each component instead? Output: --- Operating Point --- V(n002): 3.33333 voltage V(n001): 5 voltage I(R1): -0.0333333 device_current I(R3): -0.0333333 device_current I(V1): -0.0333333 device_current
That is odd - all the pertinent information is there (arguably much easier to read than the oscilloscope) but I can't figure out how to do that with my version of LTSpice. I'm running LTspice XVII for OS X, what version are you using? Looking at screenshots of LTSpice on Windows, it kinda looks like they've dumbed it down for Mac users by removing a lot of the options.
@@CircuitBread Thanks, I think I removed .op and manually entered 1s into the transient tab of the run menu. The oscilloscope showed up once I ran a transient test and I could probe different points of the circuit. I'm using XVII for Windows 10 btw.
I had the same issue (new installation on Windows 10). Your advice of entering "1s" for Stop Time in the Transient tab enabled the scope window worked. Thanks for sharing that
it is full of bugs: simulate 5 diodes of different models where each model has its own band-gap voltage (Eg parameter). All 5 IV curves overlap: model card cannot differentiate based on Eg.
Hi Alza! We're making a series on basic circuits and plan on releasing more advanced LTSpice tutorials as the circuits themselves become more complicated, which, eventually could be turned into its own independent short series, I guess.
when i simulated myself i got 5v(the first thing) and then something like 3.5,i think one is the voltage that enters the circuit and the other is the output
I'm new to LTSpice and got a question. When I execute dc operating point analysis (.op), i don't want a time dependent graph but rather values of currents/voltages written directly. And this is what i see on the tutorials of the windows version. Is it also possible in mac?
I noticed you have a three-button mouse on your Mac. I find that if I try instead use control-click on my trackpad to do a right click, this works when adding a component, but fails when using the pointing finger cursor to edit a component.
Thanks Brian, good insight. I don't know if it's because I'm old or what, but I hate using trackpads for any work like this and always have an external mouse. I'm not really familiar with how to use any CAD or spice program without a real mouse and typically a full keyboard.
@@CircuitBread I realized after using the tool more what the reason is. Control-Click and Right-Click are interpreted as different and distinct commands. So LTSpice overrides the Mac system preferences reserves Control-Click for a few situations.
I downloaded LTspiceXVII and it seems to have many differences to what you are using to the point where I couldn't work out how you measured voltages across components, so it was not as useful as it could have been.
Thanks Ajay! We're working through the basic circuits tutorials right now. The plan is to create more complicated LTSpice tutorials as we come across more complicated circuits!
It seems like every ee cad tool's UI is updated every week so this tutorial is not matching what I see in May 2021. I get a one shot analysis, not a real time meter style
I've been meaning to do another version of this with a Windows machine as well, as it seems the greater differences are due to Mac/Windows differences. LTSpice doesn't look like it's updated it's GUI as often as other EE CAD tools, to be frank... 😬
It's strange how unintuitive it is, isn't it? The easiest way is to get into the Delete mode (either by pressing F5 or right-clicking, click Edit, then Delete) and then your cursor will delete anything you'd like. Good luck!
I had to play around with it a bit to get them to work on my other Mac and I don't remember what I did. Now I have one of the newer Macbooks that has that little changing toolbar on the top (I've had it for a year and I still dislike it) but with this one, I just have to hit the "FN" key and then the function keys pop up on that dumb little tool bar thingy.

Just the video I needed as a newbie to LTSpice, thank-you! I've subscribed.
Thanks for the clear explanation AND the tip for entering G for Ground :-)
No problem!

I like to watch a video a day from this channel. Thanks
And getting your comments on our videos always makes my day, thank you!
Thank you. Retired old goat .. ehr ... pro dipping my toes into simulation. Just a nice little getting started tute, just what I needed. And no duffa duffa music - brilliant!
Ha! Glad it helped, have fun!
The Windows version is a lot more 'Busy ' if you know what I mean ! thanks for your tutorial as it does get you up and running...cheers.
It's BETTER, that's exactly what you need to know.

How to glue it together and turn it on - exactly what I was looking for.
Thanks for the video.
PWL is PieceWise Linear.
PieceWise Linear - awesome, thank you!
Great Teacher
I don't get the oscilloscope when I click run. LTSpice shows a text file with the values for each component instead?
Output:
--- Operating Point ---
V(n002): 3.33333 voltage
V(n001): 5 voltage
I(R1): -0.0333333 device_current
I(R3): -0.0333333 device_current

That was good thinking to replace that - thanks for letting us know your solution!
@@CircuitBread Thank you for making these videos!

Pls make more videos about electrical engineering.
Good content indeed🔥
SUPER Helpful. Thank you!
it is full of bugs: simulate 5 diodes of different models where each model has its own band-gap voltage (Eg parameter). All 5 IV curves overlap: model card cannot differentiate based on Eg.
looks like an interesting programme :) is there a download link :)
love it. great intro. Do you plan on making a short series?
Hi Alza! We're making a series on basic circuits and plan on releasing more advanced LTSpice tutorials as the circuits themselves become more complicated, which, eventually could be turned into its own independent short series, I guess.
why isn't voltage 5v at 6:45? when i simulate it by myself i find 5v
when i simulated myself i got 5v(the first thing) and then something like 3.5,i think one is the voltage that enters the circuit and the other is the output
also you have two resistors
so ofc its not the same
Oh thanks
Thanks
I'm new to LTSpice and got a question. When I execute dc operating point analysis (.op), i don't want a time dependent graph but rather values of currents/voltages written directly. And this is what i see on the tutorials of the windows version. Is it also possible in mac?
Found it! Go "View > SPICE Error Log" and you can see values as a list. Thanks to Woolsey Workshop:) Those guys have nice articles.
Excellent intro

Great clarification, thanks for the follow up!
I downloaded LTspiceXVII and it seems to have many differences to what you are using to the point where I couldn't work out how you measured voltages across components, so it was not as useful as it could have been.
That's a bummer to hear - also the differences between the Mac and Windows versions are greater than I would've hoped.
I found the same, Mac v Win and maybe also a later version in my computer. But I still got good value from it.
THANK YOU!
You're welcome, John!
Do you really use that software without the toolbars? Wow. Why?
I think it's a Mac versus Windows thing. I don't see an option to put the toolbar on the top.
I right click and nothing happens
need to right click right on the components,not on the name
Still not sure how to measure total circuit resistance in a circuit using this program. =(
Helpful :)
is it still worth learning ?
Great video...but please do something complicated in lt spice.
Thanks Ajay! We're working through the basic circuits tutorials right now. The plan is to create more complicated LTSpice tutorials as we come across more complicated circuits!
have not dug into it yet, buy can you open and close switches during a simulation?
Hey Robert, yes you can! You just have to set your initial conditions.

why it doesn't even open on my Mac?
SO, how do u go about deleting components you don't want. Like I can't even do that
It's strange how unintuitive it is, isn't it? The easiest way is to get into the Delete mode (either by pressing F5 or right-clicking, click Edit, then Delete) and then your cursor will delete anything you'd like. Good luck!
@@CircuitBreadThanks. I had to sit down for a few hours editing a good chunk of the hot keys.
My version of LTspice seems to be completely different. I can't get anything to work! :-(
Thanks for the feedback Stuart - I'm getting enough feedback that I may make a Windows version of this tutorial.
@@CircuitBread would love a modern tutorial !
hi, the shortcut keys such as F2,F3,etc. are not working in my mac.
I had to play around with it a bit to get them to work on my other Mac and I don't remember what I did. Now I have one of the newer Macbooks that has that little changing toolbar on the top (I've had it for a year and I still dislike it) but with this one, I just have to hit the "FN" key and then the function keys pop up on that dumb little tool bar thingy.
@@CircuitBread yes it already works now with the FN key. Thank you!
👌👌👌
