LTspice tutorial - Stepping sets of parameters

[@andresyesidmorenovilla7888]

You are so underrated! I was actually wondering if something like this existed but didn't find much. Thank's so much, all that I know about ltspice I owe to you

[@unlokia]

I think you’re my new favourite electronics KZbinr, because your voice and attitude is so professional and unique. God bless you sir.

One detail worthy mentioning. This docs is inside menu -> help -> help topics, or simply press F1. Then, LTspice XVII -> LTspice(R) -> Dot Commands. This Dot Commands section maybe the most important as I would say, every user has to know how to find this.

Using the voltages as direct readouts for the index variables in the first sim is a nice teaching technique. I'll have to keep that one in my back pocket. Thanks for introducing it to us!

[@seinfan9]

Always appreciate new videos with this tool.

[@mayankgupta460]

Great Video, I am currently learning ltspice and your videos have been a great help

[@yaghiyahbrenner8902]

very good video. such a useful feature man simulation is such a time saver when the tool used is understood.

[@rjordans]

Nice one! Another advantage of 'scripting' these circuit variants is that it avoids problems in copy/paste actions where you accidentally missed a change in one of your simulations. Makes things much more reliable and reproducible.

[@FesZElectronics]

To be honest, if I just want to change component values, this method is ok; but the copy/paste method can be far more useful when changing interconnections or adding different components.

Great work, as-usual!

[@VikasVJois]

Thank you for showing this technique in LTspice. It would be great to see an explanation of the "measure" statements in LTspice. I have a hard time understanding their syntax. In recent versions, there is a GUI implemented to write them but that does not give the entire flexibility and power of the measure statements.

Shouldn't be the .step param n 1 2 3 instead of 1 3 1 at 4:20?

[@ahmedzangana5251]

Huge thanks

[@MegaCadr]

Analog should hire you :)

Great video!

Thank you so much.

Hi FesZ Electronics: What is the purpose of Pgood connexion ?. Datasheet shows typical application without Pgood.

[@FesZElectronics]

In general Pgood, PG, or "power good" is an open drain output that stays high only if the power supply is within ~5% of the nominal voltage (exact % differs from IC to IC). The common use case is to link this pin to a microcontrollers reset so that the uC is allowed to function only after the voltage stabilizes. This is to prevent unexpected behaviors during low voltage supply.

[@aitorsierra]

@@FesZElectronics Ok and in your simulation R5 could be removed and will work without problems.

[@FesZElectronics]

Of course. I didn't really bother to remove unwanted components from the schematic, I just took the default test fixture that LT provides.

[@MJ-vt1kp]

Hey FresZ, Do you have a doctoral title? If not any known university should give it to you ;-)

[@ohmslaw6856]

Alot going on haha big headache lol
