[@johndelassus3210]

You are my latest KZbin hero. Your LTSPICE lessons are so clear and helpful. Thanks so much for all of the time that you put into this.

[@FesZElectronics]

Thank you for the support! Keep safe!

[@AndrewKiethBoggs]

Your dedication in these videos is amazing. Making my way through them with in depth notes and practicing along.

[@DoctorMangler]

Thanks again for another great video. I really like your use of the help system combined with common pitfalls. Your videos are so helpful, thanks again for the unique and useful content. Your audio is sounding really great these days.

[@DoctorMangler]

LOL It's actually running! Hahahahahah. I do like the longer videos, about 70% of what you were covering is over my head, but not far out of my reach. It's nice to squirrel away tips tricks and pitfalls for future use.

[@FesZElectronics]

I will try to keep all future videos shorter in the 10-15 min range; I just had to try out a long video, to see how it is received.

[@-dazz-]

Mind blowing. I'm speechless. If you see a sudden bump in views for this vid, that's me watching it a million times before I get to understand it well enough, haha.

[@ustjaco]

Great video - really opens the horizon for me. Thanks!

[@FesZElectronics]

Trying to do this task can be very insightful, even if you do not end up with a proper model, you gain a lot of know-how about how a circuit was conceived and how it should work.

[@hosseinpirhady8045]

Beautiful demonstration. Thank you.

[@mohsen8468]

I'm learning so many tips and tricks, Thanks for sharing

Вы настоящий Мастер и большой специалист и энтузиаст. Спасибо за урок!

[@fraiflorin]

Big difference between the NE555 from the LTspice library and the TLC555 from Texas Instruments. Nice that Texas provided the spice model for a better accuracy of the simulation. From now on i will use the TLC555 spice model, for simulation :)

[@FesZElectronics]

Most major manufacturers create very good models for the components they manufacture. TexasInstruments took this one step further and like LT(now Analog Devices) made their own free circuit simulator - the TinaTI. If you work a lot with TI components that might be a better simulator for your tasks.

[@Arcturusing]

extraordinary...perfect explanation....thanks a lot

[@SardarNL]

Very practical, right to the point. Thank you.

[@ahsanalirafaq805]

At 17:51 you used behavioral source for adding delay to make the circuit faster but if we add delay then it means that the capacitors are holding the previous values and won't be charged with new values and adding this much delay will result in loss of data so don't you think this approach to model can create more delays at output and also loss of data.

[@danielwarzecha2007]

Great Video! It seemed like it went really fast at the end and the steps could have a little more detail but I was able to follow what you did by pausing it a few times. Thank you!

[@jipristt]

Really interesting video! Thank you!

[@gustavoarluna]

This is amazing, man! Nice job.

[@FesZElectronics]

Glad you like it! Thanks!

Thanks for your time..

[@jiandingwang3299]

Wow, really hardcore modeling! Thanks a lot!

[@brandonhh4111]

Incredibly Informative!

[@reinaldogonzalezreyes5579]

Hi brother, Your work is amazing and I am very greatfull for your vídeo. I am working in a simulation of analog effect chorus, and I used the compact model from you.. But i note that when I change the frequency, the delay is always the sam1 .. I think that the the problem is in the Intermediate_Point, probably B1 that function needs to be dependt of CP ports frequency, What do you think? , please let me know if i am confuse,, thanks!

Stunning video!

[@zoyaamaan_]

Hatts off to your work 😮. Can you please do a tutorial video on an GFCI IC RV4145... to create model from datasheet.

[@muraterkocevic9743]

Very inspiring. I wish I could do all this at 10% of your speed.

[@FesZElectronics]

Well the magic of video editing does help a lot... Cheers!

[@Catbangin]

Hi is there any way to make those formula into programming language like c/c++?

[@fraskerbasker6120]

Why didn't you use MOS to model it like in the datasheet? Is it harder to get it work with MOS?

[@FesZElectronics]

I remember that at the time I tried this, but it didn't work. You need some sort of special Cmos transistor not just a regular mos-fet. In the end not using a complex component saved some simulation time, since the more complex the components are the slower the simulation will run, especially with so many parts.

[@Ahmad-gn1pd]

Can i make any SPICE model for any ic through datasheet? Is this model give me even the right frequency response?

[@mu8502]

hey friend I have a question and really want to know :in some data shits like ne555 some resistors or capacitors not valued or no model for transistors how can determine them?????

[@FesZElectronics]

Not much can be done in this case unfortunately; the main reason manufacturers don't offer complete info on the components inside of an IC is so that it does not get copied. The main purpose of the schematic inside a datasheet is to give a general functional overview, its not a perfect representation of what's inside.

[@mu8502]

@@FesZElectronics thank you....

[@randomguy7801]

How to add dc motor in simulation?

[@FesZElectronics]

Well it depends on what the purpose of the simulation is. Normally you can simulate it by placing a resistor and an inductor. The resistor will simulate the DC current needed to drive the motor, and the inductor will simulate the inductive component that comes into play when turning the motor on and off.

[@randomguy7801]

@@FesZElectronics Could you include this into your next tutorial?

[@FesZElectronics]

Do you know any other type of components not commonly found in LT that you ran into?

[@randomguy7801]

@@FesZElectronics I think all mechanical components, not sure though. I have just started exploring LTspice and new to electronics. I liked arduino so started learning couple of days back. Is there any way to simulate arduino in LTspice? I am using tinkercad for arduino simulation.

[@FesZElectronics]

Simulating microcontrollers and software I am not sure if it is possible in LTspice, the program was initially designed for power supplies and analogic circuits. But the good news is that there is a different simulator out there that can use to do just that - the Proteus simulator. I know you could simulate the PIC family of controllers also in this program, though I personally never tried it. Whenever I work with uC's I like to test it out in the real world. On a quick google search I found the following, maybe this helps: www.instructables.com/id/How-to-Simulate-Arduino-in-Proteus/

How to model TlP350 for simulation

[@MudBinman]

Could you help to simulate BD34301EKV from datasheet. Thanks in advance.

[@FesZElectronics]

Hello! Unfortunately I was not really able to find a datasheet for this part, but I did find what it is - a high end D/A converter. I am sorry to disappoint but I do not plan on creating more simulation models for components, I created this video to highlight how complex the process can be and some of the steps needed to perform this task. Considering the complexity of this circuit I'm not sure it is possible to create a realistic simulation model in the first place just based on the datasheet - most constructive details are not shown, only the manufacturer knows them... I think the best approach would be waiting on the component manufacturer to provide a proper model.

[@vijayaveluss9098]

Hey great stuff man. what if there is no datasheet but some physics based spice models are available? I am working on FeFET but there's no datasheet or spice models but some IEEE papers are there where they model with physics equations. Can you give me a starter on how to work on that?

[@FesZElectronics]

Well, if you have some sort of mathematical model, you can implement it with behavioral current and voltage sources. These sources allow you to implement various mathematical equations. Is this the sort of thing you are looking for?

[@vijayaveluss9098]

@@FesZElectronics Yeah and I tried to implement with the model but what if there is a feedback for the parameter? like the voltage Vk depends on higher order of it's Vk^n. How can implement that on LT?

[@FesZElectronics]

@@vijayaveluss9098 If you are referring to a syntax issue - x^y can be written as pow(x,y); On the other hand you can't have a recursive formula like x=x+1 implemented in a behavioral voltage source; there needs to be a way to get a clear separation between input and output data - so a feedback mechanism that stabilizes the system can be implemented. Maybe you can share more details, or the exact equation (or source paper) you are trying to implement.
