What is a Flip-Flop? How are they used in FPGAs?

NEW! Buy my book, the best FPGA book for beginners: nandland.com/book-getting-sta...
Learn about the most important component inside of an FPGA: The D Flip-Flop. Another word for the Flip-Flop is a Register. The reason for this is that it "registers" the input data to the output data on every rising clock edge. Flip-Flops along with Look-Up Tables are used to do the majority of your processing inside your FPGA.
They are critical to understand, so watch this video and unlock the magic of your FPGA!

Now its been 7 years u upload the video. I m doing masters in power electronic and control . Starting i don't know about FPGA. Even my teacher teach be about FPGA. I didn't understand what he said. But U are genius, and i understand what is FPGA . I watch your first video. This this is my 4th video. I m gonna watch your all video. Thanks again .... keep it up.. sir ..

[@ProblahDefied]

More videos!!! These are great. It's like FPGA for dummies.

[@mikail5682]

We did these basics in cs courses, but you fill the gaps in my knowledge very nicely. Those bits of intuition you give make it a lot easier to digest

[@splitpersonalty]

You explained this the same way a college buddy would. You're really good at this.

[@xinxingwang7902]

Good job dude, nice explained and easy to follow. Very interesting to me since I am new to FPGA. Looking forward to your next video!

[@MontanaPreston]

Thank you SO much! I have been learning fpga's and verilog for a long time now at CU Denver and am going to watch your whole series bc I just seem to be struggling so much. You are so much more helpful than my professor and I really want to learn!

[@codesurge6838]

Your tutorials has been great! You provide layman explanation on niche technical terms, it is newbie friendly! Thanks for your effort.

[@GalinaMalakhova]

I love your videos man. I'm a new FPGA designer (and a mechE, so totally don't know electrical stuff) and this is really helping me to grasp the basics!

[@abelashenafi6291]

Thank you!!! for all of your videos. I mean for all of them. I'm Glad i subscribed and thank you "youtube" for providing the platform for seeing a one in a billion tutorial like this. Thanks man I really mean it.

[@nickasher7105]

Thank you for making these videos, they are awesome and the way you explain things are awesome.

[@thetenderloins6564]

That was an amazing elucidation of what a flip flop is....simple and crisp.

[@flain283]

Watched this for the second time, 6 months after the first, but now i have an FPGA dev board. light-bulb moment such a simple thing that as a traditional software programmer i never had to really worry about but this video really helps my understanding as i work on my FPGA project.

[@shirleyachara3809]

The flip flop and rising edge of the clock was so well explained, thanks 🙏

[@PLAIDSHORTS1]

This video is literally GOLD.. ty so much!!!

[@tote4162292]

Should have paid more attention in class but this feels just like a personal explanation from my professor, so thank you so much!! I feel confident about going to class tomorrow.

[@sonasucnad]

These videos are great. I was able to get a really clear understanding of the flip flop after this video.

[@renepromesse7410]

I've been struggling to understand the concept of flip-flop, but now all I can say is thank you.

[@loucostello3111]

Russell. Your video tutorials are the best. I'm ordering a Go Board.

[@Dougie-]

Easy to follow, good explanations. Subscribed. Please more videos :)

Your talking way is very comfortable to me. Update more videos. I like FPGA.

[@killer2point057]

Great info! Thank you

[@Diego-jd2md]

Great video , really good explanation !

[@biancasandu789]

Oh thank you for making this video. It was a pain to find something understandable on my 0 level in electronics. Like the other comments say, please, do more videos. We like your videos a lot :)

[@tgroh007]

Thanks Russel, very well explained.

[@vilaparthyvenkatkamal5175]

Please make much more videos sir, you’re a great teacher . Please do more videos on these type of contents

[@huanlinxberkeley]

Very good explanation. Still relevant today!

[@chathurikadilhani1951]

Ur teaching pattern is quite interesting.. And also speaking style is very pleasant. Well done thank you 🙂💐

[@forhadahmed4643]

[@sunweaveryt]

Amazing video, this is a much better explanation on D Flip-Flops than my professor gave me. Too bad you couldn't be teaching my digital logic class, because I am sure I would actually learn and enjoy the course.

[@Ed-et5gj]

Great work, keep it up!

[@misiayogi2225]

Thanks for your videos, they're great! I am a little worried about how much ink is getting on your shirt, though.

[@thuydang3668]

I confuse how to save date with D when D changing with clock in H state.

[@STEPHENMOIRANGTHEM]

nice .easy to understand

[@jonathandriller2028]

All tha brain storage to learn about all the different flip -flops... sigh - thx Nand great video !

[@joshualove5450]

I have not many time to learn, but I will try understand it. I love electronics :-)

[@mdrezaulkarim47]

clear explanation

[@abdeljalilgzili8662]

thank for your videos they are really helpful .. just i want to say that i use NE555 like a clock

[@drewjohnston9541]

Best video I've ever watched

First time ever I see this type of content and you make it pretty understandable! Please keep making this videos!

[@lei2443]

perfect video thx bro

[@petercheung63]

thanks for the video

[@arthur.passos]

Very good :)

[@edwardbrito8802]

Dude you’re awesome

[@GajuGatera]

super helpful! thank you!

[@viswanathanramakrishnan7613]

Superb information. Will you guide to use flip flop's in making a model train signalling system involving only 2 leds (red and green) per flip flop cascaded so that each flip flop triggers the next one so that green becomes red once the train passes the sensor say magnetic reed switch on the track.

[@NewYorkeez]

Big thanks.

[@amsu7445]

great, thank you

[@DungNguyen-jx4lr]

You are goodlooking :))

[@quantasalman]

Just great

[@erggish]

Thanks for the videos. My main concern is that, although I do get what is happening, I can't make the connection to an actual application that would need this method. So, why would retarding a signal by 1 circle be of use? Would it mean by appending several D-Flip Flops that share the same clock, I can keep in "memory" the data (for N flip flops I could keep the signal for N clock ticks)? Would that be how to create a "MEMORY" functionality in a calculator for example? (not sure if we keep the data or the output of the flop actually).

[@SameBasicRiff]

one way to think of it too, is the "gears" or clock are like tidal waves, coming in and out, with the polar harmony generating the "life" of the circuit. (this helps if your familiar with the concept that the early earth had a moon closer to it causing 100 mile tides, potentially creating life, just like the "life" of the circuit is created by this back and forth, on and off, clock motion. but anyways....... lol)

[@enverkaancabuk73]

Q2 is logic low because of propogation delay at second rising edge.Q does not change at the same time as the clock. It has a small delay each time.
