CSE 230 - LogiSim ALU Tutorial

A tutorial on Using LogiSim to design an Arithmetic and Logic Unit

"First I'm gonna show you some basic gates"... proceeds to show the AND gate...
"Now, we're going to make an ALU" aaaand that went 0-100 real quick

Thanks very much for this tutorial a Student at LYIT at Donegal in Ireland in the Field of Applied Computing so this lesson is very helpful to me.

Excellent tutorial! I have seen a lot of videos explaining how to make a 1-bit adder. This is the first video that explains step by step how to make an entire 8-bit ALU, besides it is also a great tutorial on how to start using Logisim. Congratulations, great work!

You're the best logic design teacher I've come across!

Thanks so much! I am a robotics student at UAT and we don't go over it enough in class so this really helps!! :D

Great tutorial!! So well explained! I should be doing homework right now, but this is definitely more fun!

They're for using the ALU to do comparisons - we setup the alu to do a subtraction, then if a and b inputs are equal, the zero flag goes high, and we can use it to trigger a branch. The negative flag is for a "less than" style comparison, in the same way.

literally saved me the night before my 3bit ALU project was due

Amazing video. This really helped me out with a project I had for class. You did a great job walking me through the process. Thanks!

[shadabshaikh]

Just can't thank u more sir.... U just made my life easy

[drbsr]

I got it built and working just fine.
Thanks

Amazing Video, Very Easy Explanation
Thank You From Bangladesh

[danyang]

It's really useful and so necessary for me !Thanks!

This brought me back memories from Devry in the 1980's.

[leifcnp]

Cool, thanks for the intro to logisim!

[kwakukwabia]

Pls what is the significance of the less and set in the ALU?

[manologrhacker]

Nice tutorial. Well explained and easy to follow, I enjoyed.

Hi Ryan. This video helped me to complete a class exercise. The pace, steps and language makes it very easy to follow.. Please, do you have other videos that teach how to add multiplication, division and overflow detection? I want to extend what I learnt from this video as I understand it very well. All the videos out there are either too fast, the language not clear (mostly Indian English, even though very good English but with heavy accent). Can you help, please?

[phddgrd]

awesome, I haven't tried this software ! it seems so practical... thanks... I'm really into digital design right now !

[phononify]

Great -- very nicely explained. Thanks a lot for sharing. Great would be the check on overflow in status with XOR of bit 7 and 6 carrier bit -- Can that software be attached to other programs helping in a hardware layout, as well ?
