You should also make it so the chip making area is a drag around thing so there's unlimited space and we can zoom out. that would allow us to make MUCH bigger and better thing
on your video, the way you made the ALU made it so if you were to subtract 0 from 0 it would say that the answer is 0 but it would also make the carry output true. here's my fixed ALU, which does not have this problem:
To the peeps who made a discord server dedicated to this simulator, can u pls send a server invite that doesnt expire, and btw my discord is 29#1731, hit me up.
this simulator gotten a little annoying i tried 5 times to make a main memory BUT IT STILL DOSENT WORK no matter what i do or how careful i plan they don't work can you please make things work without connecting all the dots up Thank you
i will set up a tutorial on igmur.com (image tutorial) on how basic CPUs work but can you please tell us when or what is going to be in the next update when its small if its a big one you can keep it a surprise if you want but please tell us something.
do you know the game battleship it’s like that but first you need to know about how to do encoders and decoders. first is decoders what that do is take a 2bit and up binary input (without 2s compliment) and put out a single output per section. 0000 input turns on the 0 output 0001 turns on the 1 output and 0010 turns on the 2 output and etc. with a 4 bit input you’ll get 16 outputs total each 16 outputs represent a number through 0-15.
Also you can create 2 output clock if you get one signal before left "not" and after left "note". It would be helpful sometimes. For example i used it in fibonacci sequence calculating, when i needed to rewrite result in another register per tick.
Unfortunately this doesn't seem to be working on the new M1 Macbook Pro. The buttons on the top and the settings under CREATE all disappear when clicked.
Okay, so a few problems. Solid GUI, but come on man why can't you delete anything? Like, you can delete individual instances of a certain gate, but if you put a typo in the name or something there's nothing you can do except restart the whole project or learn to live with it. Speaking of, if you did make a mistake in a project and have to start over, you can't delete the old project. Plus, maybe instead of starting with AND and NOT you could just start with NAND or NOR, since you can make every logic gate out of either of those as a starting point.
all gates (including NAND and NOR gates) can be made with the AND and NOT gates but its much more complicated for no reason if you went the other way meaning starting with the AND gate and the NOT gate makes it both simple and diverse.
How is it complicated? It's no more complicated than making OR from AND and NOT gates. Look, the way I see it is there's two potential goals here, start simple for beginners (in which case it makes sense to also include OR, the other basic gate) or build your way up from nothing (in which case building everything from NAND or NOR would be better).
If there is a feature missing that you like then make it. He made it open source on Github. I cant stand when people put out a project for free and everybody acts all entitled without lifting a finger to help.
He's posting it on itch.io for donations, I assume that means he eventually intends to make money on it. I'm not gonna do his work for him and contribute to a project for someone else to make money on. I contribute to Open Source projects that aren't monetized. Besides, it's in alpha, I'm giving my feedback, so apparently all feedback is entitlement now? Plus, how is it entitlement to want a feature as basic as deletion? Look you can get off your high-horse and stop being a dick to people requesting features in a product that is in alpha specifically to get feedback.
Donations doesn't mean monetization, that's the entire damn purpose of donating; it's if you really like what someone's done and want to support them. I'm sure that at least some of your "not monetized" open source projects you've contributed to have a donation system.
I downloaded it and accidentally put on the highest graphics. It crashed and now when i open it it instantly crashes. I have reinstalled it five times and restarted my computer. Can someone please help. On mac btw
Does this work on Windows 32-bit? I am using a 32-bit Windows tablet. When I try to open an application that says "Digital Logic Sim", it says that this is not compatible for my computer. It is in the Digital Logic Sim (windows) folder. I extracted the folder. I have 2.14 GB free.
you don't need that many registers all you need a is main memory and 2 accumulators for the processing, a 2nd larger main memory for Control unit and memory data registers, also known as MDR or multiple like Cache, Cache is THE main memory that is between the CPU and RAM what it dose is that it take HUGE chunks of memory at once (mostly 4 eight bit registers at once) then send it to the CPUs memory and control unit. it also sends data back to ram or to main bus. (about the memory input from ram to cache is much bigger than that IRL)
Why "that many registers"? I only have two. They are in the SWAPR4. (Btw, all the 4s refer to word size.)
I do not use a main memory, but two stacks (+1 for consts) and one code memory (in CMD4) instead. If you only have 4 bit as the instruction word, you don't want to waste a lot on immediates for offsets, nor with only 16 instructions on two word instructions. I don't understand what you wanted to imply regarding caches, surely in this simulator and on this level of CPU memory access latency plays not a role (compare with CPU in "the early days" like the 6502).
Yes, it's not a "classic" architecture, but I thing in might be Turing complete (assuming the stacks and program RAM would be infinite ;) ). I went for this arch because I wanted to test the individual chips well before putting them together (editing is not possible atm).
Dude, what you're saying makes/made no sense, you can't really show him anything, since it's his custom arch. His architecture is great for what can be done in this game.
actually you can press the + key while hovering over the input/output bar to add them. you can also select the word size by pressing it again until you have the desired size.
But i m having a problem downloading it. once I download the software and extract the zipped files and then open it it shows a pop-up message that this is not compatible with my computer.
could you please tell me how to solve that problem?

You took the words right out of my mouth. This change would be helpful anyway
did he die?
i am worried
I sure hope not.
He created a chess game. Dont worry, he is ok.
if he ok why he didn't make update
What is the discord server invite? make one so it lasts forever
Could you make it so multiple wires can connect into one spot
Just use an or gate
i have but it just takes up space.
The smaller the name and the less input/outputs you use the smaller the chip
how can you get smaller than or...
is it possible to delete projects? i just dont like a ton clogging up the menu
C:\Users\user_name\AppData\LocalLow\Sebastian Lague\Digital Logic Sim\SaveData to find your projects and chips. Good luck.
Where is this located on Linux?
I use only Windows OS, so i dont know where it located on Linux.
I use Linux (and Windows, but that's beside the point) and I don't know ether, so I will explore and tell you if I find it.
Good luck. I hope you will find it.
i use only windows 10 OS

This is amazing, I've been looking for something like this to help me learn. Also love the videos.
Thank you!

hey, can i join the discord server?
i am Frostie#8802 on discord
Can i join too Kureshik#5677
Pls add me too 83.rs#3983
Can you send a new link
how do I use other gates then and/not?
if you know then thank you so much :) - Me
I mean the store gates and stuff
That's what that means.
U give it a clock a stor signal an done
bad grammar = 7 yro kid
bruh English is my second language
Watch the official video for learning basics or read instructions in game.
***k you
I cant really understand what you really want. Almost all basics showed on official YT channel of this game. To infinity and beyond)
u sus
Add inputs and outputs, wire AND and NOT gates to the inputs and outputs, then press the create button at the top left.
How do I make the displays
U can create ur own. He posted the source code on github.
I looked through the seemingly relevant .cs files but I couldn't find how to actually make them. How would I go about this?
in the newer versions just press the + and - buttons on your keyboard
to group these inputs
yes :)
Hey I know Im a bit late to the party, but can you please add me to this discord server? Wojtex#2648

Please make a permanent one
but i need part 3 please
but have a problem if man need to make 1kb is = 1024 bytes
are bytes = 8 bit how to make?
How to slow down the signal speed in simulation, as in his video?
for anyone interested in deleting logic gates I made a tutorial.
I don't get it.
Much faster to find all projects in "C:\Users\user_name\AppData\LocalLow\Sebastian Lague\Digital Logic Sim\SaveData" folder. But your way is creative.
Thanks. I really needed this info
What does 'signed' mean when you group inputs and outputs together?
It means if the display is using two's complement or not. I think
do %AppData% in your search bar then go to Appdata at the top then go to LocalLow and then Sebastian Lague
how do i make ram?
He will make that in the next video I think. There is also a crash course series that shows you how on youtube.
if you what I can tell you the basics of it
on your video, the way you made the ALU made it so if you were to subtract 0 from 0 it would say that the answer is 0 but it would also make the carry output true. here's my fixed ALU, which does not have this problem:

There needs to be a way to edit chips easily. The only way I've found is to create a chip with the exact same name and close and reopen the project
Could you make something like that about networking/data transformation/data representation or something similar?
btw awesome content!
why is it using so much gpu? im on a laptop core i5-8250u , UHD 620 . its like 90% gpu usage.
i tried making a Carry look ahead adder and somehow i made it slower than a ripple carry adder
time to go back to the drawing board
I made a button!!!
Why so complicated? Input IS button... I cant understand, but you made funny thing.
Also, "and" operator does this thing much faster.

A simple clock
you can turn on and off
ya well the clock here docent has a 50/50 tempo it has a random speed from slow to high tempo constantly
Another clock which seems to be steadier is this:
ok ill just clock it by hand sense its more reliable till he adds a clock to the simulator
Also you can create 2 output clock if you get one signal before left "not" and after left "note". It would be helpful sometimes. For example i used it in fibonacci sequence calculating, when i needed to rewrite result in another register per tick.
the ability to zoom out or scroll would be nice

I built a small 4-bit CPU that is really hard to program, because it heavily relies on swapping registers. It's basically a river-crossing puzzle. :)
If you want to try it out here's the Github link: https://github.com/gschwaer/Swappy/blob/main/Readme.md

I’ll show you the setup because you only need 2 accumaltors and 4 registers nothing special

How'd you add those displays to it?
It was video editing, they werent actually there.
actually you can press the + key while hovering over the input/output bar to add them. you can also select the word size by pressing it again until you have the desired size.
hi
I have watched your videos are really great.
but now I want to download this software.
But i m having a problem downloading it. once I download the software and extract the zipped files and then open it it shows a pop-up message that this is not compatible with my computer.
could you please tell me how to solve that problem?
Are you sure you downloaded the correct version for your operation sistem?
If you downloaded the correct version, I dont know whats happening, try to talk with Sebastian.
oh yeah you are right thank you for helping me😊.
thank you very much :)
what pc r u on
has anyone managed to mod this to make the icons smaller or something along those lines?
More than three input "and" operators are useless.
how to download this??????????????????????????
Click on the big red "Download now" button. You will get the source files, bc this is itch.io.
You can then unpack the .zip.
