Sometimes a bug can happen on a mac when it becomes impossible to add, select any chips or to create any wires, or to create any inputs/outputs.
If this bug happens to you and you don't want to exit and lose all your progress, the solution I've found is to click on one of the existing input/output rectangles (as if you want to rename it), and then everything works fine again.
Sometimes it is also impossible to click on these rectangles on one side. Then usually it is still possible to click on them on the other side. So to be protected from this bug, the first thing you should do when creating a new circuit is to add at least one input and one output to it.
You don't in-game, you have to go into %appdata% to change it. On windows search for run and run %appdata% (with the percents). It should be somewhere in that file area I don't remember where.
I understand, but when showing negative values you make the first of the 4 bits negative allowing 7 to -8, but I was wondering if there were other ways of representing negatives.
Imagine trying to pack 10 pounds of shit into a 5 pound bag. ^_^
Like I said, you can store 16 different values with 4 bits. If you want to add another value, you're gonna have to add another space for it. I thought about some kind of compression scheme, where like you would take two bits, and output the first bit as the first value, and then output a 1 or 0 depending on if the second bit was the same as the first bit, but that turned binary into greycode with no reduction of size.
Fundamentally you cannot compress the most basic structure of digital data. You can only compress higher orders of data where there is some excess 'unused' space created by the data strucutre.
For example, BCD: it's not possible to compress a single BCD digit into smaller than 4 bits, but it wastes 6 values, so something like Chen-Ho can reduce 2 digit BCD from 8 bits to 7 bits, and 3 digit BCD from 12 bits to 10 bits.
Oh how i remeber when pc was 32bit, IS ANNOYING ALL BEING 64Bit, So i gave up & today i use a 64bits pc.
The point internally (ironically this program explains the science behind of this) Your 32-Bits based devices will be obsolete on the year 2038aprox (Because some sort of overflow in the timer will be restart your time, its sounds meh; but look arond of the bug Y2K)
I just downloaded for mac high sierra version, and it is not working. I appreciate your efforts but I would recommend not requesting donations before users experience the software.
He took time out of his day to develop a program to help people learn and is distributing it for free but appreciates a donation. I used this exact program on Mac and it works. Posting comments like this will just make people distribute it for money without a free option.
Signal speed is constant. If you want to change it's speed, make easiest frequency generator by register, NAND-clock and adder. Fastest clock signal you can ever make in this game could be made by NAND-clock(I commented one guy's question about clock below, so I made there all of them I ever used [Sierpinski generator doesn't count, because I made it for fun]).
Thanks for the reply. Clocks are not a problem. I wanted to be able to show i.e. D-latch instability as in the video, with the signal propagating back and forth. Well, maybe in a later version then.
You can't delete projects and chips in game. All of them situated in: C:\Users\user_name\AppData\LocalLow\Sebastian Lague\Digital Logic Sim\SaveData on WindowsOS, and: /home/user_name/.config/unity3d/Sebastian Lague/Digital Logic Sim/SaveData for LinuxOS. They named similar as in game. If you want to edit chip, delete old one and make another one.
P.S. I really tired to answer similar questions about editing and deleting in this game. What's problem to read all comments below before asking your questions?
Yeah, that's true. Sorry, if I answered roughly. But, really, if you look below, every second comment tells about path to the game files, where all projects are situated.
I found that if you create another chip with the same name then exit and reenter the project then it automatically replaces the chip without saving the old one.
[CLOCK-makes clock signals, if input is "1"] [ON-constant "1" output] [GATE-lets inputs signals to output, if POWER input is "1"] [INC-increases binary input by 1] Register was made in dev's second video.
In results, we have 8 outputs, which switches on with different frequencies. Choose any you want.
I meant name of user of computer. For example, i have two users on my computer and both of them have radically different desktops and workplaces. I setted up this game on my main user space, so i need to find this folder on his space.
Inputs and outputs has decimal numbers, if you group them (up to 8 inputs/outputs in group). Also its possible to make them signed, if checkmark is on.

I cant install the game. How do i fix this problem
Anyone know how i can add multiple outputs to a single line like in this example?
every pin can only one conection
yea i figured that out but i came up with a solution to that issu
OR gate ;)
or gate before hand
Use or gates
try removing a gate you cant
yes you can. Select and press backspace
Very cool just made an 8 Bit calculator with a built in clock
Nice :D
How to make a divider?
use repeated subtraction. It’s a little difficult to do it in circuits
PLEASE
add the ability to edit already existing logic gates! It's so frustrating without it!
it is
how?
Wrong comment
how?
maybe it doesn't work or something is wrong but you can't fix it
This...
This is a MUST feature.
yes!
Can i run this program on a x86 system?
yes you can only run it on x86 systems
when will he do another video / update?
How do I make the propagation animation, like he did in the video? Like how the wire slowly fills in the video?
It can't be repeated on this version. He used more updated version of the game.
yes it can, just build an adder like he did and add two registers. Run the output of the alu back into one of the registers.
he said like logisim but the reality logisim more worse
I think, that logisim is more for work. This game made for learning logic basics. But mostly, i agree with you.
Also, he said about logisim just as example. You can find more alternatives.
Can you make a video on youtube about all your circuit you made it?
But why in my opinion this program is better than logisim?
Because logisim is boring to me.
the only reason you might think this is better is because its clean and feels new, logisim is old and outdated
Why Sebastian didn't update!!!!!!!!!!!!!!!!!!!!!!
He has not only this program, so he haven't so much time for this game.
how to edit chips?

how to reset projects
?
You don't in-game, you have to go into %appdata% to change it. On windows search for run and run %appdata% (with the percents). It should be somewhere in that file area I don't remember where.
On a Mac: Go to (open Finder, then press ⌘+⇧+G)
~/Library/Application Support/com.SebastianLague.DigitalLogicSim
All your projects will be in the SaveData folder, so you can delete them manually.
im an idiot, how do we have the new blocks get the in/outs circles?
Add them to the side by clicking. When you save the block they should be there.
I'm still confused, from what I see I just click the side and it pops up that I can add them?
just click the either side of the screen, it shows the dots before placing them.
ok
How do you represent 8(with 4 bits), if the 4th bit is -8 the highest you can go in 7 with 4 bits.
you can represent 16 different values with 4 bits.
I understand, but when showing negative values you make the first of the 4 bits negative allowing 7 to -8, but I was wondering if there were other ways of representing negatives.

I didn't make All things the same on official video
how many updates per second in clock gate
It's about 250 tics per minute. Maybe I miscalculated, bit i tried my best.
I questioned this question to make time in this game!
i made new type of gates i named "d sr latch"
and jk flip flop?
how do i make sr flip flop?
how do i open the app.
extract the zip to somewhere on your desktop open the folder and double click the .exe
Does anyone know how I delete created "chips" and project saves?
I can't understand question: are you asking how to delete or you can suggest another way to do it? If first, chesk this post:

is there a 32 bit version? My pc is 32 bit
Oh how i remeber when pc was 32bit, IS ANNOYING ALL BEING 64Bit, So i gave up & today i use a 64bits pc.
The point internally (ironically this program explains the science behind of this) Your 32-Bits based devices will be obsolete on the year 2038 aprox (Because some sort of overflow in the timer will be restart your time, its sounds meh; but look arond of the bug Y2K)
i was using a 32bit os bc windows 10 is so bad to old machines that my pc cant handle the 64 bit win10 somehow, now i manage to change to linux
yoo is so hard to avoid 32bit if your pc is Phissically incompatible with him :U
if you want to use linux the problem is as well is stuck on your specific pc as 32 bit version
u an download the source code and build it for 32bit i guess
I just downloaded for mac high sierra version, and it is not working. I appreciate your efforts but I would recommend not requesting donations before users experience the software.
Thank you,

who is modder?
i dont understand how to add input or outputs how do u do it
To add itnputs/outputs press left-mouse-button on left/right side of the screen. To group inputs/outputs use + button.
This game is
addictingfunthis is not game , is just sim
also how do i make a decimal display like what was done in the vide

It's five comments below.
how do i delete my custom chips like or gates because i made chips that don't work and i need to ether mod them or delete and create new ones.
https://itch.io/post/3020134
There is the answer (this post is situated 3 comments below yours).
and me
meu amigo, tem como fazer uma versão 32bit por favor
update or mode
Can signal propagation speed be adjusted?
Great project btw.
Signal speed is constant. If you want to change it's speed, make easiest frequency generator by register, NAND-clock and adder. Fastest clock signal you can ever make in this game could be made by NAND-clock(I commented one guy's question about clock below, so I made there all of them I ever used [Sierpinski generator doesn't count, because I made it for fun]).

How do I delete a project? How do I go back to a chip I messed up on to correct it?
You can't delete projects and chips in game. All of them situated in:
C:\Users\user_name\AppData\LocalLow\Sebastian Lague\Digital Logic Sim\SaveData
on WindowsOS, and:
/home/user_name/.config/unity3d/Sebastian Lague/Digital Logic Sim/SaveData
for LinuxOS. They named similar as in game. If you want to edit chip, delete old one and make another one.
P.S. I really tired to answer similar questions about editing and deleting in this game. What's problem to read all comments below before asking your questions?
Perhaps if the main content of the description mentioned then folks would know before even reaching comments.
Yeah, that's true. Sorry, if I answered roughly. But, really, if you look below, every second comment tells about path to the game files, where all projects are situated.
Hey wassup bro,
I found this location for linux..
/home/<username>/.config/unity3d/Sebastian Lague/Digital Logic Sim/SaveData
Good job. Thx.
And on the MacOS in:
~/Library/Application Support/com.SebastianLague.DigitalLogicSim/SaveData
thx i needed this
I found that if you create another chip with the same name then exit and reenter the project then it automatically replaces the chip without saving the old one.
can you make the delay of a clock slower?
Yes, you can.
Just make this scheme.
[CLOCK-makes clock signals, if input is "1"]
[ON-constant "1" output]
[GATE-lets inputs signals to output, if POWER input is "1"]
[INC-increases binary input by 1]
Register was made in dev's second video.
In results, we have 8 outputs, which switches on with different frequencies. Choose any you want.
How do i group up multiple Inputs and outputs to show binary like in the videos?
I just figured it out, press + before placing the input or output, I'm apparently very small brain.
How do I delete my previous projects?
You cannot :(
All projects are situated there (only for WindowsOS):
C:\Users\user_name\AppData\LocalLow\Sebastian Lague\Digital Logic Sim\SaveData
for linux, its
/home/<username>/.config/unity3d/Sebastian Lague/Digital Logic Sim/SaveData
Good job, man. Thx!
what did you mean on user_name
I meant name of user of computer. For example, i have two users on my computer and both of them have radically different desktops and workplaces. I setted up this game on my main user space, so i need to find this folder on his space.
my username on os?
Is there a way to edit an already existing chip
Unfortunately, you cannot
All chip files are situated there (only for WindowsOS):
C:\Users\user_name\AppData\LocalLow\Sebastian Lague\Digital Logic Sim\SaveData
You can delete your chip files, return to game and make another one.
Yo, can someone help me make a XOR gate and some other stuff please, my discord is danny06202#4017
Try this. It works.
thanks
why can't I also put numbers for the output for the 4bit adder
I can't understand your problem. Nothing interferes you to put inputs and outputs (at least on WindowsOS everything works correctly).
Use buttons "+" and "-", if you want to group inputs and outputs (check mark uses for showing binary number signed).
he mean in the official video is if Sebastian made an adder
will in binary number the left had a decimal number
Inputs and outputs has decimal numbers, if you group them (up to 8 inputs/outputs in group). Also its possible to make them signed, if checkmark is on.
Also is it possible to make a clock go slower
It's possible.
Just make this scheme.
[CLOCK-makes clock signals, if input is "1"]
[ON-constant "1" output]
[GATE-lets inputs signals to output, if POWER input is "1"]
[INC-increases binary input by 1]
Register was made in dev's second video.
In results, we have 8 outputs, which switches on with different frequencies. Choose any you want.
Can you help me, please??? https://itch.io/post/2699784
