Custom Chips: Test any digital circuit in your browser with Wokwi 

I had a lot of fun making this and, to me, the custom chips feature takes simulation with Wokwi to the next level because there's almost nothing I do that doesn't involve some kind of sensor, storage or specialized processing working alongside the MCU. And I've only just begun looking into how to use this as a way to inject input and otherwise do testing... pretty cool :)

This guy is gifted. He types while talking. Writing code is as natural as talking for him. I want to build a triple half H bridge and write a driver for a sensorless brushless motor but I only have a dual trace scope. It would be great if I could start my design on a simulator first.

I discovered Wokwi a day or two ago and honestly I've been having a blast just messing around with things. Even for someone like myself who's just a tinkerer, the ability to make a custom chip is a *great* way to learn how I2C and SPI work. Heck, considering the documentation's out there, making a whole 6502 would be hypothetically doable. this function reminds me of Logisim, if anyone here remembers that old software.

I am speechless! I was already a great fan of Wokwi (since the videos where you emulated the espressif ISA), but with this "custom chips" functionality the sky is the limit. Great job!

this guy is unreal! are you kidding me ?? how do you brain this fast !!!! Thank you for the intro and to Wokwi. hope to be able to do what you do (maybe in 10 years lol).

thanks a lot! this is so cool. just what i wanted. im a developer and dont have the tools (and dont want to buy them) but i wanted to play with some electronics. specifically the z80. the custom chip is crazy amazing. awesome video and explanation, super clear voice and speech, even a non-native like me could understand. thanks also for not having music images or noises that distracts. also great edition to cut the excess. thanks!

awesome breakdown. i just found wokwi. i was wondering how this process looked, and here's a video :) thanks a lot.

Very nice, thanks for doing this video. This certainly opens the door for lots of creativity!

Wow this is great! So many possibilities!

Спасибі за ще один хороший огляд! Єдине: маленька одруківка в назві відео: ''Я там Катя?", хоча це надало цікавої ''фарби'' назві цього фільму.

Wokwi, dream come true 🎉

simple great tutorial! keep doing it...

Best Video have viewed this year. Perfectly explained while shows the possibilities using Wokwi. Well Done! Thank you for making this video.

AMAZING...Love it....thanks

Oh man, how didn't I know about this 3 years ago...

This is just brilliant

wow! neat video and sim tool

When you type, and same time talking, while casual, looking to camera, you look like you play symphony with piano 😁😉 i envy your skills soooo much🤗

man ! u r genius

i like SimulIDE, free one and pretty sophisticated

thanks a lot!

as an ad-on, for paying customers, add on a chip supplier data base and market portal; new (with chip place of origin) and used (ditto, as so many come from China). Your logical area of development then would be into hardware for setting and soldering on chips and board chip removal for the used market. Further hardware would be automated chip testers. Grinding up chip is so anti-productive from at the very least the energy perspective. I see this tool as a good start to get the electronic cottage industry going.

Wow. This needs to be posted to reddit arduino

Brilliant!

thanks bro

Thank you, very nice demo! Is there any chance to see some of demonstrated components (4511) among standard wokwi components ? (Maybe something similar like a small otp memory (e.g. MCM5304) allowing a quick insertion of the data pattern like a kind of universal decoder alternative/replacement).

Good job. 👍🏼🇧🇷

I think relying on an API that mimics the terminology and structure of VHDL or Verilog would be very convenient.

The host mentions "Keycad" in the video. Guess I'll eventually need this in my learning journey, where can I get this tool? Search result sends me to a mechanical engineering tool, I'm so confused.

It sounds very cool, but seems to rely heavily on things that don't relate to real-world device, i.e. how you code the chip. So if the project works in the Wokwi, it doesn't guarantee it will work in metal, and if it doesn't work in Wokwi, it might still for in metal. Also, is there a public repository, so that everyone doesn't need to reinvent a 7-segment driver IC?

We cookin up a 4004 in this one 🔥🔥😂😂

M.2 (or NVMe) SSDs are storage devices, not RAM (Random Access Memory). RAM is a type of volatile memory that is used by your computer to store and quickly retrieve data that is actively being used or processed. It's much faster than traditional storage devices, including M.2 SSDs. Using an M.2 SSD as RAM is not practical due to the fundamental differences in how RAM and storage devices work: Speed: RAM is significantly faster than even the fastest storage devices. RAM is designed for ultra-fast access to data, while storage devices like M.2 SSDs are optimized for high-capacity storage and sequential read/write operations. Volatility: RAM is volatile memory, meaning it loses its data when the power is turned off. It's optimized for quick read and write operations but is not suitable for long-term storage. SSDs, on the other hand, are non-volatile and designed to store data persistently. If you need more RAM for your computer, you typically have to physically install additional RAM modules on the motherboard. The use of storage devices as virtual RAM (via pagefile or swap space) is a common practice, but it's not a substitute for physical RAM because the speed of storage is orders of magnitude slower than RAM. If your computer is struggling with memory-intensive tasks and you've already maxed out the RAM, you might want to consider upgrading your RAM or optimizing your software usage rather than attempting to use an M.2 SSD as virtual RAM. 10% is mine please

Hello, Thanks for the great video, I have stupid question can I build any custom chip as powerful as esp32 in WOKWI? Thank you again.

Thanks for doing this video. Do you have a plan for emulating a monochrome P10 led matrix with hub12 interface?

How do you set the VCC and GND pins with attributes

Hmmm...malloc() to a local variable within a function, the pointer not even returned? And then used in other functions? Looking inside the actual project code, it seems that the malloc() of the state struct is assumed to be the FIRST allocation in the user memory. So...don't do a malloc PRIOR to allocating the state struct or all the other functions will look at the wrong data. I wonder, would it be that more expensive to have a cleaner API?

I am trying to make an analog read circuit for custom circuit. Is it possible to do it? The value(0-255 or 1024) should be printed in the chip console.

hello, great project, is there plans for golang for chip definition and tinygo for firmware?

Wow, this is so cool. Also, how the heck does this guy speaking and coding with his eyes close? 😄😄😄

wokwi is wonderful， but web simulation is a little slow， why there is not an exe file running in windows or linux

I wonder if i can get the Z80 working in it :D

Such level of coding ease and understanding of doing thing reveals he is definitely a developer of this service. Good job! But how is the quality of these custom chips being checked? How can one be sure it functions properly and fully corresponds to real equivalent of the chip? Otherwise it's just a useless toy.

Like the guy with Swiss accent said, Hac and features like led has very low current to glow... Or reverse polarity burns the ICs or at least not let them work...

Absolute Sir ! Your Great! Can you give the Way How to SIMULATORE the cip PT2314 , SI4703, and LCD ILI9486 no touch pls Sir i Need ti realizze my project

Is this open source, where is the documentation to install amd run the server, can you change the default running port, can you make a default blanck project? Thank you if these all have answers.

I can't code this fast, let alone talk while coding. May I could if I grow my hair long, too. LOL.

Interesting and Great Info ( Your Hair is Attractive).

hello man greetings do you have any ideas regarding ade7758 chips?

No capacitors ?? Why have they not included this component ?

Just found out about Wokwi, and I am going down a rabbit hole here, trying to find out if I can run golang on this, since golang can now compile to WASM

I want to work with Mq135 should I use custom chip for it.....?? Name mq135 for Air Quality Monitoring

Have I just found electronics Jesus? Electro Jesus?

Can you add valves or is it stricly digital?

i have a feeling that guy has done some C++ before...

Lol, highly advances 4511 breakout board, have fun with simulation of mixed signal stuff. 4511 is a few lines in VHDL/ghdl sim.

its been a year

Odeio esse cara! Ele fala como se fosse facil como andar de bicicleta! rsrsrsrsrs

I assume you can’t simulate a PIC micro, doesn’t surprise me, no one simulates PIC chips.

Val kilmer

He lost me at designing his own chip! LOL

Your face is redundant while on working area.

The moment you started typing code like a mad woman/man? you lost everybody's interest in term of simplicity about Wowki.

Thank you very much. ❤❤❤ THANKS GOD AND THE VIRGIN MARY AND SAINT JOSEPH. ❤❤❤❤❤ Happy thanksgiving to Wokwi and your family and Everyone. ❤ 25.11.2023 ❤ 7h18 ❤ 14.12.2023

Woke simulator for hippies is not for former Soviet Union Советская Армия technicus-elektronstik.

thanks a lot!
