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.
@@jimmyraconteur Maybe so but he 'still' has the ability to type and talk while looking at the camera. An average person can't do that. The guy is intelligent. You can't take that from him. Unfortunately for me Wokwi doesn't simulate the Parallax Propeller micro controller so I have to stick with breadboarding.

@@Wokwi I suggest my university students Wokwi so they can test their MCU projects at home without the need to have the real devices with them.

Hello Sam! It's true, I've been doing this a good while now, but I'll gladly admit that a smidgen of editing is involved, hah.

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).
Thanks! Yeah, a PROM would be a good use case for the Custom Chips API. We hope that the API would make it possible for users to create their own parts, based on their unique needs. There are several examples of projects using custom chips along with other parts - check out the links at the bottom of the getting started page in Wokwi Chips API documentation.
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?
I'm getting the same feeling about this. It does appear to be an exercise in writing code, with extra steps. If I have to build the thing at my workbench, to confirm that it works, and when it does, or does not, do what I expect, I will still have the (n="did I get that code right?") variable. And that dang variable can be multiple equations. But, the possibility of having the opportunity to play around with hundreds of pieces of hardware, that I can't afford to buy, is a very satisfying dream… So, I'm going over to play around and see how it feels at my fingertips, because the concept is amazingly attractive. I could see myself paying for a much more sophisticated simulator, if the software end of it had earned the trust of the community. Or, better yet, WOKWi finds its sea-legs, and I get a little more confidant with software. Maybe we can grow together. It would be a tool that I would be using the heck out of, if I knew I could certainly trust the output, or if I absolutely, loved to code. Which I do not.
Is there a way to make voltage level converter? I mean one on transistors. We would have lv1, lv2, vcc3v3, gnd, lv3, lv4, hv4, hv3, gnd, vcc5v hv2, hv1. I think I know how to do it to make it work one way (using example code for inverter) but how to make it work both ways?
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.
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?
Thanks for sharing your thoughts about the API! Actually, the API doesn't assume the state struct is the first allocation of in the user memory. Behind the scenes, Custom Chips use WebAssembly. Wokwi recreates the WebAssembly VM whenever you restart the simulation, starting from a clean state. Therefore, there's no need to free the chip state memory - custom chips are only created when the simulation starts, and everything is destroyed as soon as you stop the simulation. I hope this makes sense!
No specific plans for this part at the moment, but it should be possible to simulate using a custom chip (look at the Framebuffer API in the custom chips docs). Implementing brightness by detecting PWM can be a bit tricky and resource intensive for large matrices.
@@wailrimouche1171 That makes sense. There's a limited support for Verilog, e.g. wokwi.com/projects/371755521090136065 VHDL is not likely to happen any time soon. Also, the C-based chips usually simulate faster than Verilog, so for most use cases, C is probably a better choice.
👍 in theory - yes, in practice that would take months work and there'll be some limitations (performance will probably not be great, custom chips do not support internet connectivity at the moment, etc). What's your use case?
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...
Thanks! Not plans at the moment, but chips are compiled as Web Assembly, so in theory it should be possible to create chips with golang. As for firmware - check out Wokwi for VS Code, where you can load any binary firmware, so you can compile a firmware in TinyGo and load it into the simulator.
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.
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
Depending on how you want to use it, just a simple switch may be enough to simulate it (if you only use the digital input), or a potentiometer (if you only use the analog input). Otherwise, you can also create a custom chip to simulate both at the same time.
@@realryder2626I think this is great for what it's for, I'd say you're better off leaving the analog side of the circuit to spice and the like, rather than mix the analog and digital (it's good practice to keep them physically isolated in the real world anyway). If you're using valves as logic devices you can model the digital logic sepperate to the analog circuit modeling, which honestly makes it a lot easier to work through than treating it as one giant analog monstrosity haha.
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.
So all software-based state machines are just yet another useless toy because they're not implemented by etching oxide layers on silicon? Ouch, I guess we need to throw out all computers then. What a bummer that there are no such things as unit- and integration-tests...
Thanks! That's a good question and one I've considered as well. The fact is, unless you had some formal spec or other model to check against, I'm not sure how to best address this. The second video ("Building a custom I2C chip for Wokwi simulation", ruclips.net/video/BS_uTqz3zik/видео.html ), is a full walk-through of a real world chip and the approach I took was to dive into the datasheet and then check my understanding with an actual physical chip. Don't know how I could do much better in circumstances like that, but if you have any ideas I'm game to try them out.
@@PsychogenicTechnologies Yeah, that's it. "Test + real device" section of your video should be performed for a model of every single chip that will be published for users (ideally manufacturer should be involved in this process). Don't get me wrong, your tools is awesome but as I sad I can't really trust the simulation until it's components were tested in the real world. I hope they will. Thanks for your work and happy prototyping ;)
@@putyavka Yes, I hear you, and agree--and, wow, if we could get manufacturers involved that would really be the best (they all have some way of precisely defining and, I assume, modelling the IC behaviour)... but some want an NDA just to see a blasted datasheet, so good luck on that! For wokwi, I think it's really a question of the old "fast, good, cheap: choose 2" tradeoffs... Personally, I think it'd be awesome to get contributions from everyone, and have it self-correct (a bit) a la wikipedia and other crowd-sourced materials. Would that guarantee reliability? Definitely not, but it's a nice set of trade-offs: everyone gets access, lots can be produced, it's "mostly good"... If it's mission critical to someone, well... they have a mission, so maybe also have the motivation and resources to invest in validating the components they use are being modeled correctly? Maybe a way to share the fact that, yes, *I* validated this and to my knowledge it's good so, if you trust me, then you can reasonably trust module X (a web of trust type thing)... I dunno. Finally, I'm not privy to the internals or all the plans for Wokwi... Uri might have more info on this. In any case, I much appreciate the comments and ideas: these things would be important to address for serious/pro use cases. Thanks!

@Wokwi yeah, I think I'm just trying to find out how it could be done. I will write an article on it if I find a way, but if there is one already, please send 😅
True, we don't simulate PIC - we let users vote on what we should simulate, and no one even proposed PIC as an option 🙂 However, there are some alternatives that can simulate PIC chips, such as PICSimLab and Simulide.

@@putyavka Yes, I hear you, and agree--and, wow, if we could get manufacturers involved that would really be the best (they all have some way of precisely defining and, I assume, modelling the IC behaviour)... but some want an NDA just to see a blasted datasheet, so good luck on that! For wokwi, I think it's really a question of the old "fast, good, cheap: choose 2" tradeoffs...
Personally, I think it'd be awesome to get contributions from everyone, and have it self-correct (a bit) a la wikipedia and other crowd-sourced materials. Would that guarantee reliability? Definitely not, but it's a nice set of trade-offs: everyone gets access, lots can be produced, it's "mostly good"... If it's mission critical to someone, well... they have a mission, so maybe also have the motivation and resources to invest in validating the components they use are being modeled correctly? Maybe a way to share the fact that, yes, *I* validated this and to my knowledge it's good so, if you trust me, then you can reasonably trust module X (a web of trust type thing)... I dunno.
Finally, I'm not privy to the internals or all the plans for Wokwi... Uri might have more info on this. In any case, I much appreciate the comments and ideas: these things would be important to address for serious/pro use cases. Thanks!
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
Shall we open a page for custom chip requests? So people like you can say which chips they are interested in and perhaps other users will create them
@@Wokwi Okay Sir I'll do It ,grazie
Brilliant!
Thanks!
Glad you liked! Have a few more in the pipe, I'll try to keep it shiny and interesting: hoping to get one out not tooo long after the holidays.
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
Interesting! Take a look at TinyGo, it might fit better than the standard golang compiler
@Wokwi yeah, I think I'm just trying to find out how it could be done. I will write an article on it if I find a way, but if there is one already, please send 😅
@@tobeyko no article yet, you'll be the first
Wow, this is so cool. Also, how the heck does this guy speaking and coding with his eyes close? 😄😄😄
🤔
thanks bro
Good job. 👍🏼🇧🇷
Thanks! I hope life is good in Brazil and the weather's better than up here.
Have I just found electronics Jesus? Electro Jesus?
Your own personal electro Jesus. hah, well 'tiz the season :)
Interesting and Great Info ( Your Hair is Attractive).
Glad you enjoyed, I hope it opens up new avenues of experimentation and dev (and... why thank you, Doyle!)
My old friend Jackie Gleason, used to say, " If you got it , why not flaunt it." Hahaha
@@doylepatterson4376 hahawesome! Merry xmas/holidays, see you on the other side :)
Lol, highly advances 4511 breakout board, have fun with simulation of mixed signal stuff.
4511 is a few lines in VHDL/ghdl sim.
I assume you can’t simulate a PIC micro, doesn’t surprise me, no one simulates PIC chips.
True, we don't simulate PIC - we let users vote on what we should simulate, and no one even proposed PIC as an option 🙂
However, there are some alternatives that can simulate PIC chips, such as PICSimLab and Simulide.
i have a feeling that guy has done some C++ before...
I can't code this fast, let alone talk while coding. May I could if I grow my hair long, too. LOL.
its been a year
Odeio esse cara! Ele fala como se fosse facil como andar de bicicleta! rsrsrsrsrs
hah, desculpe por isso. É verdade: não mostro quanto tempo demorou para adquirir conhecimento... ver-me tropeçar seria um vídeo triste (e longo). Experimente e dê um tempinho e ele estará pedalando para você… qual era a expressão: “as melancias vão se ajustar naturalmente ao passeio de carruagem”? Saúde!
The moment you started typing code like a mad woman/man? you lost everybody's interest in term of simplicity about Wowki.
Your face is redundant while on working area.
Val kilmer
He lost me at designing his own chip! LOL
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!
