When designing my recent project with PCBWay www.pcbway.com/, I had to run ERC (Electrical Rules Check) and DRC (Design Rules Check) in the schematic and routing. In this video, I go through 3 common errors for ERC and DRC each and how to solve them with KiCad. I end with a discussion on using Test-Driven Development philosophy in ERC/DRC. Is that better? Let's discuss!

Very interesting look into these tools. I use them to keep my own distractions in check, too often have I swapped TX and RX pins accidentally only to discover the issue after the PCB layout is designed or worse, when the PCB prototypes come from the manufacturer. I do have to say though, the quality of the ERC/DRC output is directly linked to the quality of the footprint. If a pin is wrongly identified in the footprint the ERC won't know about it, so it's good to keep that in check, especially when you're the one making the footprints.
I liked your methodology of doing the checks at specific stages and then do version control with them. Where did you learn about these design process techniques, like TDD? It seems like a major flaw in my engineering degree because I never really learned these things.
"Where did you learn about these design process techniques, like TDD?"
I had spent some good years in between in web development that made me comfortable with programming, version control, documentation, and concepts like TDD, CI/CD and agile development.
Coming from the school of engineering, I did not learn these concepts initially and they certainly petrified me 😅
@@sayanee Yes, my background is very academic (physics eng.), so when I got to work in the industry it was a whole different way of doing work. Unfortunately none of the companies I worked for exposed those troubleshooting techniques to me, it was usually someone else's job to do the testing, so I guess I have to learn it by doing it myself haha. Thanks for the reply! Keep up the good work!
Thank you for such a clear and well spoken tutorial. It was refreshing to have someone cover all of this information with clarity and in an articulate manner. Sooo helpful! Thanks 🙏 🙏
Absolutely helpful to me. Thank you!
Thank you again for another great video. Looking forward to seeing a video about a KiCad CI pipeline ;)
thanks for posting this
Thank you ever so much for covering all the errors I'm coming across as a newbie starting with Kicad.
You're so clear and to the point. Excellent video.
I'm not sure why Kicad continues, even in Version 6.0, this hopeless "power flag" system. It really does need replacing with something more intuitive, and/or, easier to find in the libraries.
you are great! i was using altium designer before and want to try kicad 7
thank you so much for this Video!
You saved me a lot of time and frustration.
Thank you for such a Great video
you have fixed my mistake, thank youuuuuuuuuuuuuuu
Ok , that’s a couple more dialogs I wasn’t aware of , Thanks 😃
I'm always discovering hidden features I never knew 😅
Ami ai first akjon bengali lady pcb designer (kicad special my favorite)🤩🤩🤩 k dehklam khub khub khusi holam + amr problem o solve hoa geche , thank you mam.
Very nice to meet you too! Glad it helped you :)
Thank you
Voce e maravilhosa ! otimo video, me ajudou muito !
Your videos are really informative and helpful. Thanks 🙏🏻 for the contents. I am an electronic hobbyists trying to learn how pcbs are designed. Really liking your tips on schematic designs. Do you have a discord server? I think that will be great platform for discussion rather than TH-cam comments.
I don't have any discord server at the moment 😅 I usually go to the respective forums like KiCad or GitHub and post my questions there.
@@sayanee having something like discord will be great to have conversations with your subscribers/viewers where everyone can exchange their ideas. Please consider having one, that will be awesome 🙂
Hi ms, i have problem conflict pin ms, conector usb output gnd with ams117(3.3v) output power ms. I have change like your but still error. And now i have change electrical type conector usb gnd from power output to passive, and work ms. I will ask you, if change lile that in future will get problem when pcb was done printed ms??
This has absolutely nothing to do with the video’s thematic but I’m curious about your MacBook. Let me explain why. I’ve finally started entering the apple universe and I still lack an apple computer. My windows Lenovo was cunningly nicked by my dear wife in order to work remotely, and my budget is a little bit on the low side. The things we do for love… My question then is, how far back is it advisable to purchase an iMac or MacBook in order to be able to run these applications like kicad , vc or arduino ide and getting a couple of years of support from apple regarding updates. I’m not into video editing, the goal here is to be able to make some projects and learn along the way. I would be quite happy with that. I’m not interested at this point in having to learn several side things like knowing how to setup a Linux distro and make it work with every single little thing. Just have something I turn on and it works so I can focus on my goals. Thanks in advance.
Well, in this case, you will be happy to know that my MacBook is very old 😅
It's a MacBook Pro (Retina, 13-inch, Early 2015), processor 2.9 GHz Dual-Core Intel Core i5, and memory 16 GB.
And I use it for coding, firmware development, KiCad, video, and photo editing. So you have lots of choices and hopefully a much more modern machine. I have also duat booted it with Linux and Windows in the past.
"Just have something I turn on and it works so I can focus on my goals." Yep, I have gone past the stage of trying to build everything from scratch and having something that just works, so MacBook is great for that in my opinion. 🤪
@@sayanee As a bit of a joke, back in the day parents would give their kids the old PC's when they were no longer useful for work, so the kids could have something to play with. These days, it's the other way around. When the computers are no longer viable for gaming, they go to the parents so that they can work.
Your hardware is far more advanced than what I'm using, an old HP Compaq 6005 Pro SFF with AMD Phenom II X3 B75 and 8 Gb of RAM. Threw in a 240Gb SSD drive, and it's running Linux mint like a charm. What I did invest in was in a 29" ultrawide screen. I am not at all regretful, it has the huge advantage of allowing me to have two documents open side by side in full scale, and it makes creating documents while consulting others so much easier. I hadn't acquired this PC at the time I asked you about your Mac, and my idea was to get one for myself. But here lies the problem, when you cannot update the software any more, perfectly good hardware becomes useless, or so I thought. Now, seeing that you installed Linux in it, it could become a possibility once more. Thank you for your reply, it was very enlightening.
