Kicad Autorouting Made Easy

April 14, 2023 by Al Williams 23 Comments

One of the most laborious tasks in PCB layout is the routing. Autorouting isn’t always perfect, but it is nice to have the option, even if you only use it to get started and then hand-tune the resulting board. Unfortunately, recent versions of Kicad have dropped support for autorouting. You can, however, still use Freerouting and the video from [Mr. T] below shows you how to get started.

There are three ways to get the autorouting support. You can install Java and a plugin, you can isntall using a ZIP file, or you can simply export a Specctra DSN file and use Freerouting as a standalone program. Then you import the output DSN file, and you are done.

DeepPCB Routes Your KiCAD PCBs

December 1, 2019 by Al Williams 36 Comments

Computers can write poetry, even if they can’t necessarily write good poetry. The same can be said of routing PC boards. Computers can do it, but can they do it well? Of course, there are multiple tools each with pluses and minuses. However, a slick web page recently announced deeppcb.ai — a cloud-based AI router — and although details are sparse, there are a few interesting things about the product.

First, it supports KiCAD. You provide a DSN file, and within 24 hours you get a routed SES file. Maybe. You get three or four free boards –apparently each week — after which there is some undisclosed fee. Should you just want to try it out, create an account (which is quick and free — just verify your e-mail and create a password). Then in the “Your Boards” section there are a few examples already worked out.

High-Speed PCB Design Hack Chat With Bil Herd

September 23, 2019 by Dan Maloney No comments

Join us on Wednesday, September 25 at noon Pacific for the High-Speed PCB Design Hack Chat with Bil Herd!

Printed circuits have become so commoditized that we seldom think much about design details. EDA software makes it easy to forget about the subtleties and nuances that make themselves painfully obvious once your design comes back from the fab and doesn’t work quite the way you thought it would.

PCB design only gets more difficult the faster your circuit needs to go, and that’s where a depth of practical design experience can come in handy. Bil Herd, the legendary design engineer who worked on the Commodore C128 and Plus4/264 computers and many designs since then, knows a thing or two in this space, and he’s going to stop by the Hack Chat to talk about it. This is your chance to pick the brain of someone with a wealth of real-world experience in high-speed PCB design. Come along to find out what kind of design mistakes are waiting to make your day miserable, and which ones can be safely ignored. Spoiler alert: square corners probably don’t matter.

Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, September 25 at 12:00 PM Pacific time. If time zones have got you down, we have a handy time zone converter.

Click that speech bubble to the right, and you’ll be taken directly to the Hack Chat group on Hackaday.io. You don’t have to wait until Wednesday; join whenever you want and you can see what the community is talking about. Continue reading “High-Speed PCB Design Hack Chat With Bil Herd” →

EasyEDA Hack Chat With Dillon He

June 17, 2019 by Dan Maloney 7 Comments

Join us Wednesday at 5:00 PM Pacific time for the Easy EDA Hack Chat with Dillon He!

Note the different time than our usual Hack Chat slot! Dillon will be joining us from China.

Since the birth of electronic design automation in the 1980s, the universe of products to choose from has grown tremendously. Features from schematic editing to circuit simulation to PCB design and autorouting can be found in every permutation imaginable, and you’re sure to find something that fits your needs, suits your budget, and works on your platform.

Dillon He started EasyEDA back in 2010 with Eric Cui, and since then the cloud-based EDA tool has become a popular choice. From working across teams to its “run anywhere” capabilities, EasyEDA has become the go-to tool for hundred of thousands of designers. Dillon will drop by the Hack Chat to answer all your questions about EasyEDA — how it started, where it is now, and what we can expect in the future.

Free Routing For GEDA

February 8, 2017 by Al Williams 18 Comments

If you lay out PC boards using software, it is a good bet you have an opinion about autorouters. Some people won’t use a package that can’t automatically route traces. Others won’t accept a machine layout when they can do their own by hand. You can, of course, combine the two, and many designers do.

The open source gEDA PCB package (and pcb-md) have an autorouter, but it is pretty simplistic. [VK5HSE] shows how you can use a few tools to interface with the Java Freerouting application, to get a better result. For example, the original router made square corners, while the Freerouting application will create angles and arcs, if configured properly.
