SkyWater PDK Hack Chat

Join us on Wednesday, September 16 at noon Pacific for the CNC on the SkyWater PDK Hack Chat with Tim “mithro” Ansell, Mohamed Kassem, and Michael Gielda!

We’ve seen incredible strides made in the last decade or so towards democratizing manufacturing. Things that it once took huge, vertically integrated industries with immense factories at their disposal are now commonly done on desktop CNC machines and 3D printers. Open-source software has harnessed the brainpower of millions of developers into tools that rival what industry uses, and oftentimes exceeds them. Using these tools and combining them with things like on-demand PCB production and contract assembly services, and you can easily turn yourself into a legit manufacturer.

This model of pushing manufacturing closer to the Regular Joe and Josephine only goes so far, though. Your designs have pretty much been restricted to chips made by one or the other big manufacturers, which means pretty much anyone else could come up with the same thing. That’s all changing now thanks to SkyWater PDK, the first manufacturable, open-source process-design kit. With the tools in the PDK, anyone can design a chip for the SkyWater foundry’s 130-nm process.  And the best part? It’s free — as in beer. That’s right, you can get an open-source chip built for nothing during chip manufacturing runs that start as early as this November and go through 2021.

We’re sure this news will stir a bunch of questions, so Tim Ansell, a software engineer at Google who goes by the handle “mithro” will drop by the Hack Chat to discuss the particulars. He’ll be joined by Mohamed Kassem, CTO and co-founder of efabless.com, and Michael Gielda, VP of Business Development at Antmicro. Together they’ll field your questions about this exciting development, and they’ll walk us through just what it takes to turn your vision into silicon.

join-hack-chatOur Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, September 16 at 12:00 PM Pacific time. If time zones baffle you as much as us, 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.

Your Own Open Source ASIC: SkyWater-PDK Plans First 130 Nm Wafer In 2020

You might have caught Maya Posch’s article about the first open-source ASIC tools from Google and SkyWater Technology. It envisions increased access to make custom chips — Application Specific Integrated Circuits — designed using open-source tools, and made real through existing chip fabrication facilities. My first thought? How much does it cost to tape out? That is, how do I take the design on my screen and get actual parts in my hands? I asked Google’s Tim Ansel to explain some more about the project’s goals and how I was going to get my parts.

The goals are pretty straightforward. Tim and his collaborators would like to see hardware open up in the same way software has. The model where teams of people build on each other’s work either in direct collaboration or indirectly has led to many very powerful pieces of software. Tim’s had some success getting people interested in FPGA development and helped produce open tools for doing so. Custom ASICs are the next logical step.
