A truly inspiring talk by @UriShaked @BsidesTLV on democratizing chip making with @tinytapeout.
It's a "WeWork for chips": Instead of paying for a "full office" (chip), independent devs can pay for just a few "rooms" (tiles) + enjoy additional services ( e.g. demo board)

Working on a Z80 replica for @mithro’s https://t.co/mrZyXPFbPk tapeout in a couple of days. 180nm proces and 5 mm^2 die area could be a perfect match for reviving retro chip manufacturing! FOSSi, open source silicon.

🚀 Bringing My Own Silicon to Life

For many years, hardware has been a hobby I've been passionate about. Over that time, I've brought several kewl projects to life- but this one is different.

Over the past few months, I've been slowly learning and working on something that still feels surreal: designing and taping out my own silicon chip through the @tinytapeout program.

My project: a SHA-256 processor- is part of the TTSKY25A Multi-Project Wafer shuttle (launching in 3 days!), built on the Sky130 PDK (SkyWater 130nm technology) and based on the open-source Caravel framework. I designed it from scratch in Verilog, iterated across multiple versions, and optimized it to fit within the ultra-tiny 4×2 tile footprint.

What started as curiosity about how cryptographic cores could be implemented at the transistor level turned into hours of:
🔹 Debugging synthesis and placement with OpenLane
🔹 Experimenting with ROM macros vs. algorithmic constant generation
🔹 Shrinking designs to squeeze performance into just a few thousand gates
🔹 Learning how PDN pitch, macro placement, and even tap cells can make or break a layout

Another kewl part? Early next year, I'll be holding an actual silicon die in my hands that runs code I wrote and logic I designed.

We often take for granted the chips powering our world- phones, servers, AI accelerators... Going through this process firsthand gave me a deeper appreciation for just how much ingenuity and effort goes into every square millimeter of silicon.

I like what Alan Kay once said: "People who are really serious about software should make their own hardware." Well, I think I'm starting to consider myself serious about software 😉

Excited to keep pushing forward with open-source tooling, community knowledge, and the chance to explore hardware design in such a hands-on way.

Huge thanks to @UriShaked , Matt Venn, Pat Deegan, and the @tinytapeout community for helping me out through this process!

💡 If you’re curious about Tiny Tapeout or ASIC design, I'd be happy to share more on my experience - this has been one of the most rewarding learning journeys I've taken.

ASICs are cool.
FPGAs are ❤️.

@alehresmann Yes, only on CrowdSupply.

They're starting to become collectible item :)

@PsychogenicTech @always_ff_rohan @tinytapeout @fishPointer I found a past chat with actual numbers:

running my TT07 mandelbrot set accelerator, which fits into 12 TT tiles, used 8673 LCs (164%).

I tried to use the DSPs, was barely able to fit the LCs (4944), but ran out of DSP units (needed 12, had 8)

Our chip viewer just got an upgrade: now you can see microscope images, GDS, local interconnect and jump straight to project files. Spot something cool? Dive right into the design.

FabricFox: Little FPGA board that's a drop-in replacement for the ASIC on @tinytapeout TT06+ demo boards. It'll be CRAM configured by the RP2 on the DB, so it's uber simple. @fishPointer : does this save me from the culling?

[Uri Shaked @UriShaked]

@PsychogenicTech @always_ff_rohan @tinytapeout @fishPointer "It depends" - IIRC, silife_max from tt05, could barely fit into the ICE40UP5k, yet it was only 6 tiles on TT.

KianV ulinux in space, in full action. That would be nice.
