Wow what a year! In this video I look back over 2024 and share some of my highlights and the goals I met and failed.
Then I’ll share my ambitions and predictions for 2025!

I'm going to start a regular weekly stream about #opensource silicon. Topics will include design, verification, #fpga, openlane, formal, #tinytapeout, #ASIC bringup, chip validation.
If you're interested, please let me know what days / times work for you:

We now have some limited edition chips mounted in epoxy resin! Each chip is numbered and comes with a GDS render and details of the designs it contains.
Own some open source #ASIC history and support me in my ongoing efforts to lower the barrier to entry into this exciting and important field.

I just booted uLinux on #TinyTapeout 6!
Very easy to use flashing tool by Uri made it easy to test Hirosh's SoC!
Also big thanks to @mike & @mole99 for the PMOD we're using with designs that need external memory.

An alternative to packaging chips is to do 'chip on board', where you glue the die down and then wire bond it to the PCB.
We just tried this with one of my Zero to ASIC course ASICs, and it worked!

I struggled with the cost of hardware development for years, and when someone donated me my first oscilloscope it was a big deal! Seeing the waveforms really helped me to advance my understanding and the complexity of the projects I could undertake.

Another reason is that it can be expensive, and not just for the physical components. We generally need more of a lab than software developers. Test gear is essential for learning how your circuit is actually behaving, matching simulation to the real world. And it’s usually expensive.

It’s become a cliche, but hardware is hard! One reason why hardware is harder than software is that the time between revisions is often longer. We need to wait for new PCBs, or for components to be delivered. Or for more new PCBs after we realise we got it wrong!

I just did a last minute analog #ASIC design - 600MHz ring oscillator. Let's see how attenuated the output signal is!
Design: https://github.com/mattvenn/tt08-analog-ring-osc
3D viewer: https://gds-viewer.tinytapeout.com/?model=https://mattvenn.github.io/tt08-analog-ring-osc/tinytapeout.gds.gltf
Also, I finally taped out my first ever GDS art!

In my recent keynote at the free silicon conference I spoke about The long tail of semiconductors - Education, Tools and Artisanal ASICs.
I'd love to know your thoughts, watch the video and comment or ask a question!
