#sky130 — Public Fediverse posts

Одна DRC-дека, три техпроцесса и двенадцать неверных гипотез

Мы были уверены, что наш DRC-движок универсален. На SKY130 он совпадал с эталонным KLayout до последнего нарушения: тесты зелёные, расхождения нулевые, поведение стабильное от прогона к прогону. Из этого казалось очевидным, что движок применим к любому техпроцессу. Он же просто исполняет правила из деки и ничего не знает про конкретную фабрику. Мы эту мысль не проверили. Мы в неё поверили. И это разные вещи, как выяснилось.

For those who missed the news, efabless, the company that was doing manufacturing for the #sky130 open-pdk has shut down operation ( https://efabless.com/notice )

Definitely a big blow to the open silicon community 😢

They're finally here 🎉️ My very own chips from the Google-sponsored MPW-8 shuttle!
Open source chip design is real and here to stay.

The entire delivery includes bare dies, QFN packaged parts, daughter card assemblies, and a development board.
Many thanks to Efabless for managing the chip fabrication and delivery!

What's inside it? A simple RISC-V SoC with various peripherals, you can find my submission repository here: https://github.com/mole99/leosoc-sky130

and a couple more of the dies because they look cool

I forgot to upload the pictures I took from my MPW-6 chips sent by efabless
These are the dies

Чипы для всех. Свободный стандарт на производство микросхем

LibrePCB : бесплатный инструмент для разработки печатных плат под Windows, Linux и MacOS Идея свободного железа особенно актуальна сейчас, когда крупные корпорации пытаются ограничить доступ к своей интеллектуальной собственности, а национальные правительства ставят друг другу препоны в доступе к технологиям. Многие хотели бы составить конкуренцию лидерам — TSMC, Samsung и Intel, которые являются фактически монополистами в производстве современных микросхем по техпроцессу 2/5 нм.

Today I submitted my final work report for Google Summer of Code 2023 🥳️

It's been an exciting three months, and I now have a much better understanding of what it means to contribute to an open source project. In the end, not only did I achieve the original goals of the project, but even a bit more.

Read on for more information about the project!

#GSoC #SKY130 #Verilog

Today is a good time to announce that I'm working on a GSoC project this summer! 🎉️

Google Summer of Code is a program from Google that sponsors students to work on open source projects during the summer months.

My project is called "Improving SDF support in Icarus Verilog" and I will explain what it is about in the following posts. But just as a heads up: it has to do with chip design.

#SKY130 #ASIC #OpenSource

And another project ACCEPTED for tapeout! I can't even comprehend how fast this is all happening.

This time I submitted a simple SoC: LeoSoC. https://platform.efabless.com/projects/1797

It contains a LeoRV32 core, 8 kB of Work RAM, another 8 kB of Video RAM and circuitry to output SVGA timings to a monitor.

I didn't really expect the project to be selected, since I submitted it the week before the deadline and the lottery is based on submission date. But it's a welcome surprise for sure 😃️

Waveform Generator ACCEPTED for MPW-7! 🎉

I finally got the news that one of my projects, a digital waveform generator, was accepted into the 7th Google-sponsored shuttle run for SKY130.

I will get the actual chips back in a couple of months and can't wait to test them!

Here is the list of projects on this run, you can find the Waveform Generator under Location E7, Slot 33:

Hi everyone! This is my very first toot :)

I would like to take the opportunity to present one of my latest projects:

A generic waveform generator implemented as an ASIC using the open source SKY130 PDK. With a bit of luck, this will be fabricated in the MPW-7 Shuttle through the Open MPW Program.

Development repository: https://codeberg.org/mole99/waveform-generator
ASIC implementation: https://codeberg.org/mole99/caravel_wfg
