Orange kitty in his ark during this absolute deluge of Skywater tonight in Davis. I have walked around looking for roof leaks - it’s that much water. He still wants to be outside — but he has an electric heating pad so he’s fine. #cats #rain #skywater

As someone who grew up in drought-stricken California, there is something very special about the first significant rain of the year.

I feel compelled to go out and dance in it.

O Z80 está morto! Vida longa ao Z80! - Retrópolis

Semana passada a gente falou um tanto sobre a Zilog largar mão do Z80. A gente também falou algumas coisas erradas, então publicamos uma errata que recomendo a leitura, nem que seja para impressionar os colegas no bate papo no cafezinho da firma. Mas em um ponto do texto, eu disse que alguém entraria em

@LoneLocust We have, exceptionally, had a day entirely free of #SkyWater. (So far, at least.)

It looked mysterious at first and it completely didn’t follow the gate description, but it’s actually really easy to read by just focusing on the pull-down network. From left to right: if C&A | A&B | B&C then we pull the inverter down, thus a majority gate (MAJ3).

The #IEEE conference paper I was working on last year is finally published!

The UC Santa Cruz team did all of the actual silicon design work, while I did the post-silicon bringup, testing, and characterization.

"#SRAM Design with #OpenRAM in #SkyWater 130nm", 2023 IEEE International Symposium on Circuits and Systems (ISCAS)

Also presented at OSDA 2023 https://www.youtube.com/watch?v=Wm8VV4Ba224

SRAM Design with OpenRAM in SkyWater 130nm

OpenRAM is an open-source framework for the development of memories with an initial focus on SRAMs. OpenRAM provides an application interface for netlist, layout, and characterization to create designs using either open-source or commercial verification and simulation tools. The first silicon in SkyWater <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{130}nm$</tex> has been successfully verified which includes a 32-bit 1-kilobyte dual-port SRAM macro. This paper presents the first macro design, test setup, test results, and enhancements on a subsequent tape-out.

#TIL courtesy of #FOSSAsia:

"The SkyWater Open Source PDK on Github is listed as a collaboration between Google and SkyWater Technology Foundry to provide a fully open source PDK and related sources. This so that one can create manufacturable designs at the SkyWater foundry, that target the 130 nm node. Open tools here should mean a far lower cost of entry than is usually the case."

Creating A Custom ASIC With The First Open Source PDK

A process design kit (PDK) is a by now fairly standard part of any transformation of a new chip design into silicon. A PDK describes how a design maps to a foundry’s tools, which itself are d…

@matthewvenn "Efabless want all the submissions to run a top level timing check" So does this mean that anything that's not synchronous logic is out? Clearly async or domino say will not pass any of the timing tool they have. That's a pretty unfortunate restriction. #tinytapeout #asic #skywater #asynclogic #dominologic #digitaldesign #efabless
