We are resuming our quarterly meetup for the London open source community, focusing on RISC-V, hosted by the BCS Open Source Specialist Group and the UK Open Source Hardware User Group. These meetings provide an opportunity to share the latest ideas around open source in the RISC-V ecosystem, combined with plenty of time for networking.
This time it will be a virtual meetup, and we’ll be livestreaming using BigBlueButton to provide a rich online experience for participants. As always the talks will be recorded for later upload to YouTube.
For the first time in the history of the semiconductor industry it is possible to design, verify, manufacture Systems-on-Chip (SoC)’s that have been completely developed using an open source process technology, open source IP and open source design automation environment.
In a collaborative effort with Google and SkyWater, efabless’ team has designed and implemented the striVe SoC family using SkyWater’s SKY130 130nm process, efabless’ OpenLANE RTL2GDS no-human-in-the-loop SoC compiler and several key FOSS components including standard cell and IO libraries from SkyWater and OSU, Dual port SRAM created using OpenRAM, PicoRV32 RISC-V CPU and future versions that will include open source eFPGA blocks – all of them are available under the Apache 2.0 license.
Mohamed will present the striVe open source SoC family with its 6 configurations which will be publicly released to the design community as concrete designs currently on their way to manufacturing. Being truly FOSS and foundry-enabled, the striVe SoC family will serve as physical demonstrators and be the seed for countless community-defined and designed SoC’s stretching the limits of innovation and to serve select commercial markets.SHOW LESS
Today, in a FOSSi Dial-Up talk, Tim Ansell of Google announced SkyWater PDK, the first manufacturable, open source process design kit. What differentiates this PDK from previous attempts is the fact that it is manufacturable: with this PDK, you can actually produce chips with the SkyWater foundry in the 130nm node.
That leaves you as chip designer only with one road block: money. Manufacturing chips is expensive – even for more than a decade old nodes like the 130nm node, you need to spend at least a couple thousand dollars.
You know what? Don’t worry – Google and efabless have got you covered! They are providing completely free of cost chip manufacturing runs: one in November this year, and multiple more in 2021. All open source chip designs qualify, no further strings attached!
Want to run Linux on open hardware? This talk will explore Open Source Hardware projects capable of that task, and explore how RISC-V and free software FPGA projects can be leveraged to create libre systems.
Early this year, the world of electronics saw something amazing. The RISC-V, the first Open Source microcontroller was implemented in silicon, and we got an Arduino-derived dev board in the form of the HiFive 1. The HiFive 1 is just a bit shy of mindblowing; it’s a very fast microcontroller that’s right up there with…
We are pleased to announce that OSH Park, the purveyors of perfect purple PCBs, have become sponsors of the FOSSi Foundation’s activities. We are very grateful for their support and would like to recognize this by listing them on our Sponsors page at the Bronze tier.
We are actively looking for sponsors for the Foundation, if you’re interested in learning more about our activities and why we are looking for sponsorship, then please visit our sponsorship page and for more, see our detailed sponsorship proposal document.
Inspired by the success of open source software, the Foundation will help bring about IP and tools of comparable quality to proprietary offerings, and which are developed according to an open source model by a highly collaborative and inclusive community. The FOSSi Foundation will address the issues the field currently faces; fragmentation, legal uncertainty, design quality, and high barriers to entry.
