Democratizing Chip Design - Naja

“Open source EDA (Electronic Design Automation) can be a game changer when it comes to building a more resilient and accessible chip ecosystem”, says Christophe Alexandre. Together with Noam Cohen he created Naja, an open source EDA tool. The semiconductor industry is highly complex and globally interconnected, which makes it fragile. Open source can contribute to resiliency in what traditionally has been a closed field. Christophe: “Open source EDA tools make it easier for newcomers to get started by providing solid, accessible foundations that don’t require massive initial investment or deep legacy knowledge, and it can bridge chip design with other fast moving fields like machine learning and AI. It can accelerate the creation of a local semiconductor ecosystem by breaking down the traditional barriers and opening up innovation. So trying to grow a new EDA ecosystem in Europe just by using the old closed and behind the gates model just doesn’t seem realistic anymore. If we want to build something resilient, open source needs to be a core part of the strategy.” Links Naja Naja Github Naja Pyhton Naja documentation NGI Zero projects Naja Naja-DNL Learn more about Naja: Christophe at FOSDEM 25 about Naja Python Other projects and topics mentioned Yosys Coriolis OpenROAD Klayout IHP Open source PDK TinyTapeout

Equitable Internet Access for the Under-served - LibreQoS

LibreQoS greatly improves the quality of experience of internet connections. It was born out of necessity during the COVID pandemic when massively increased internet usage resulted in intermittent package loss. Robert Chacón, CEO of LibreQoS and operator of a small ISP that provides internet to under-served communities, noticed how it affected his customers’ ability to work from home and do online learning. In response, LibreQoS was created to fight bufferbloat and latency issues by prioritizing interactive sessions like video calls over, say, downloading large files. In this episode we speak to Robert, Herbert Wolverson (Chief Product Officer), and Frantisek Borsik (Chief Operating Officer). They talk about how they open sourced LibreQoS in the hopes of helping other small ISPs who bring internet to the under-served, and their surprise at the rapid rise in popularity with deployments in 58 countries. They provide insight in the world of ISPs, and how stable internet connections aren’t just about good gaming experiences but can actually save lives. In loving memory of Dave Täht Sadly, Dave Täht passed away days after the recording of this episode. Dave was Chief Science Officer at LibreQoS and made fundamental contributions to FQ-CoDel, CAKE, and LibreQoS to improve the internet for everyone. He worked to make real-time communication available everywhere and insisted his code be free and open source so it would truly benefit everyone. He is remembered by many for who he was and the lives he touched with his work on his memorial page.

Uncovering the hidden patterns of the consumer electronics industry - DeviceCode

“The consumer electronics industry works differently than people actually think”, says Armijn Hemel creator of DeviceCode. Behind the different brands and casings is often the same hardware, created by a single Original Design Manufacturer. But the disclosure of security vulnerabilities is mostly focused on single devices. So when a CVE is published for device A from vendor X it conceals that the security flaw may also exist in a similar device of a different vendor. DeviceCode collects structured technical information about consumer devices to reveal these hidden patterns of the industry in order to improve security. Demystifying the electronics industry can also be a step toward increasing the local production of electronics. Reasons to opt for local manufacturing are the vulnerability of global supply chains, environmental impact, worker rights, software security and preventing backdoors. A better understanding of the industry could inspire a bottom up approach to a more diversified electronics industry.
