Next week, Thursday May 18, follow the online session on the future of European open hardware, hosted by the Next Generation Internet (NGI)

Streaming is via BigBlueButton and does not require registration.

The third Free Conference () has been postponed to 2021
because of the coronavirus pandemic.

Watch the teaser for FSiC2021!

" from 2011 to 2019 vulnerable to two new attacks"

"With Collide+Probe, an attacker can monitor a victim’s memory accesses without knowledge of physical addresses or shared memory when time-sharing a logical core. With Load+Reload, we exploit the way predictor to obtain highly-accurate memory-access traces of victims on the same physical ."


Quoting the Washington Post:

* "Crypto’s shift to **electronic** products [..]. Foreign governments clamored for systems that seemed clearly superior to the old clunky mechanical devices but in fact were **easier** for U.S. spies to read."

* "a **circuit-based** system could be made to appear that it was producing endless streams of randomly generated characters, while in reality it would repeat itself at short enough intervals for experts [..] to **crack** the pattern."

"The intelligence coup of the century"

For decades, the read the encrypted communications of allies and adversaries exploiting backdoors in silicon chips.

Free and open-source silicon will allow everybody to audit the full chip design, from netlists down to layout.

Keep up with Free silicon!

The Free Silicon Foundation adopts a different funding model than and promotes independence.

We think that certain sponsorships are problematic not only because of an evident conflict of interest (e.g. vs ), but also because they induce some people and/or organizations like our not to attend , therefore impacting, among others, the plurality of views on topics which can be as delicate as licences (

@aral @xerz

We did not suspect that Google is since 2013 not only **a** sponsor, but **the main** sponsor, of the Free Software Foundation Europe @fsfe : . Thanks for the hint!

This is like if ExxonMobil was financing Greenpeace.

Just like for the SFC @conservancy above, we removed the from the white paper.


We were not aware that @conservancy is financed by Google. Thanks for pointing this out!

The choice of including the Software Freedom Conservancy (SFC) in the paper was inspired by the role of Bradley M. Kuhn in the creation of the Affero GPL (

Since an involvement of Google conflicts with our standards (as stated in our statute, we have removed the SFC from the white paper. Anyhow, they have not provided any feedback to it.

We prepared a white paper for the containing recommendations about as encouraged last November:

Please discuss it or endorse it by replying to this thread.
The paper will be delivered on January 31.

A first draft was shared in December with:

* @aprilorg
* @fsfe
* @fsf
* Aral Balkan @aral
* @waag
* @conservancy

What are the limitations of existing free and open-source (FOS) electronic design automation () tools?

What is it missing to design a chip with 1+ Million gates?

Which will be the first foundry to open a process design kit (PDKs)?

These are some of the questions that will be addressed at the third Free Silicon Conference () which will be held in Zurich on June 4-6 2020.

The third Free Silicon Conference, , will take place in Zurich on June 4-6 2020.

It builds on top of the previous edition (FSiC2019), where 100+ experts and enthusiasts gathered together to discuss how to design free/libre silicon chips.

To get involved visit:

The submission window opens on January 1st and participation is free of charge.

The European Commission is organizing a "Workshop about the future of Open Source Software and Open Source Hardware", Brussels, November 14-15 2019:

Online registration will close on November 6.

Is it possible to simulate transistors using open-source tools only?

How fast are the available solvers?

How hard is it to interface with existing PDKs?

The following talks provide very promising answers:

* ngspice - an open source mixed signal circuit simulator, by Holger Vogt

* Gnu Circuit Analysis Package (GnuCap), by Al Davis

* Converting 45nm transistor netlists to open standards, by Thomas Benz

Which foundries are the most friendly to open-source? Is there an open-source ?

Kholdoun Torki of Circuits-Multi-Projects ( provided a great overview:

"Towards Foundry PDKs on Free CAD Tools"

All the recordings of the Free Silicon Conference are now online:

Day 1 focuses on high-level design. Some of the concepts presented in the first talks can be partially applied to FPGAs as well

Day 2 discusses aspects closer to silicon, such as PDKs, memory generators and layouting

Day 3 presents hands-on tutorials

The full program is available at:

The past Free Silicon Conference was opened with a great talk by Todd Weaver from :

"The Future of Computing and Why You Should Care"

We proudly announce to run our own instance to host the videos of the past Free Silicon Conference 2019:

Is it possible to design a silicon chip using 100% Free and Open Source (FOS) tools?
Can one publish the layout?
Which impact can be expected?

These are few of the questions that thirty-six speakers will address at the second Free Silicon Conference ().

Last chance to attend: reservation deadline is next week (February 21):

Cannot join in Paris? No worries! We are preparing the equipment to record all the sessions.
