We are proud to announce the birth of the Free Silicon Foundation (!

We organize a conference in Paris, March 14-16 2019, to promote:

1. Free and Open Source (FOS) CAD tools for designing circuits
2. the sharing of hardware designs
3. common standards
4. the freedom of users in the context of technology

Program and submissions:

I'm heading to to the "EU Open Source Policy Summit" ( Registrations for online participation are still open. Please attend or drop me a note if you have a particular wish to be represented.

Right after I'll be around ( and .

The EU proposal we submitted in October last year HAS BEEN ACCEPTED!!

It is a "Coordination and Support Action" for open-source chip development.

The full text of the submitted version can be downloaded at:

The project begins today.

During the "Grant Agreement" preparation some significant modifications were requested. In particular, F-Si is no longer the coordinator, but EDI in Latvia.

The Free Silicon Conference 2022 is over and most videos are available on:

Watch the keynote speech by Frank Karlitschek founder of
"Why Open Hardware and Open Software are necessary for our future":

@Karlitschek thanks again for your contribution!

The next Free Silicon Conference will be held in Paris on July 7,8,9 2022 (COVID permitting) and we need your help to reach out to new people!

We want to bring together followers of the free/libre chip idea, people who love sharing experience, code and tools.

Is there any name/entity you would like to see or to meet? If so, please drop us a note.

If your idea is not listed yet on you should definitely let us know!

We have submitted a proposal for a European call entitled "Coordination and Support Action (CSA) for Open Source Hardware for ultra-low-power, secure microprocessors":

Our proposal can be downloaded at:

We feel that sufficiently new ideas have been generated for justifying the publication. This will further increase the of the selection process.

If you have any comments please leave them below.

The affair shows that complex systems have backdoors that can be turned against everyone by malicious interests. This could affect hardware too.

The general discussion should nevertheless not drift away from the question about the (il-)legitimacy of such companies/government

An article in German entitled "Consequences of the US boycott: China builds up its own EDA industry "

By-the-way, the problem with EDA access touches Europe as well, and Free and Open Source is an alternative too.

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

" 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 ."

"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 (

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 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:
