CFP Introduction

This devroom covers topics mostly related to hardware design (FPGA and VLSI/ASIC).

Libre-SOC is a major project in the open-hardware/free-software space, and will be sharing progress made so far in areas of efficient SVP64 assembler, formal verification, and general Power ISA development (proposed advanced biginteger instructions, etc.)

Libre/Open VLSI, very excitingly, has begun to take off, recently. NLnet sponsors several VLSI-related projects (Cell Libraries, HDL, VLSI tools), Efabless and Skywater bring 90nm, 130nm, 180nm MPWs to the masses.

Please distribute widely to interested parties: anything related to VLSI and Libre/Open Tape-outs and Silicon development is welcome.

We are looking for any libre or open source topic relating to hardware design, including but not limited to:

  • Chip Design (including nanoscale 3D printing)
  • VLSI and FPGA Hardware Design
  • Libre/Open Processors in FPGA and/or ASIC
  • ISA design and usage

This year we welcome talks that are either:

  • 10 min (lightning talk, short introduction of project/topic)
  • 25 min + 5 min Q&A (normal slot)
  • 40 min + 10 min Q&A (extraordinary slot for a topic that needs a deeper explanation)

What is FOSDEM?

FOSDEM is a free event for software developers to meet, share ideas and collaborate.

Every year, thousands of developers of free and open source software from all over the world gather at the event in Brussels.

FOSDEM 2024 will take place on Saturday 3 and Sunday 4 February 2024. It will be an in-person event at the ULB Solbosch Campus, Brussels, Belgium, Europe. If you are unable to attend in-person you can watch any live stream from the main tracks and developer rooms.

Desirable topics:

This devroom welcomes anything related to making an ASIC, or designing one, or using FPGAs, or developing an FPGA Board, or developing tools and techniques that make VLSI ASIC design easier: we'd love to hear from you. Here's a list of topics:

  • Open Hardware projects
  • ISA and Architecture design
    • Simplified Vector extensions
  • VLSI ASIC Design and Manufacture
    • Libre/Open DIY Foundries (nanoscale 3D printing)
    • Libre/Open VLSI tools and toolflow
    • Libre/Open VLSI Cell Libraries
    • VLSI Simulation and Verification
  • VLSI Tools in use or in development
    • Silicon-proven (QFlow, coriolis2, OpenLANE)
    • Under development (LibreEDA, other)
    • Advances in Algorithmics in Place and Route and Layout
  • FPGAs
    • Libre/Open FPGA designs
    • FPGA toolchains and Reverse-Engineering
    • FPGA workflow
  • VLSI RTL and HDL
    • Advanced and innovative alternative HDL tools
    • Formal Correctness Proofs
    • Testing methodologies
    • Hardware Trust (and how to break it)
  • Software Engineering as applied to Hardware
    • Continuous Integration for VLSI
    • Automated tool development (RTL to GDS-II)
    • Automated testing

(thank you to the Open Hardware and CAD/CAM devroom for this snippet)

The talks will be recorded and live-streamed during FOSDEM2024. The recordings will be published under the same licence as all FOSDEM content (CC-BY). Only presentations will be recorded, not informal discussions and whatever happens during breaks between presentations.

We require affirmative consent to this license. Please include the following statement in your submission notes:

If my presentation is accepted for FOSDEM, I hereby agree to license
all recordings, slides, and other associated materials under the

Once you've completed the required sections, submit and we'll get back to you soon!

Things to be aware of

Important Dates

  • December 1st: submission deadline
    • FAQ - is the submission deadline final?
      • Yes. The new submission system is stricter, and thus the, 1st of December is the final date.
  • ASAP: announcement selected talks (15th Dec or earlier)
  • February 3rd: FOSDEM! (with live Q&A during recorded talks)
