The FireSim and Chipyard user and developer community has experienced rapid growth, with significant cross-institution user and developer collaborations. This full-day workshop at ASPLOS 2023 aims to bring together these communities to help drive the future direction of this ecosystem and spawn new collaborations.

This workshop will feature talks from academic and industrial users of FireSim and Chipyard, across areas like computer architecture, systems, programming languages, and VLSI research/development. We hope that the presentations in this workshop will inspire lively discussion of FireSim/Chipyard governance, feature roadmaps, outreach activities, host platform specifications, and more.

The workshop will have a hybrid format; see the In-person Attendees and Remote Attendees sections below. Remote attendance will take place via YouTube livestream and a Slack for Q&A. See below for links.


FireSim in High-Profile Action—FETT: DARPA’s First Ever Bug Bounty Program
Joe Kiniry, Principal Scientist, Galois

Joe Kiniry
Bio: Dr. Kiniry is a Principal Scientist at Galois and the Research Lead of several programs: High-assurance Secure Hardware/Firmware Design and Verification, Rigorous Systems Engineering (High-assurance Model-Based Systems and Software Engineering with Digital Twins), Trustworthy and Verifiable Elections, High-assurance Cryptography, and Audits-for-Good. Dr. Kiniry is also the Principled CEO and Chief Scientist of Free & Fair, a Galois spin-out focusing on high-assurance elections technologies and services.

Joe will talk about FETT, DARPA’s first ever bug bounty program, and how FireSim played a key role in FETT’s success. More information about FETT is found here: FETT was a part of the DARPA SSITH program:
