Google OpenTitan: novo chip de segurança de código aberto chega aos Chromebooks
Chromebooks are about to get a lot more secure. Google has begun production of the first commercially available open-source security chip designed to provide transparency & trust in hardware security.

FPGA-based CI is also run on every repository change request to the OpenTitan repository.
It takes a lot of maintenance to keep the stack of FPGAs working.
This is expensive hardware, the latest ones cost up to $10k for each board.
James Wainwright is now presenting "Open source all the way down: developing firmware in parallel with open silicon".
In the context of the OpenTitan open source root-of-trust project, the hardware, its tests and firmware are all developed in lockstep in a monorepo.
Join Dominic Rizzo at 10.00 for his #keynote on #OpenTitan and the past, present, and future of open source secure silicon! #RISCVSummitEurope #zeroRISCInc

Co-simulate CPUs from RTL in #Verilator with @renodeio to run unmodified software in a deterministic simulation. Combine precise CPU models w/ reusable #opensource I/O components to build complete systems simulating e.g. #OpenTitan SoC w/ Ibex @risc_v CPU: https://antmicro.com/blog/2023/01/cpu-rtl-co-simulation-in-renode/

Partnered with @GoogleAI to help build Sparrow, a secure ML platform on @risc_v, #OpenTitan & the @rustlang #KataOS based on the #seL4 microkernel using our #opensource simulator @renodeio. See how we enabled #Rust apps & #GDB debugging for their system @GoogleOSS @seL4Foundation
