RISC-V Summit 2022

OpenTitan has brought radical transparency to silicon root of trust (RoT) development. As we approach our first commercial tapeout, this talk will update the RISC-V community on OpenTitan’s status. This talk will cover both the first discrete silicon IC along with the broader development of the OpenTitan ecosystem of compatible IP. OpenTitan IP is permissively licensed, actively maintained, and freely available on Github. Its success is made possible by the project’s focus on commercial partnerships and academic collaborations via the lowRISC Silicon Commons development environment. This has allowed us to create an ecosystem of compatible IP, including the popular Ibex 32-bit RISC-V core.
