Caliptra: Building Open Source Security IP with Open Source Tools
summary
Caliptra is an open-source root of trust developed jointly by Nvidia, Google, Microsoft and AMD and targets a near-term 1.0 RTL release intended for real-world server SoCs. Work reuses the ver e2 core formerly swerve, runs CI with Verilator, Cocotb/pyUVM and GitHub Actions, and uses riscv-dv (including a riscv-dv python front end) to find and fix RTL/firmware bugs. FPGA runs target UltraScale+ ZC104, OpenROAD flow is in progress, and five Caliptra talks appear at the OCP summit.
