Enabling Production Program Software Development for RISC-V

on YouTube ↗10m

" summary

Toolchain and OS suite targets production RISC‑V programs with standalone compilers and debuggers (32/64‑bit, custom instructions), a MULTI IDE that debugs heterogeneous multi‑core SoCs, and runtime libraries certified to ASIL D and SIL4. Claims include nightly 4 million tests and a 9‑month release cadence; compilers now support C++20. Features: define custom RISC‑V instructions, forward/backward time‑travel debugging, integrations with Python and MATLAB, a few‑KB safety microkernel and the Integrity separation kernel for mixed‑criticality systems.
