Quintauris and Nuclei map a safer RISC-V path
4 moves show how Quintauris and Nuclei are aligning automotive RISC-V for production, with NA series safety and RT-Europa requirements.
Quintauris and Nuclei are aligning automotive RISC-V hardware with a production-ready real-time platform.
Quintauris says RT-Europa defines the first comprehensive automotive real-time RISC-V platform spec, and Nuclei’s NA series is now being aligned to it.
| Item | Focus | Notable detail |
|---|---|---|
| RT-Europa | Platform specification | Vendor-neutral target for automotive real-time RISC-V |
| Nuclei NA300 | Real-time core | Compact core for safety islands and low-power control |
| Nuclei NA900 | Real-time processor | High-performance option already used in automotive |
| Nuclei NA1000 | Next-gen compute | Targets newer automotive compute needs |
| NA series safety | Certification | First RISC-V processor IP to reach ISO 26262 ASIL-D |

Quintauris built RT-Europa as a vendor-neutral reference for automotive real-time RISC-V. That matters because automakers and suppliers need more than an ISA profile; they need a full platform target that software and silicon teams can build against.
The spec covers the pieces that make embedded automotive systems predictable and certifiable, including deterministic memory access, interrupt handling, privilege modes, physical memory protection, debug interfaces, and SoC integration rules.
- Deterministic memory access
- Interrupt handling
- Privilege modes
- Physical memory protection
- Debug and SoC integration
2. Nuclei brings the NA series
Nuclei’s automotive line gives Quintauris a processor portfolio with real shipping history. The company points to the NA300, NA900, and NA1000 as the cores being aligned to RT-Europa, spanning compact control use cases through higher-end compute.
That range matters for carmakers because one platform has to cover safety islands, low-power control, and more demanding next-generation compute blocks without forcing each program to start from scratch.
- NA300: compact real-time core
- NA900: high-performance real-time processor
- NA1000: newer automotive compute target
3. ASIL-D safety gives the portfolio weight
Nuclei says its NA series was the first RISC-V processor IP to achieve ISO 26262 ASIL-D functional safety certification. For automotive buyers, that is the kind of proof point that turns an architecture discussion into a procurement conversation.
Quintauris is using that maturity to support the move from evaluation to production. The goal is not just to prove RISC-V can work in cars, but to make sure the hardware base and platform rules are already aligned when OEMs and Tier-1s commit.
Safety signal: ISO 26262 ASIL-D
Deployment signal: several billion Nuclei-based chips shipped
4. Ecosystem alignment is the real story
The cooperation is less about a single chip and more about reducing friction across the stack. Quintauris wants a stable architectural target, while Nuclei wants its automotive IP to fit that target without forcing customers into one vendor path.
That approach is aimed at cross-vendor interoperability, deterministic execution, safety isolation, and easier software reuse. In practical terms, it should help SoC designers move from pilot programs to production roadmaps with fewer surprises.
- Cross-vendor interoperability
- Deterministic execution
- Safety isolation
- Software reuse across product generations
5. The summit showed who this is for
Both companies were at RISC-V Summit Europe in Bologna, where automotive SoC designers, OEMs, and Tier-1 suppliers discussed how RT-Europa and Nuclei’s processors could fit next-generation roadmaps. That audience tells you who the partnership is really aimed at: teams that need a path from architecture choice to shipping hardware.
Quintauris and Nuclei are positioning themselves as coordination points for that transition. If the industry wants real-time RISC-V in cars, it needs a platform spec, proven IP, and a shared target for validation. This announcement ties those pieces together.
How to decide
If you are an OEM or Tier-1, RT-Europa is the piece to watch first because it defines the platform contract. If you are a silicon team, Nuclei’s NA300, NA900, and NA1000 matter because they show how that contract can map to actual processor IP.
If you care most about certification and production readiness, the ASIL-D milestone is the strongest signal in the release. If your main concern is ecosystem fit, the cooperation itself is the takeaway: it narrows the gap between a reference spec and hardware you can ship.
