As SDV stacks grow more complex, open software must prove it can scale under series, safety and lifecycle constraints. Paula Herzog of Qorix explains how Eclipse S-CORE can be hardened for real-time, automotive-grade deployment.

As software-defined vehicle programs become more complex, the industry is under growing pressure to turn flexible software architectures into robust production platforms. Open-source building blocks are gaining importance in that effort, but series programs still demand stability, traceability, safety alignment and long-term maintainability.

Paula Herzog, Head of Product Program Management at Qorix, addresses exactly this tension in her presentation at the Automotive Software Strategies Conference 2026 in Munich. Drawing on experience from Bosch, ZF and now Qorix, she discusses what it takes to make Eclipse S-CORE production-ready for safety-critical and real-time embedded systems.

Ahead of the event, we spoke with her about the industrialization challenge behind open automotive software platforms.

ADT: Looking ahead three to five years, what will be the biggest challenge in bringing open software platforms into series automotive programs?

Herzog: The hardest part won’t be building open software platforms. It will be industrializing them – turning promising technology into something a series automotive program can actually base its schedule and safety case on. Open-source innovation moves fast. Automotive programs need stability, predictability, and compliance with functional safety standards such as ISO 26262. In practice, we’re seeing a widening gap between what the upstream community ships and what OEM programs can actually deploy. Closing that gap is not primarily a technology problem. It’s a question of ownership, governance, and lifecycle discipline. The industry has spent the last few years exploring what open source can do. The next phase is about making it work at scale – repeatedly, reliably, and under real program conditions.

Which platform decision today will most strongly shape how open middleware scales across SDV programs?

The most consequential decision is deceptively simple: is middleware treated as a shared, non-differentiating foundation, or does every program rebuild and reintegrate it from scratch? OEMs that standardize this layer early gain a compounding advantage. A stable middleware foundation scales across domains, platforms, and vehicle generations. Those who don’t will keep paying the same integration tax, program after program. What we consistently see is that success comes down to a clean separation of concerns – hardware, operating system, middleware, applications – and ensuring that the middleware layer is robust enough to carry not just one program, but many. Get that architecture right once, and it pays dividends for years.

Your presentation focuses on distributing Eclipse S-CORE for safety-critical systems. What does it take to make an open project production-ready?

Production readiness is about everything that doesn’t show up in the code. Functional safety alignment, traceability, test coverage, release management, and long-term maintenance – none of that is visible in a repository, but all of it is what an automotive program actually depends on. Add to that the integration work across SoCs, operating systems, and real-time environments, and you start to see why “open source” and “production-ready” are very different claims. At Qorix, we address this by pairing open-source collaboration with a production-grade distribution model. The open project provides the shared baseline. Production readiness is achieved through systematic hardening, validation, and the kind of support structures that OEM programs can build a program plan around. We demonstrated this concretely at CES – four end-to-end demonstrators across different partners, platforms, and use cases, all running on a consistent middleware foundation. What became clear is that production readiness is not about individual features. It’s about making complex, mixed-criticality systems behave reliably across real automotive environments.

What role does a distributor play when scaling open middleware across multiple OEM programs?

The distributor is where open-source innovation meets program accountability. Open-source communities are exceptional at collaboration and feature development. But they are not structured to carry the full responsibility for an automotive program – and they shouldn’t have to. The distributor closes that gap by owning integration, validation, compliance, and lifecycle support across the full vehicle lifecycle. That role becomes critical at scale. When you’re running middleware across multiple OEM programs simultaneously, consistency and predictability aren’t optional. You need a single point of accountability – someone who can align with program timelines, absorb the complexity, and ensure that what ships in one program can be maintained and updated in the next. In that sense, the distributor doesn’t just enable technology adoption. It’s what makes adoption sustainable.

Where do real-time and safety requirements create the biggest challenges when turning open software into automotive platforms?

Real-time and functional safety requirements change the rules fundamentally. It’s no longer enough for software to be correct – it has to be deterministically correct under all conditions, with strict guarantees on timing, isolation, and data consistency. That’s a different engineering problem from what most open-source development is optimized for, and it’s frequently underestimated in early-stage projects. The hardest part is runtime orchestration in mixed-criticality environments – where safety-relevant and non-safety functions share the same hardware platform. That’s where the gap between “open code that works” and “automotive-grade middleware” becomes most visible. And it’s exactly where dedicated architectural investment pays off.

How can OEMs ensure long-term maintainability when integrating open components into complex SDV stacks?

Long-term maintainability is less a feature question and more a governance question – one that gets harder the longer it’s deferred. The technical foundations are well understood: modular architectures, stable interfaces, strict versioning. But the real challenge is managing change over a vehicle lifecycle that stretches 10 to 15 years. Updates, compliance requirements, security patches, evolving safety standards – none of that stops after SOP. What OEMs actually need is clear ownership of lifecycle management: who is responsible for integration stability, who owns the update strategy, and who ensures ongoing alignment with functional safety and cybersecurity requirements. Without that structure, open components that looked like assets at the start of a program can quietly become liabilities by the end of it. The good news is that well-architected stacks – with clean interfaces and active upstream communities – give OEMs real optionality. Switching costs exist, but they are manageable. The risk isn’t open source. The risk is choosing a partner who doesn’t know how to play the long game in an open world.

Finally, what do you personally hope to take away from the Automotive Software Strategies Conference in Munich?

Honestly? Fewer hypotheticals and more commitments. There is strong alignment across the industry around the idea of shared, open software foundations like Eclipse S-CORE. What I’m hoping to drive at this conference is the next conversation – not “should we do this?” but “how do we actually operationalize it across programs, across partners, at scale?” I’m particularly interested in concrete discussions with OEMs and Tier-1 companies on closing the gap between strategic intent and production execution. That’s the conversation that moves the industry forward – and Munich is exactly the right place to have it.
