Challenges of Next-Generation E/E Architectures Development
The automotive industry is undergoing a profound transformation as vehicles become increasingly connected, software-defined, and data-driven, bringing unprecedented complexity to modern E/E architectures.
Exploding software content, massive data flows, heterogeneous hardware platforms, and the shift toward TSN-based zonal and centralized designs demand strict guarantees on timing, bandwidth, safety, and reliability—while also managing cybersecurity, OTA updates, and rapidly evolving performance requirements.
In this environment, traditional manual design methods and late-stage validation are no longer viable, as they lead to costly redesigns, unsafe configurations, integration delays, and architectures that cannot that cannot support updates and reuse over the platform’s lifetime. Ensuring that resource, timing, and QoS constraints are met before implementation is now essential, making a Correct-by-Design workflow critical for detecting flaws early, preventing unsafe designs, and enabling robust and scalable next-generation vehicle platforms.

Addressing Key E/E Architecture Challenges With RTaW-Pegase®
Complexity & Diversity of Communication Protocols and Hardware
Pegase supports a wide range of protocols and network types — from TSN-based Ethernet to CAN/FD/XL, LIN, FlexRay, wireless, gateways and more — all within a single platform. This means engineers can model, simulate and analyze mixed architectures without switching tools or approximating behavior.
Strict Timing, Reliability, and Real-Time Constraints
Pegase offers timing-accurate simulation and mathematical worst-case analysis (using Network Calculus) to compute upper bounds on delays, jitters, buffer usage — long before actual hardware or implementation. It also supports QoS, task and TSN scheduling, shaping, preemption, redundancy, policing, and other mechanisms needed to guarantee reliability under all conditions.
Early-phase Design Validation to Prevent Costly Mistakes
With a “model-based design → automated configuration → simulation/analysis” approach, Pegase enables design-space exploration and early validation of timing, bandwidth, and resource constraints — before implementation. Its built-in tools (e.g., TSN “ZeroConfig-TSN®”, topology optimization, stress testing) allow architects to explore many variants, compare trade-offs (cost, performance, resources), and select optimal designs early following correct-by-design workflow.
Managing Scalability and Future Expansion
(Future-Proof Architectures)
Its Design-Space Exploration and Topology Stress Test® modules let you evaluate how many more functions / data flows the current design can support, and identify bottlenecks or resource limits. By optimizing topology, link speeds, switch placement, routing, and resource allocation, Pegase helps avoid over-dimensioning — reducing cost while ensuring headroom for updates and future features.
Reducing Time-to-Market and Engineering Effort
The proprietary ZeroConfig-TSN® algorithm automates TSN configuration (priorities, shaping, scheduling), significantly speeding up network design. Also, because simulation and worst-case analysis are fast (for large networks, in seconds), teams can iterate quickly on different E/E architectures, compare trade-offs, and converge to a robust design — reducing development time, integration delays, and cost.
Integration of Software and Hardware (Software-Defined Vehicles)
The Software-Defined X module of Pegase allows system-level modeling: you can model tasks, their allocation to processors/cores, real-time scheduling, network communication, OS and virtualization layers — and simulate end-to-end behavior (sensor → CPU → network → CPU → actuator). This unified modeling of both software and network layers helps ensure that timing
