Speed-up Design Exploration, Optimization and Validation of Next-Generation Software-Defined Systems

Software has become the key to innovation and is transforming entire industries. While the intensive use of software opens up vast opportunities for innovation, customization, and differentiation, it also introduces complex challenges for E/E architectures — challenges for which RTaW-Pegase supports effective decision making:

Growing number of safety-critical, compute-intensive functions like Advanced Driver Assistance Systems (ADAS) and automated driving,
Need for high-performance and timing-predictable networking solutions to cope with the dramatic increase in bandwidth demand, driven by the growing number of data-intensive sensors with asymmetric bandwidth requirements such as cameras or lidars,
Integrating numerous Electronic Control Units (ECUs) into a few high-performance, multi-domain integration platforms with built-in redundancy and advanced compute capabilities,
Real-time vehicle-to-cloud communication and Over-the-Air (OTA) updates,
Scalable E/E architectures for safety and performance, tailored to different vehicle classes in a cost-effective way – as explored in this study by R. Bosch and Cognifyer, RTaW’s research lab,
Ensuring predictability in complex execution platforms with multiple OSes, an hypervisor, and service-oriented middleware running on SoCs with heterogeneous cores – see this study by Volvo Cars and Cognifyer.

Key Features

Enable the modelling of real-time software executing on processors as tasks communicating via messages and signals, locally or over a communication network,
Support design decisions related to task allocation to processors and cores, scheduling policies, and task activation patterns,
Enable to model system-level timing chains (e.g., between sensors and actuators) across processors and networks within the embedded system,
Provide firm guarantees that processor loads remain within budget and task timing constraints are met,
Enable proper buffer sizing to prevent message losses,
Support Service-Oriented Architectures (SOME/IP, DDS, MQTT) and ensure services are consistently delivered on time,
Enhance your existing workflows by seamlessly importing into Pegase your E/E architecture designs from upstream architecture modelling tools such as PREEvision® via AUTOSAR .arxml or CAN .dbc files. Pegase enables you then to perform deep timing and reliability analysis, configure scheduling & QoS parameters, and optimize overall system performance,
Offer timing-accurate simulation and worst-case response time analysis for software functions, network transmissions, and sensor-to-actuator timing chains, covering the use-cases of traditional model-based analysis tools such as Symta/S® and augmenting engineers through advanced automation and synthesis capabilities.
Support for modern high-performance computers models with hypervisors,
Offer rich visualization tools (e.g., Gantt charts, load displays) to understand system timing behavior in both nominal and edge cases,
Quantify system extensibility in terms of spare processor capacity and the number of additional functions and services the architecture can support,
Explore architectural and technological design options on models, enabling performance- and cost-driven design choices early in the design,
Leverage Pegase’s networking modules for comprehensive system-level verification for distributed functions.

Testimonial

“The competition in the smart electric vehicle (EV) market necessitates the swift introduction of new features. This, in turn, demands a new generation of EEA (Electrical and Electronic Architecture) and communication technologies. The implementation of a brand-new tech stack results in challenges when addressing communication and task scheduling problems. RTaW’s SDV functionality enables us to model the temporal behavior of the vehicle and conduct insightful analysis of each activity chain. Throughout this process, the tool provides various scheduling models, state-of-the-art simulation algorithms, and, with RTaW’s robust support, assists us in identifying the traffic and CPU peaks of the system. Ultimately, it helps us pinpoint the appropriate solution. RTaW-Pegase plays a crucial role as a key tool in the development of next-generation EEA.”
