Model-Based Design, Automated Configuration and Timing-Accurate Simulation of Automotive E/E Architectures with RTaW-Pegase®

Offer comprehensive support for electronic automotive technologies, including variant management, automated configuration based on requirements, timing-accurate simulation, worst-case performance analysis, and analysis of both simulated and real communication traces.
Provide complete support for Ethernet TSN timing and reliability QoS mechanisms, our ZeroConfig-TSNⒸ design assistant optimizes your TSN network for maximum efficiency.
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 to perform deep timing and reliability analysis, configure scheduling & QoS parameters, and optimize overall system performance.
Enable end-to-end automated configuration and timing verification with support for gateways, tasks, OS, and partitions on multi-core processors with the Software-Defined Vehicles module. Pegase not only addresses the use-cases covered by traditional model-based analysis tools such as SymTA/S® but also augment engineers through advanced automation and synthesis capabilities that streamline workflow, enhance productivity, and optimize system design proactively.
Deliver practical solutions for designing cost-optimized and future-proof E/E architectures using RTaW’s Generative Design technologies.

Testimonial

“Pegase is a comprehensive simulation tool that covers all aspects of current and future Automotive communication needed to verify/validate today’s architectures as well as design for the future.

The GUI is intuitively easy to use, and comes with a flexible plugin environment to add custom functionality however I want.

This combined with the great service makes my work day much more efficient.”
