How RTaW-Pegase will help you design of safe and optimized Ethernet and AFDX networks?

  • Support your design choices by evidence — RTaW-Pegase computes performance metrics such as link loads, communication latencies and buffers utilization that make it possible to predict network performances in all possible use-cases. In addition, RTaW-Pegase offers features to investigate specific scenarios and compare the impact of different design and configuration alternatives.
  • Cost-optimize your networks — RTaW-Pegase provides bounds on the communication latencies that are provably close to the actual worst-case situation, avoiding thus the over-provisioning of resources. In addition, RTaW-Pegase includes design space exploration algorithms to optimize network topologies (e.g., number and location of switches), data streams routing and allocation of the software functions on the stations.
  • Design for the future — using RTaW-Pegase, you know in advance the extent to which your networks will be able to grow in future evolutions of a system.
  • Results you can trust — RTaW-Pegase is no black-box software you have to blindly trust the results of. RTaW-Pegase relies on Network Calculus that is accepted in aeronautics certification, its core algorithms are described in a formal manner in refereed scientific publications – see the technical papers co-authored with our partners.
  • Benefits from years of know-how and experience in mission-critical systems — RTaW-Pegase, which builds on more than 15 years of timing verification research, has been developed in partnership with Onera (see announcement here) and it has been chosen by leading companies from the aerospace and industrial domains – see the companies that trust us.
  • Ready for certification: whatever your application domain and safety standards, we can deliver what you need in certification projects.
  • Best value for money — RTaW-Pegase is not only the most accurate timing analysis tool on the market, it is also less expensive than competitors’ solutions and we provide company-wide license – but don’t take our word for it, request a free evaluation version.
  • Your investment is secured — in order to protect your mission-critical technology, we can contract with you a source code escrow agreement.

Key Features

  • Support industrial Ethernet, automotive switched Ethernet (incl. Some/Ip SD, AVB, TSN time-aware shaper), time-triggered Ethernet (incl. SAE AS6802) as well as AFDX (ARINC664) with arbitrary speeds and topologies,
  • Support worst-case analysis and simulation of heterogeneous communication architectures made up of CAN (2.0A, 2.0B, CAN FD and ARINC825), switched Ethernet, AFDX and ARINC429 buses interconnected through gateways,
  • Support Network-on-Chip for Kalray MPPA and STMicroelectronics manycore architectures,
  • New: analysis and configuration of task scheduling, Event-Triggered and Time-Triggered scheduling, independent tasks, tasks described as graphs and runnables, verification of system-wide timing chains across tasks, networks and CPUs.
  • Implement the state of the art of Network Calculus to compute upper bounds on communication latencies, frame jitters and buffers utilization,
  • Offer both worst-case analysis and timing-accurate simulation with a parallelized simulation engine to predict worst-case and typical performances,
  • New: Higher-level communication layers, run-time environments and applications can be programmed in the CPAL language. This allows the simulation of complete embedded systems,
  • Support FIFO, priority, AVB, TSN and round-robin frame scheduling,
  • Support periodic and sporadic message transmission patterns – possibly with cyclic dependencies,
  • Include optimized priority allocation and routing algorithms,
  • Rich graphical edition and visualization environment with communication architecture editor and Gantt diagrams,
  • Easy import and export of network configurations and simulation results through CSV, XML files and the common formats used in the industry,
  • Maximum pessimism of the computed communication latencies with regard to the true worst-case latencies is limited (typically less than 15%) and is evaluated for each data stream,
  • Include NETAIRBENCH, a benchmark generator to create random yet realistic Ethernet/AFDX configurations for early stage evaluation or to study how the network will be able to accomodate more load in future evolutions,
  • Extremely fast – for instance, large AFDX networks in civil airplanes are analysed in less than 10 seconds,
  • Runs on all 32 or 64 bit platforms supporting Java – no dongle or license server protection,
  • Professional support and custom extensions available. RTaW-Pegase functionalities are also available through software developers SDK for use in your own programs.
