FRstress: Leistungsstarkes Modul für reproduzierbare Störungen auf dem FlexRay Bus

FRstress - High-performance Stress Module for Reproducible Disturbances on the FlexRay Bus

Functions

  • Generation of asynchronous and synchronous disturbance sequences
  • Modification of individual frame bits including CRC recalculation
  • Switch-in RC network with adjustable resistances and an adjustable capacitor
  • Switchable connections between the bus lines, to ground and to supply voltage
  • Trigger logic to detect different positions in the FlexRay frame
  • 4 parallel trigger conditions and associated disturbance sequences
  • Configuration via FIBEX data-
    bases
  • Trigger output to drive external devices
  • Synchronization capability for parallel operation of two FRstress modules

 

What is FRstress?

FRstress generates reproducible disturbances in FlexRay systems. It can generate protocol errors as well as disturbances in bus physics that are activated by trigger conditions.

FRstress is an easy-to-use hardware module whose integration in the system differs depending on the desired disturbance.

Overview of Advantages

  • Easy testing of disturbance handling in FlexRay systems and nodes
  • Reproducible simulation of line problems
  • Comfortable configuration and control via a user-friendly Windows-based
    operating program
  • Various trigger conditions, disturbance sequences and values of line resistors and the capacitor for analog disturbances
  • Integration in CANoe test environment

Application Areas

FRstress is the ideal tool for testing disturbance handling in FlexRay systems and nodes. It enables reproducible simulation of line problems.
