2.1 Overview

At a glance With FRstress the user can intentionally and reproducibly disturb the FlexRay bus, its

physical characteristics and the logical level.

The test scenarios consist of the definition of trigger conditions and corresponding

actions like disturbance or activation of a trigger output. With the start of
measurement a set of four tests can be transferred to the hardware for execution.

Although hardware can only disturb one channel it is possible to configure test
scenarios for both channels of a FlexRay cluster. The software provides the support
of two hardware devices.

well as disturbances on physical level are possible.

analyzes the bit stream on the FlexRay bus and compares the data with the active
trigger streams. As soon as a trigger condition matches, the trigger output is
activated. Additionally to the active trigger signal a dedicated disturbance manipulates
the FlexRay bus. The kind of disturbance depends on the active operation mode of

FRstress.

Basic Functions

FRstress supports you to generate

FRstress. The hardware

FRstress provides three different operation modes. The following chapters give an

overview about the trigger definition and the operation modes.

2.3.1 Trigger definition

Trigger Definitions Altogether four parallel trigger definitions can be defined. The trigger is defined by a

sequence of
bus the trigger will be activated.

The software provides a FlexRay frame oriented input mask for the trigger definition.

All elements of the FlexRay frame and the frame coding (e.g. Byte Start Sequence)
are available for the trigger definition.

These are examples for possible trigger definitions:

2.3.2 Operation modes

Pure Scope Mode In this mode FRstress is passive to the FlexRay bus. It analyses the bit stream on the

bus and generates the appropriate trigger signals. The disturbance part is switched
off.

This mode is useful for pure triggering where no disturbances are required. An

oscilloscope is a typical receiver of the trigger signal.

Analog Connection
Mode

Additionally to the trigger definition it is possible to define disturbance sequences.
These sequences will be activated after the detection of the assigned trigger. This
means that the earliest point in time for the start of a disturbance sequences is
immediately after the trigger the detection of the last trigger bit.

FRstress is connected to the bus in normal node.

Info: In this mode the transceivers of FRstress transmit in one case against the

transceiver of the sending node and in the other case with the sending transceiver.
This is reflected in the fact that depending on the line position in some case the
desired disturbance can not guaranteed. This means the disturbance can be
influenced by the length of the bus cable, the termination, the transceivers and the
position of the receiver node.
