2.3 Basic concepts of FRstress

Basic Concepts For the test and the validation of FlexRay networks and ECUs it is important to

analyze the behavior in presence of errors. reproducible disturbances in the FlexRay network. Disturbances on protocol level as well as disturbances on physical level are possible.

The graphic below demonstrates the basic function of

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:

The fields frame ID cycle number and of the frame header must be filled up with the desired values.

The field Sync flag indicator of the frame header must be set to

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.

Basic concepts of FRstress User manual FRstress

The functions of this mode are:

¼ Injection of disturbance pattern after a trigger.

This can be used to destroy a specific frame. In this mode a bit synchronous frame manipulation is not possible.

¼ Modification of the bus physics through the configuration of additional resistors

between the bus lines, parallel to the bus lines, to ground and power supply. This is useful for the simulation of various line lengths, shortcuts to ground or power supply and different capacities.

Digital Connection Mode

FRstress divides the network into two segments. The hardware operates similar to an

active star. Frames will be transmitted from one segment to the other segment and vice versa. In contrast to the accuracy are possible too. The optional CRC recalculation completes the function set in that way that bit accurate manipulations are possible. E.g. the Sync flag of a Sync frame from segment A can be set to 0 and the frame CRC will be recalculated. The receiver segment B sees now a valid frame without a sync flag set.

Additional functions are:

Frame filter between the segments

Frame delay between the segments

Use Cycle Count Forecast

The forecast functions can only be used in Digital Connection Mode. The purpose of the forecast mechanism is to trigger on bits in a particular frame which are located before the frame id/cycle count. To use the forecast function, at first it has to be to defined which frame id /cycle count shall be forecasted. Then trigger bits have to be defined which are located before frame id/cycle count in the frame. These bits define the place where the trigger occurs. When a forecast mechanism is activated, the frame id and/or the cycle count are not treated as trigger bits. Note that the network parameters for digital connection mode have to be specified to use the forecast mechanism.

Trigger Parameters Additional parameters for the trigger configuration are located on this page.

Connection Mode Independent

Digital Connection Mode

In this section you can configure the trigger count and the delay between the trigger detection and start of the disturbance.

¼ Disturbance count limitation

If activated the number of triggers can configured in a range between 0 and 255. The trigger action will be executed unlimited if the setting is deactivated.

¼ Delay after trigger detection

The time between the trigger detection and the start of the disturbance execution is configurable. The value range is from 0 to 16777215.

Info: When delay after trigger detection is not 0, the analog frame disturbance tab

is activated because a frame synchronous disturbance is only possible when no trigger delay is set

¼ Auto increment

The delay between the trigger and the disturbance will be incremented automatically with each trigger occurred. The step size will be set in these fields.

The active port for the trigger detection is modifiable in the Digital Connection

Mode. It is possible to select between both ports, port A and port B.

3.5.2.2 Digital Disturbance

Digital Disturbance

The configured disturbance sequence represents a frame modification on bit level.

In the Digital Connection Mode this configuration page is active and in the other connection modes this page is not configurable.

Only those fields that follow the trigger fields (T) can be disturbed.

Configuration pages User manual FRstress

As disturbance values for the bits Data_0 (0), Data_1 (1) and undisturbed (u) are

allowed. The frame fields with its meaning and representation are explained on the Frame Trigger Configuration page. For frame ID, payload length, header CRC, cycle count, CRC 1, CRC 2 and CRC 3 values can be entered numerical (hex or dec) by clicking on the link left of the corresponding edit box.

Exception 1: When delay after trigger detection or auto increment isn’t 0 (trigger

parameter page), the analog frame disturbance tab is activated.

Clear fields This button clears all fields on digital frame disturbance page.

Show Trigger Bits This button shows all frame fields which are already used by the trigger definition.

Exception 2: Trigger/Disturbance 1 and Trigger Input → Disturbance sequence 1

These bits can not be used in the disturbance sequence. Normally the disturbance sequence follows the trigger sequence.

Configurator The selection dialog for database messages is started. A symbolic message can be

selected. The data of the frame will be inserted in the corresponding fields after selection:

¼ Load Frame Id

¼ Load Payload length

¼ Load Frame Id and Payload Length

Use Continuous Disturbance

If selected all frame disturbance fields will be deactivated. Instead of the synchronous disturbance the continuous disturbance is executed when the trigger occurs. The continuous disturbance can be defined on the corresponding configuration page.

3.5.2.3 Analog Disturbance

Analog Disturbance

This page holds the settings for the disturbance sequence in the Analog Connection Mode. In all other connection modes this page is deactivated.

The disturbance sequence in the Analog Connection Mode runs asynchronous to the detected trigger sequence. Due to reflection effects on the bus line it is possible that not all nodes in the net-work see the same disturbance on the bus.

Exception1: This page is also activated in the digital connection mode, when

delay after trigger detection or auto increment is not 0 (trigger parameter page).

Exception 2: This page is also activated when Trigger/Disturbance 1 and Trigger

Analog Disturbance The resistor and capacitor network for analog disturbance is defined here.

Analog disturbances may be caused by the following in a real FlexRay network:

¼ Short circuits

¼ Isolation faults

¼ Poor contacts

Configuration pages User manual FRstress

Disturbance Parameters

The following disturbance parameters may be used to configure the disturbance state:

¼ R_HL

for simulating contact resistances between wires (e.g. isolation faults, humidity, short circuits)

¼ R_H

for simulating contact resistances to disturbance voltages

¼ R_L

for simulating contact resistances to disturbance voltages

¼ R_SH

for simulating length resistances in wiring (e.g. poor contacts or wire breaks)

¼ R_SL

for simulating length resistances in wiring (e.g. poor contacts or wire breaks)

¼ C_HL

for simulating longer bus lines at low baud rates (only makes sense for LowSpeed buses)

Hints Essentially the individual disturbance parameters can be connected or disconnected

by clicking the relevant component in the circuit diagram.

If a resistor is disconnected the associated input field, in which the user enters a

resistor value for this resistor, is disabled for user input.

The resistors and the capacity are active as soon

FRstress is connected to the

Software Trigger Action

Software Trigger reaction: In this section the specific behavior of the software trigger

For the external trigger input it is possible to define whether the input should be used as an external trigger or as a trigger enable signal.

When used as an external trigger the user can choose whether the input should be a Level trigger (with LOW or HIGH level) or an Edge trigger (with triggering on the transition from LOW→HIGH or from HIGH→LOW). Additionally the assigned disturbance can be configured. You can decide for one of the following settings: no disturbance, disturbance sequence 1 or continuous disturbance.

When used as a trigger enable signal, the user can decide whether, when a trigger condition is satisfied, there must also be a low (LOW) or a high (HIGH) voltage level at the input to permit triggering.

This setting describes the general behavior of the software trigger.

¼ Button pressed (single shot trigger):

4.1 Interfaces

Supported Interfaces The FRstress hardware has the following interfaces:

¼ Y-Adapter to the FlexRay bus

¼ Trigger Output

¼ Trigger Input

¼ Sync Line

¼ USB

¼ Power Connector

4.1.1 Y-Adapter to the FlexRay bus

Bus connection The bus connection is similar to the way CANstress is connected to the bus. An

adapter cable connects the pin connector to two DB-9 connectors (one male connector and one socket).

FRstress hardware to a bus. The cable converts the 15

Signal DB-9 connector

4.1.2 Trigger Output

Trigger Output The trigger output is realized as BNC connector. The output uses the same ground

like the trigger input. The output generates TTL signals.

4.1.3 Trigger Input

Trigger Input The trigger Input is realized as BNC connector. The input accepts TTL signals. The

input is electrically isolated to the remaining hardware.

4.1.4 Sync Line

Sync Line The Sync interface is realized as BNC connector. The sync line interface uses the

same ground like the trigger interfaces. The interface bases on TTL signals.

User manual FRstress FRstress Hardware

4.1.5 USB

USB The USB port is fed out via a four-pin connector (Binder Series 711) and conforms to

the USB standard 2.0.

4.1.6 Power Connector

Power Connector The connector is realized as a 5 pin plug of the plug series “Binder 711”.

Using Pin 5 of the Supply connector it is possible to set the housing ground to a defined voltage level. When utilized in a motor vehicle, a direct connection to the negative supply voltage (vehicle ground) presents itself as an option. If relevant to the specific area of use, it may be advisable to make a connection to the ground conductor of the installation. If Pin 5 is left unconnected (this is the case on the voltage cable provided), no voltage level is applied to the housing.

4.2 LED Indicators

Status indication Four LEDs display the current state of the FRstress hardware.

The first LED (Power/Run) is located nearest to the side with the plugs.

Startup mode

Normal mode

The LEDs flash together until the hardware is detected by the PC.
