3 Hardware Description
This chapter provides an overview of FlexRay and the ES920.1 module and pro-
vides you with information on its properties, connectors and the LED.
3.1 Overview
3.1.1 FlexRay
The complexity of vehicle electronics is permanently on the increase due to the
increasing number, growing function scope and the networking of electronic
ECUs in vehicles. Error-free functioning of the systems is essential for safety
applications such as X-by-Wire (e.g. for the brake system or steering). This
requires, for example, reliable and real-time-capable data transfer between the
electrical and mechatronic components.
The new powerful FlexRay bus system fulfils these demands. It has a range of
innovative functional and safety features with which system safety in vehicles can
be improved. The FlexRay bus system enables data rates of up to 10 MBit/s in a
topology of point-to-point connections, active stars and mixed systems. Typical
of this topology are, for example, ideal bus terminations and thus minimized
reflections, defined electrical behavior, flexible expandability, error delimitation
on affected branches and optimized EMC behavior.
The importance of the standardized FlexRay bus system is permantenly on the
increase in development projects in the automotive industry. Due to redundant
data transfer, FlexRay can also be used in safety-critical applications and the
deterministic structure enables messages to be transferred reliably.
The signals to be monitored can be selected from the set of all signals available
in the connected cluster. To obtain the corresponding information, the FIBEX file
is imported to INTECRIO. INTECRIO then uses the FIBEX file to configure the
FlexRay hardware.

ES920.1 - User’s Guide 15
ETAS Hardware Description
3.1.2 Definitions
FlexRay
FlexRay is a scalable and fault-tolerant communication system for deter-
ministic data exchange at high transfer rates. Using the time multiplex
procedure enables the creation of distributed systems with a highly mod-
ular structure and high safety demands. The high bandwidth of 10 MBaud
on two channels plays its part in overcoming high network loads caused
by the increasing number of innovative electronic systems in modern vehi-
cles.
The specifications of this communication system are issued by the FlexRay
Consortium, a committee which is supported by a large number of vehicle
manufacturers and suppliers worldwide.
FIBEX
FIBEX (Field Bus Exchange) is an XML scheme based exchange format
used to describe the entire communication network in the vehicle. FIBEX
is designed for various types of network (CAN, LIN, MOST, FlexRay) and
includes information on bus architecture, signals, properties of the net-
work nodes etc.
INTECRIO uses FIBEX files to coordinate software tools and ECUs and the
communication scheme dictated by the FlexRay cluster, i.e. the FIBEX file
defines, amongst other things, the signals. It also contains data to config-
ure the hardware interface. The FIBEX files have to be made available by
the vehicle manufacturer.
More information on the FIBEX standard can be obtained from
http://www.asam.net.

3.2.1 Features
The ES920.1 FlexRay Module, when accommodated in the extension slot of the
ES910 Rapid Prototyping Module, enables rapid prototyping applications at Flex-
Ray channels.
Together with the ES910, the ES920.1 module is part of a highly efficient, com-
pact development and experimental platform with high computing and simula-
tion performance due to the use of a close-to-target, fast floating-point
processor. The AUTOSAR-compatible RTA-OSEK operating system of the ES910
guarantees simple transition from the finished function prototype to ECU soft-
ware development.
The ES920.1, equipped with the Bosch E-RAY IP, provides a FlexRay node with
the channels A and B which can send and receive FlexRay frames. Interrupts can
be triggered at cycle, segment and slot level.
To optimize system performance, a preprocessor handles the FlexRay communi-
cation paths independently from the simulation controller of the ES910.
Together with the ES920.1, the ES910 is hardware optimized for rapid prototyp-
ing applications used to develop FlexRay ECUs.
The ES920.1 is configured entirely in INTECRIO.
Overview of the Major Features of the ES920.1:
• One FlexRay node with two FlexRay channels which can be used redun-
dantly
– Channels galvanically isolated from each other, from the device
ground and from the supply voltage
– “Wake Up” via FlexRay
• Efficient connection of the ES920.1 FlexRay port to the ES910 simulation
controller
• Use of the BOSCH E-Ray IP Module as a FlexRay Communication Control-
ler, compatible with the FlexRay Protocol Specification V2.1
• Support of future FlexRay versions with firmware update
• Configuration possibilities in the calibration software:
– Data rates of up to 10 MBit/s
– Max. 128 frames
– 8 kByte message RAM, for example
to save 128 frames with max. 48 byte payload or
to save 30 frames with max. 254 byte payload
– Slot counter filter, cycle counter filter and channel filter
– Network management support
Note
The ES920.1 FlexRay Module can be operated in the extension slot of the
ES910.2 and the ES910.3-A.

ETAS Hardware Description
• After integration into the ES910, the ES920.1 is a module suitable for use
in automotive applications which is perfect for use in the development
environment and in the vehicle on test drives.
– Not sensitive to extreme environmental conditions (temperature, EMC)
– High mechanical stability and durability
• Part of the ETAS Tool Suite
– Rapid prototyping of control functions with MATLAB®/Simulink®,
ASCET-MD as well as C by integrating into INTECRIO
– INTECRIO supports:
FIBEX import to configure the FlexRay node,
The simple allocation of the signals required for control and diagnostic
functions to the FlexRay frames,

3.2.4 LEDs
The ES920.1 has one LED, T, which displays the functional state of the FlexRay
node. When the ES910 is powered on, the following functional states are dis-
played:
LED Display Functional State

4 Functional Description
This chapter describes the block diagram, bus termination, the “Wake Up” and
“Sleep” functions and also provides tips on the firmware update.
4.1 Block Diagram
The ES910 has a slot for extension modules (extension slot). This slot can, for
example, accommodate the ES920.1 FlexRay Module.
Fig. 4-1Block Diagram of the ES920.1
4.2 Bus Termination Resistor
The FlexRay specification makes it possible to create different bus topologies,
such as a passive bus, passive star or active star.
Each of the topologies requires the relevant bus termination. The FlexRay termi-
nation designated by the ETAS FlexRay specification is 100 Ohm. To support the
creation of a rapid prototyping environment in FlexRay networks, ETAS provides
FlexRay cables with corresponding FlexRay terminations. The termination has to
be connected to the cable or to the connector.
4.3 “Wake Up” and “Sleep” Functions
The ES920.1 module supplements the “Wake Up” and “Sleep” functions of the
ES910 module with further control possibilities. The ES920.1 can control the tog-
gling of the overall system ES910/ ES920.1 in the vehicle between on and
standby.
The overall system ES910/ ES920.1 can effectively be in three different states:
Off, Standby and On.

4.3.1 “Wake Up” Function
“Wake Up” Conditions
There are two different “Wake Up” conditions in the system:
• when FlexRay traffic is detected or
• when the FlexRay “Wake Up” pattern is detected.
Definition of the FlexRay “Wake Up” Pattern.
If the ES920.1 detects the “Wake Up” pattern defined in Fig. 4-3 on page 20 ,
the ES910/ ES920.1 system changes from “Standby” to “On”.

Note
The ON/AUTO switch of the ES910 must be switched to AUTO for this func-
tion to be able to be used.
