2.1 System Overview
2.1.1 Data Acquisition for Autonomous Driving ECUs
The GETK-P4.0A (Gigabit Emulator Test Probe PCIe) is a Measurement Interface
for Microprocessors and Microcontroller using PCI Express to access Electronic
Control Units (ECUs). Its key functionality is the fast data acquisition from ADAS-
ECUs and to storing the data on a High-Performance PC.
2.1.2 System Interfaces
To process the ECU data, the GETK-P4.0A connects the ECU microprocessors via
PCIe interface. A GETK-P4.0A ECU Driver must be installed on the ECU as part of
the middleware.
2.1.3 Data Transfer
The measurement data from the ECU will be transferred via Ethernet to one or
more Recorder PCs and/or to one or more Visualization PCs. Often the GETK-P4.0A
is connected to an Ethernet switch. At this switch, several other network devices
can be connected.
2.1.4 Setup Overview
The ETAS software RALO is used to control the setup.
Fig. 2-1GETK-P4.0A RALO overview
Beside the GETK-P4.0A and the ECU, one or more PCs installed in the Measure-
ment (Ethernet) network of the vehicle are necessary for the recording, visualiza-
tion and control, configuration or monitor functionalities.

15 | Introduction
ETAS GETK-P4.0A | User Guide
• Configuration functionality
Allows the user to configure and control one or more measurement ses-
sions and to monitor them and all the ETAS measurement devices
installed in the vehicle.
• Recorder functionality
Used to transfer the data with high-speed from the ECU to the Recorder
PC.
• Visualization functionality
Used to analyze and visualize the data. This can be done online during a
running measurement, or offline after the measurement.
The above functionality can be split onto different PCs.
2.1.5 Cascading
Multiple GETK-P4.0A devices or MDH devices can be added to the measurement
setup as well as connected by the cascading interface.
MHD is a Measurement Interface for capturing Video raw signals.
The cascading interfaces delivers the ECU with basic status information general-
ized for the connected measurement devices.
General signals:
- Wakeup
- Present
- Ready
- Replay mode
When using several GETK-P4.0A devices in the same network, make sure they
have a unique IP -address. See as well “Configuring Customized IP Addresses” on
page 29.

16 | Introduction

3.2.1 40/100GE Ethernet Interface to Recorder PC
The GETK-P4.0A is equipped with a 40/100 Gigabit Ethernet connector for connec-
tion to the measurement network(switch) / Recorder PC
3.2.2 PCIe1-4 Interface to ECU
The four PCIe interfaces are connected to the ECU.
Mini-SAS HD cables for PCIe Gen4 can be used to connect the GETK-P4.0A with
the ECU. All necessary signals between GETK-P4.0A and ECU interfaces are
routed via the Mini-SAS HD adapter. The GETK-P4.0A connects the ECU via its
microprocessor interfaces.
3.2.3 CAS-IN Interface
The CAS-IN interface contains control signals like Wakeup, Present, and Ready
between the ECU and the GETK-P4.0A
1GE RJ45 To laptop/PC for service operations
e.g., FW Update..

WARNING
Undefined vehicle behavior due to critical system faults in the ECU software
Disconnections or faulty communication via the PCIe interface can lead to a crit-
ical system error in the ECU software.
Only use the product with ECU hardware and ECU software that are not prone to
disconnections or faulty communication with the PCIe interface
NOTICE
Damage to the electronics due to potential equalization
The cables' shield may be connected to the housing, the ground or the ground
for the product's power supply. If there are different ground potentials in the test
setup, equalizing currents can flow between the products via the cables' shield.
Take account of different electric potentials in your test setup and take appro-
priate measures to prevent equalizing currents.
