DUT Access
– Scripting: The DUT access is implemented by using scripts to read or set the
relevant registers of the DUT. The BER is measured by reading the error
counters.
If scripting is selected, it is necessary to provide and specify the path of the
scripts. ValiFrame provides batch script templates (such as enable
loopback, read BER register...) that can be filled with any kind of script (e.g.
calling itself a tool or a python script). They can be found in the path:
"C:\ProgramData\BitifEye\ValiFrameK1\AutomotiveEthernet\Settings\
OfflineScripts"
Method
IMPORTANT NOTE:
The scripts have to be adapted to the specific needs of your DUT.
The following options are only available in Expert Mode:
– Manual: In manual mode it is necessary to set up the device and read the
register through any tool to control the DUT. ValiFrame will interactively ask
for the required actions. The BER is measured with loopback analysis.
– Standard: In this case, the scripts are used to set up the device and the BER
is measured with loopback analysis.
Ethernet Device
Script Path It is the path of the script files used to access the DUT.
Keysight recommends that you use a USB to Ethernet gigabit adapter to easily
recognize which port needs to be chosen.
To be able to perform automated tests, the DUT must have the capability to
reset and configure its PHY as well as looping back the received Ethernet data
packages.

Configuring the Ethernet Port
For performing BER tests based on a data loopback analysis, it is necessary to
configure the used Ethernet port of your PC (or the USB-to-Ethernet-adapter) in
the right way:
– The conversion by the APM1000E from Standard Ethernet to Automotive
Ethernet will fail if there is a change of the device speed or duplex setting in
the data flow.
– For tests at 100 Mbps, you must set the PC's Ethernet device (or the used
USB-to-Ethernet-adapter) to 100 Mbps Full Duplex:
Figure 3-9 Configuring the PC’s Ethernet Device for Tests at 100 Mbps
– In the same way, set the Ethernet device to “Auto Negotiation” for the tests at
1000 Mbps:

NOTE
Figure 3-10 Configuring the PC’s Ethernet Device for Tests at 1000 Mbps
If the device is currently at 1000 Mbps and you want to switch it to 100 Mbps,
then you need to change the device's Speed & Duplex to “100 Mbps Full Duplex”
and press the Master/Slave button at the device until flash light change to
yellow. Next, you need to reconnect the USB cable of the device to ensure it
works properly on data loopback analysis.

Configuring Data Rate and Link Role of the APM1000E
The APM1000E has to be configured correctly, depending on the chosen data rate
and link role of the DUT.
If ValiFrame detects a wrong configuration, it displays a dialog with the direction
of the button to press. The dialog will appear again for as long as the
configuration of the APM1000E is incorrect.

Results
Run-Time Data Display
Most procedures generate data output. While the procedure is running, the data
displays in a temporary MS Excel worksheet or HTML page (depending on the
selected viewer in the Station), which opens automatically for each procedure.
The MS-Excel worksheet or the HTML page opened during the procedure run
then are closed once the specific procedure is complete. As long as the AE6910R
software is running, you can reopen each worksheet or page by double-clicking
on the respective procedure. However, the individual worksheets or pages will be
lost when the AE6910R main window is closed unless you saved them.
Results Workbook
You can save all calibration and test data worksheets in a workbook by selecting
File > Save Results as Workbook... at any time. Keysight recommends that this
step is carried out at least at the end of each AE6910R run. If the calibration and
test procedures are conducted several times during the same AE6910R run, the
result worksheets are combined in the workbook. If you conduct a test procedure
without prior execution of calibration procedures in the same test run, only the
test results will be saved to the workbook.
As a safety feature, all calibration and test results are saved by default to the
ValiFrame “Tmp” directory. The sub-folder “Results/IEEE Open Station” contains
the Excel files of the final results measured at each calibration and test
procedure.
In addition to the calibration data worksheets, the calibration data files are
generated. These files are saved by default to the ValiFrame calibrations folder.
Rerunning these calibrations will overwrite the data file. To save the calibration
data files at each configuration, you must copy the files from the directory:
“C:\ProgramData\BitifEye\ValiFrameK1\Automotive Ethernet\Calibrations” and
save them manually in any folder before rerunning the calibrations.

NOTE
Overview
Before running any receiver test procedure, the Automotive Ethernet receiver test
system must first be calibrated.
The DUT input ports give the ValiFrame calibration plane. The receiver test signal
characteristics are typically affected by the signal transmission between the
generator output ports and the DUT input ports. Thus, for any signal output
parameter selected by the user (set value), the signal received at the DUT input
ports (actual value) deviates from the set value. The ValiFrame calibration
procedures compensate these deviations of the relevant signal output parameter
actual values from the set values over the required parameter range.
The ValiFrame software includes all calibration procedures required for
Automotive Ethernet receiver testing. The implemented ValiFrame calibration
procedures are such that the calibration process is conducted as fast as possible
and is automated as much as possible; for example, by minimizing the number of
reconfigurations of the hardware connections.
The LED color of the APM1000E-CLK changes to Magenta if Ext is selected and if
it is not connected to the external clock.
To change the LED color to blue, connect the APM1000E-CLK to the external
clock and repower the device. If the APM1000E-CLK is not connected to the
external clock, ensure the Int is selected and hold Master button while powering
up the device.

Overview
Run all tests with the device set as Master and as Slave.
For Rx tests, the real-time oscilloscope is not needed and can stay unconnected.
The device configuration is not automatic. You are required to implement the bat
scripts or set the device manually with an appropriate tool.
The LED color of the APM1000E-CLK changes to Magenta if Ext is selected and if
it is not connected to the external clock.
To change the LED color to blue, connect the APM1000E-CLK to the external
clock and repower the device. If the APM1000E-CLK is not connected to the
external clock, ensure the Int is selected and hold Master button while powering
up the device.

5.1.1 Indicated Signal Quality for Channel With Decreasing Quality
Purpose and Method
The purpose of this test is to ensure that the PHY indicates a signal quality, having
decreasing values for a channel with increasing noise.
Either manually or through the scripts, the DUT is soft reset, configured to SLAVE/
MASTER and the loopback is enabled. The test automation starts by applying the
minimum noise amplitude and increases it at each step until the maximum value.
For every set value, the SQI value is measured 100 times and averaged.
The following 3 conditions must be fulfilled to pass the test:
– SQI value steadily and monotonic increases/decreases by one step each (the
SQI values are only valid if link-up condition is present)
– Link-up status remains for SQI values higher than 0
– There should be no link instabilities with intermittent link drops for SQI values
higher than 0.
The absolute SQI values may be different from the OPEN Alliance
recommendation in “Advanced_PHY_features_for_automotive_Ethernet”.
In Expert Mode, there are flags to bypass some of those requirements, if the SQI
implementation in the tested DUT differs from the test specification in
“OA_1000BASE-T1 InteroperabilityTest Suite” or
“OA_100BASE-T1_Interoperability_Test_Suite”.

Purpose and Method
Receiver Tests 6
The purpose of this procedure is to verify that the DUT can maintain a bit error
rate (BER) of less than 10
test, the noise source sends idle symbols. The level of the noise is 100 mV
peak-to-peak.
Either manually or through the scripts, configure the DUT to SLAVE/MASTER, and
the DUTs loopback is enabled. In case of testing in DUT access mode “Scripting”
without loopback, reset the Bit Error Counter and Frame Error Counter. Then the
test automation injects noise crosstalk to the signal, and the BER test starts.
The duration of the BER test will be the required time to reach a specified
confidence level (default: 95%). It depends on the capabilities of the PC and the
Ethernet Port. In very unlikely cases, it may take up to 2 hours.
If the looped back data differ from the sent out data, the faulty data packages are
counted as errors (or if the DUT reports transmission errors).
As long as the required amount of transferred bits is not reached, every error
causes the test to fail.

Scripting Details
To run all the tests automatically, ValiFrame controls the DUT by calling batch
scripts.
These scripts are called at special points of the test sequence. Each script has a
specific name reported in ValiFrame Logging-Window.
Some scripts are used to set the DUT into a specific state (e.g.
Enable_LoopBack.bat or Set_LinkRole_Master.bat). Others are expected to return
a value (e.g. Read_SQI.bat), which is read out of the DUT's PMA control registers.
You can implement any suitable logic inside those scripts (calling an executable,
calling a Python or a Tcl script …).
For some chip types, there are available ready-to-use automation scripts, which
can be accessed directly by the Valiframe Automotive Ethernet Test automation.
Contact the local Keysight support to get more information.
The called scripts for data rate 1000 Mbps are as follows:
