AUTOMOTIVE TEST

Ethernet and is impedance controlled to
allow for transmission of data in a known
good state. In a fault testing mode, it is
possible to break one or more channels on
an Ethernet transmission, short channels
together, or even connect a channel-toground or battery voltage. The Pickering
family of sensor simulation modules lets
the test engineer simulate sensors ranging from temperature, altitude, dashboard
switches, and even strain gauges. Finally,
as the majority of our products are modular, we can combine high current/high
voltage switching, simulation and FI in
the same chassis."

Khan, Anristu: "For infotainment,
Anritsu offers the Signaling Tester
MD8475B all-in-one base station simulator to test 2G, 3G, and 4G cellular designs; the Bluetooth Test Set MT8852B
for systems utilizing Bluetooth; and the
Wireless Connectivity Test Set MT8862A
supports Wi-Fi. Our Universal Wireless
Test Set MT8870A has been specifically
designed for the high-volume manufacturing testing of devices and systems
using all major wireless technologies.
Anritsu is also currently integrating
the MD8475B with the MT8000A for expanded 5G testing. For testing automotive radar, we have the Spectrum Master
MS2760A Ultraportable Spectrum
Analyzer that weighs less than 1 pound
and covers 9 KHz to 110 GHz."

Chambers, Teradyne: "Teradyne tracks
trends across all automotive systems
and develop production test equipment
for the integrated circuits that are the
building blocks of these systems. For example, our customers use the Teradyne
UltraFLEX system with the UVS64 device power supply to test AI processors at
the core of ADAS systems. The Teradyne
ETS-88 and ETS-88TH systems are deployed to test high- power discrete SiC
and GaN devices and modules used in
electric vehicles. All of these growing
market areas require power management. The ETS (ETS-800, ETS-364 and
ETS-88) systems are used extensively
to test a variety of ASSP and generalpurpose power management devices
found in all automotive systems."

Weiller, Keysight: "Whether they are
an automotive OEM, electronic components supplier, semiconductor chipset
manufacturer, battery and charging infrastructure provider, or compliance
lab-Keysight provides bumper-tobumper test solutions across the whole
ecosystem for their automotive innovations. From radar sensors (in R&D and
manufacturing), automotive Ethernet
networking, connected car communications, electrical powertrain and its
ecosystem, and cybersecurity to general
electronics, Keysight offers a comprehensive portfolio of testing solutions covering the entire spectrum of automotive
electronics."

Software
What tools are available to support embedded software design for automotive
applications, and what challenges do
these tools help customers address?
Sovani, ANSYS: "The amount of automotive software used is rising significantly,
along with the responsibility put upon it.
ANSYS starts with the functional safety
analysis, which checks if requirements
are correct from a safety perspective and
provides feedback. At the requirements
level, we do a cybersecurity analysis.
Companies need to make sure they
have plugged the holes in their software that could be attacked. ANSYS
provides a 3D analysis where we see
if there are areas that are susceptible to attacks and raise a red flag. At
the actual offering of the software,
we provide tools for model-based
design. We can test the software
at the model level and ensure the
models are behaving correctly.
From there, we have a solution that
gives automatic photo generation."
