CAN
and LIN Timing and Protocol Decode Software
TDSVNM CAN and
LIN Timing and Protocol Decode software transforms Tektronix digital
oscilloscopes into sophisticated in-vehicle network management tools
that provide industry-leading trigger capabilities, oscillator tolerance,
propagation delay measurements, and simultaneous protocol decoding
of CAN and LIN messages that help to ensure seamless and reliable
operation of the network. TDSVNM can be installed on Tektronix real-time
Windows oscilloscopes and - when used with Tektronix embedded triggers
or the Crescent Heart Software's ATM1 automotive trigger module -
provides a sophisticated in-vehicle network management tool.
Seamless CAN Network Operation
The industry’s finest timing
measurements in TDSVNM make it an ideal tool for debugging problems
for seamless operation of a CAN network. TDSVNM provides oscillator
tolerance and propagation delay measurements enabling proper setting
of the sample point in bit time. This ensures accurate sampling of
incoming CAN messages in an asynchronous CAN network. Data rate measurement
quickly identifies mismatch in data rates in any of the CAN nodes
in the network. Mismatch in data rate can cause a series of error
messages to be generated, hampering network performance.
Electrically,
the automotive environment is noisy. CAN eye diagram analysis quickly
pinpoints problems caused by excessive jitter, amplitude aberration,
spikes and glitches in CAN messages.
CAN and LIN Protocol
Decoding
TDSVNM makes it very easy to interpret NRZ encoded
information in CAN and LIN messages. This software coverts the time
domain information into Data Link layer information (Hex or Binary)
in CAN or LIN format, saving valuable design time. Time stamp information
provided by the TDSVNM software quickly measures the latency time
between the two associated messages for quick characterization, and
debugging network performance. Using the zoom features, you can now
easily view the specific CAN message at higher resolution during long
time capture of the CAN/LIN traffic using the long acquisition memory
of the oscilloscope.
The industry’s first simultaneous protocol
decoding of CAN and LIN data from two segments of an in-vehicle network
makes TDSVNM a highly recommended tool for current and future needs.
With this capability, engineers can easily ensure the accuracy of
communication and the acceptable latency time for exchanging information
across a gateway.
Capture CAN and LIN Data
The powerful
trigger capabilities offered by DPO7000 Series' internal CAN triggers
and the ATM1 automotive trigger module, coupled with the TDSVNM’s
graphical user interface, make this solution one of the best suited
to analyze CAN and LIN Traffic at specific conditions. By triggering
on any of the CAN frame types and its bit value, engineers can debug
difficult problems easily.
The advanced trigger capability
of ATM1 offers unparalleled trigger capabilities to debug and characterize
network performance at different operating conditions of the vehicle.
Using advanced trigger setup, you can now monitor multiple trigger
conditions, and take multiple actions that enable long time monitoring
of CAN traffic and capture the specific event of interest.
