The Voyager M3i platform includes 4
GB of recording memory plus USB and
GbE links for uploading recorded traffic
to the host PC. The system also offers
spool-to-disk capture to allow extended
recording sessions (up to the available
disk space). In spooled mode, captured
traffic is uploaded continuously and is
displayed in real-time, making it possible
to see link status and state changes
without stopping the recording. Both
the analyzer and exerciser can utilize
slow clocking (fractional) or external
clock sources (as low as 700 KHz) for
testing with FPGA-based prototypes or
emulators that re quire ultra low-speed
data acquisition.
The heart of the Voyager verification
system is Teledyne LeCroy’s
revolutionary BusEngine™ technology.
This state-of-the-art protocol processing
core incorporates a real-time recording
engine and configurable tools to
selectively trigger and filter on
SuperSpeed USB traffic. Field upgrade-
able firmware allows the BusEngine
to evolve and support new features or
future changes to the USB specification.
Both the analyzer and exerciser can
operate over SMA differential Input/
Output lines to provide a high-fidelity
alternate interface for taping between
development boards.
6th Generation
Analysis Software
The Voyager utilizes the legendary
CATC Trace—the industry’s de facto
standard for USB protocol analysis.
The trace viewer software uses
colors and patterns to train the eye to
understand information faster. When
recording mixed traffic upstream from
a SuperSpeed hub, legacy 2.0 and 3.0
packets are labeled and interleaved in
a single display. Traffic from the logical
2.0 & 3.0 channels can be individually
filtered, searched or exported from
the trace. The USB transfer level can
