The PETracer EML includes a powerful expert system that incorporates detailed
knowledge of the hierarchy and intricacies of the PCI Express protocol specification to
create multiple graphical views of PCI Express data. These Windows
® -based
color-coded graphical views have been optimized for fast and easy navigation through a
captured traffic session. Each packet is decoded to display packet direction, sequence
number, timestamp, packet type and other packet specific fields. Errors are detected at
all levels of the protocol hierarchy and color highlighted for the user. Error conditions
include: DLLP CRC, LCRC, ECRC, delimiter, disparity and symbol errors. Real-time
statistics and post processing traffic summaries give the big picture of the data captured.
Statistics can be viewed in tabular form or viewed in graphical form. Traffic summary
views are hyperlinked back to data traces to quickly jump to the source of bugs.
The PCI Express protocol data can be viewed in several different hierarchical views. Data
can be displayed at the physical layer with Link Tracker to display either 10B/8B codes,
Symbols or hex in either raw or scrambled formats. Traffic can also be displayed at the
packet or Link layer or in the application layer (split view). Placing the mouse pointer over
packet data causes a tooltip with an explanation of the field. Tooltips explain annotations
and often display substantial additional information about selected fields.
The PETracer EML is the first add-in module to utilize LeCroy’s most advanced
Universal Protocol Analysis System (UPAS), the UPAS 100K platform. The expanded
memory buffer of 4GB per direction allows the user to capture deeper traces over a
longer time period. The platform also provides scalability for the future with expanded
hardware capabilities and the capacity for two independent plug-in modules in the same
chassis. The UPAS 100K was specifically designed to support high-speed serial
protocols like PCI Express.
PETracer EML has full x16 lane analysis capabilities as well as many innovative
triggering and filtering options that allows the user to easily diagnose problems and test
for interoperability and standards compliance in order to quickly create marketable
PCI Express products.
