Analyzers
In the analyzer mode, the
SPX is inserted between two communicating PCI Express devices, typically
a root complex and an endpoint. The analyzer provides extensive
triggering and filtering, performance analysis, and an intuitive
and detailed capture display of all layers of PCI Express traffic.
Trigger scenarios may be set up for sequential or non-sequential
events, including counter and timer functions. Selectable
trigger events include all ordered sets, packets, K/D characters,
protocol errors, payload data, and other bus events.
Error Check
The captured data is displayed
in an easy-to-understand Catalyst Trace™ view, with various
display options available to quickly zero in on specific transactions,
packets, errors, or other bus events. Alternatively, the user can
elect to view the capture in a list view format, where bus traffic
is represented in hex, 10b, binary, and name convention formats,
by lane and direction.
Packet View
List View
One-touch filters are available to quickly
strip away the physical, data link, and/or transaction layers.
More sophisticated and detailed post-filter options are available
as well.
A detailed statistical report
provides instant qualitative and quantitative information on the
captured bus traffic, including a fast-search feature whereby the
capture instantly jumps to the selected packet or event highlighted
in the statistics report.
Statistical Report
A data payload report breaks
down captured payloads and provides its own statistical summary
on this information, including a byte value distribution graph as
well as additional quick-search features. Additional features include
save-as-text, copy options, quick filters, and various display control
and formatting options.
Data Payload Report
The SPX is offered in two software feature
packages, to better match user requirements with available budgets.
The two configurations are the “Pro” SPX and the “Expert” SPX, with
the Pro versions offering lower cost and the Expert versions offering
a complete suite of advanced features. For details on these configurations
