Converting I-Tech Files

Channel mappings and nomenclature

Converted traces use a "Port" naming convention that is common to the Xgig platform
architecture. When an I-Tech analyzer trace is converted, the following names are utilized in the
Xgig format:

Ports 32-63 may or not be created following conversion, depending upon the data within the trace.
These ports are only created as necessary. These ports will not be visible in Xgig Expert and it will
handle them automatically. The conversion program that imports I-tech SAS/SATA capture files
does not currently support primitive sequences within a frame (for example, ALIGN, RRDY,
SATA_HOLD, SATA_HOLDA). The occurrence of any primitives within a frame will be placed
in an additional port number that is 32 higher than the original port number.
In the Xgig trace format, each port (or channel) represents a single transmitter. Each port is saved
to a separate file (with the .BUS extension for SAS traces, .TRC for Fibre Channel trace and .GBE
for Gigabit Ethernet traces). Additionally each of the filenames/locations are placed into a .TGP
file (Trace Group File), which is the file type that is opened by default in both Xgig Expert and
Xgig TraceView.
