The value of the next byte is annotated for TS2, the next 4 bytes for TS1; these bytes may contain
equalization setup information for 8GT/s, if that speed is supported. For TLP, the Type (or Type and Fmt)
are spelled out using exactly the TLP Type names given in Table 2-3 of the PCI Express Base Specification.
For DLLP, the Type is spelled out using exactly the DLLP Type names given in Table 3-1 in the PCI Express
Base Specification.
At 8GT/s, details about the three bytes following SKP END are annotated, including LFSR value (and we set
our LFSR, so we can decode from the first SKIP OS in a waveform that starts in the middle of a data
stream), or in Loopback, Master or in Loopback, Slave or in Compliance, Err Cnt = . Also, if an invalid sync
header is found, UNRECOGNIZED has Details, which are: Invalid sync: and the value of the sync header
(either 0 or 3).

Nominal Rate: This is the nominal bit rate the decoder is currently using to separate bits. Is it not a
measurement. It shows as 2500000000 or 5000000000 or 8000000000.
See Protocol Results Table (on page 19) for general information about the Table display.

You can also Exported your table data as a .CSV file. Touch the Export Table button on the Decode Setup...
dialog and follow the procedure explained in Using The D Supported Protocol Toolsets (on page 14).
PCIEbus Decode Search
The PCI Express Search right-hand dialog appears when the Zoom dialog is shown.
Use the Prev and Next buttons to advance through occurrences. The Search for field allows you to select from
any, Compliance, EIEOS, EIOS, Electrical Idle, DLLP, Logical Idle, SKIP (ordered sequence), TLP, TS1, TS2, FTS, and
UNRECOGNIZED ( at 2.5 and 5GT/s: something that started with K28.5 but did not parse as any possible valid
Ordered Set. At 8GT/s: invalid sync header). The following search parameters are available.
