Configuring and Computing Decoded Transactions
Before you Start
• You should have purchased and installed the U4301
Transaction Decoder
license for computing
decoded transactions.
On purchasing the license, you receive an entitlement certificate. Follow the instructions in this
certificate to install the license.
• Ensure that the data in the required direction(s) is already captured and available in the Logic and
Protocol Analyzer GUI for transaction decoding. You may save the captured data in a Logic
Analyzer configuration (.ala) file and access this data offline for transaction decoding.
• It is recommended that you capture the device’s complete boot process data so that the required
device setup details such as AHCI base address and port addresses in case of an AHCI device are
available for decoding transactions accurately.
Computing Transactions from the Captured Data
1 Click the
Transaction Decode
tab in the Protocol Viewer window.
2 In the
Data Range
groupbox, specify the start and end points of the captured PCIe data for which
you want to compute decoded transactions. Only the specified range of data is analyzed to
compute transactions. Following options are available for setting the data range.
•
Beginning and End of data
- This data range selection ensures that transactions are computed for
the entire trace.
•
Trigger
- Selecting Trigger in the data range ensures that transactions are computed from the
point where the U4301 module’s trigger condition was met.
•
Markers
- Selecting markers in the data range ensures that transactions are computed for the
specific portion of PCIe traffic defined by markers. Refer to
“Defining Markers for Setting the
on page 116 to know more.
3 Click the
Compute
button displayed with the Data Range fields.
NOTE
Compute This
and
Compute All
are the two options available with the Compute button.
- Compute All allows you to compute traffic overview statistics, decoded transactions, offline
performance summary, and LTSSM states (in their respective tabs) for the captured packets
by a single click of this button.
- Compute This allows you to compute only decoded transactions from the captured packets.
When you click Compute, then also only decoded transactions are computed.
