Performance analysis
Visualize the performance of your PCIe traffic with the built-in statistics provided by the
Performance Overview of the U4301B. Over 50 parameters are automatically calculated
and with simple checkbox selection all of the performance information is displayed in a time
correlated graphical overlay view. The statistical performance of the link latency, utilization,
and Flow Control credits, is shown with events such as Interrupts and errors.
Figure 15. The statistical performance of the link latency, utilization, and Flow Control credits, is shown with events such as Interrupts and errors.
Flow control analysis
Flow control computes and displays the available flow control credits from the data trace that
has a bidirectional traffic. Flow control credit level is determined by the Writes and Completions
in one direction and the UpdateFC packets in the other direction.
