 Each report row for the defined tables contains the total number of units in this
group for the CATC Trace (total number of units for Split Transaction perfor‐
mance, Read Requests performance, Memory Writes, and so on).
 In many cases, the Maximum and Minimum values in the report tables are navi‐
gable. By clicking table cells, you reposition the corresponding CATC Trace view
to the Split or Link Transaction that has yielded this maximum or minimum value.
This can help you to find specific units in the CATC Trace, such as transactions
that produced spikes in Response Time or Throughput.

The Bus Utilization window provides graphs for packet‐level information in the
CATC Trace. The window also provides graphs for information on Split and Link
Transaction levels, plotted over time. The graphs for Split and Link Transaction levels are
based on metrics collected for the transactions throughout the CATC Trace.
The seven graphs related to Split and Transaction levels are:
1. Pending Requests at Split Transaction level.
2. Response Time at Split Transaction level.
3. Latency Time at Split Transaction level.
4. Throughput Per Transaction at Split Transaction level.
5. Response Time and Latency Time at Split Transaction level (combined graph).
6. Response Time at Link Transaction level, for Memory Writes only.
7. Throughput at Link Transaction level, for Memory Writes only.
The following is an example of Bus Utilization window display of graph numbers 1, 4, 5, 6
and 7 (see the following figure):
