10.14 Using Unit Metrics
For every protocol unit at the Link or Split transaction level, PETracer™ calculates and
displays a set of metrics. Metrics are measurements of key operating parameters. You can
use metrics to evaluate performance of traffic in the CATC Trace stream.
You can view metrics information in the CATC Trace display, the Traffic Summary window,
and the Bus Utilization window.
PETracer defines different metrics for Link and Split transactions.
