NOTE
Specifying InitFC values
If the Logic and Protocol software detects InitFC values in the captured trace, it automatically sets
the InitFC values for performance summary computations based on these discovered InitFC values.
The discovered InitFC values are displayed in the Performance Overview Setup dialog box.
If the InitFC values are not discovered from the trace, default InitFC values displayed in the
Performance Overview Setup dialog box are used for computations.
If you do not want the default or discovered InitFC values to be used, you can edit these InitFC values
in the Performance Overview Setup dialog box. Make sure that you select the Use these InitFC values
checkbox after setting these values.
You can define the maximum flow control credit limits for header and data flow control. To do this,
you can separately define Header and Data InitFC values for posted, non-posted, and completion
transactions for Upstream and Downstream directions.
