3.3.1.3. Traffic Generator

The traffic generator generates traffic in a deterministic format to verify that data is transmitted correctly across the link. Traffic consists of sets of sample words, one for each lane on the link, that are presented to the source user interface.

Figure 22. Traffic Generator Sample Word FormatThis figure shows the format of the sample words generated for each lane.

Description

Word ID

63–59

Contains a static value to distinguish which 64-bit word on the user interface that this sample was presented on. The Word ID value ranges from 0 to (lanes – 1).

Burst Count

58–32

Tracks the number of bursts used to transfer the sample data. This field value starts with one after reset and is incremented each time the start_of_burst signal is asserted on the source user interface.

Word Count

31–0

Tracks the number of valid sample words that have been transferred, across all bursts, to the source user interface.
