SerialLite III Errata
Design Example Components
The design example consists of following components:
SerialLite III Streaming IP core variation
Source fPLL (to generate source user clock in advanced clocking mode)
Traffic generator
Traffic checker
Demo control
Demo management
SerialLite III Streaming IP Core
The SerialLite III Streaming IP core variation accepts data from the traffic generator and formats the data
for transmission. It also receives data from the link, strips the headers, and presents it to the traffic
checker for analysis. The core is generated using the parameter editor in the Quartus II software.
Source User Clock
The fPLL is available only in designs utilizing the advanced clocking mode to generate a user clock for
sourcing data into the SerialLite III Streaming IP core.
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.
