The Partial Reconfiguration (PR) HSSI interface is a unified data interface that connects a network port to the PRBS Generators and Verifiers. The unified data interface consists of a fixed set of physical ports that are mapped to specific signaling functions. The PR HSSI interface also provides clocks for synchronization as well as control and status signals for analog and digital reset sequence orchestration between the PHY in FIM
and the reset controller IP core in AF
. The figure below provides a high-level block diagram for one QSFP instance.
