Simplex cores do not depend on signals from an Aurora 8B/10B channel for initialization. Instead, the TX and RX sides of simplex channels communicate their initialization state through a set of sideband initialization signals: aligned, bonded, verify, and reset; one set for the TX side with a TX_ prefix, and one set for the RX side with an RX_ prefix. The bonded port is only used for multi-lane cores.
There are two ways to initialize a simplex module using the sideband initialization signals:
•Send the information from the RX sideband initialization ports to the TX sideband initialization ports
•Drive the TX sideband initialization ports independently of the RX sideband initialization ports using timed initialization intervals
Both initialization methods are described in the following sections.
