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.
