XCVR_RECONFIG_GROUP
Assigns the node you specify to a transceiver Avalon Memory-Mapped interface group. The Avalon
Memory-Mapped interfaces of an RX-only channel and a TX-only channel, or a CDR PLL and a TX-only
channel, can be merged and placed into one transceiver channel. You can assign this option to the
instance names of the transceiver Avalon Memory-Mapped interfaces you want the Fitter to merge. You
can also assign this to option to a CDR PLL instance name and the transceiver TX (or RX) positive pin
name of a TX-only (or RX-only) channel, instead of the corresponding transceiver Avalon Memory-
Mapped interface instance name. Assigning this option to two nodes directs the Fitter to view the
specified nodes as single group. The Fitter does not automatically merge the transceiver Avalon Memory-
Mapped interfaces; by default a CDR PLL, RX-only channel, and a TX-only channel map to three
different transceiver channels. If the Avalon Memory-Mapped interfaces of the transceiver channels can
be merged into one Avalon Memory-Mapped interface, the Fitter merges and places them in the same
transceiver channel. If the Fitter cannot merge the transceiver channels, your compilation will result in an
error.
