Both the OSERDES modules must be adjacent master and slave pairs.
Set the SERDES_MODE attribute for the master OSERDES to MASTER and the slave
OSERDES to SLAVE (see
The user must connect the SHIFTIN ports of the MASTER to the SHIFTOUT ports of
the SLAVE.
The SLAVE only uses the ports D3 to D6 as an input.
Master and Slave have the same DATA_WIDTH attribute value.
