Guidelines for Expanding the Serial-to-Parallel Converter Bit Width
Verilog Instantiation Template to use Width Expansion Feature
1.

5.
6.
The following Verilog code uses the width expansion feature in DDR mode with a
deserialization factor of 1:10.
Both ISERDES modules must be adjacent master and slave pairs.
Both ISERDES modules must be in NETWORKING mode (width expansion is not
available in MEMORY mode).
Set the SERDES_MODE attribute for the master ISERDES to MASTER and the slave
ISERDES to SLAVE (see
The user must connect the SHIFTIN ports of the SLAVE to the SHIFTOUT ports of the
MASTER.
The SLAVE only uses the ports Q3 to Q6 as outputs.
DATA_WIDTH for Master and Slave must match.
