Virtex-II Pro RocketIO - If a data width is specified for the GT_CUSTOM primitive, must I still zero-pad data and byte-map control signals when using 1-byte and 2-byte paths?

Description

If a data width is specified for the GT_CUSTOM primitive, am I still responsible for zero-padding data and byte-mapping control signals when I use 1-byte and 2-byte paths?

Solution

Yes, the GT_CUSTOM primitive does not use these attributes to size the ports.
