Comma alignment is set to align on even boundaries only. This is a mistake because when alignment occurs, it causes disparity errors which can eventually bring down the link.
Work around this issue by making the following changes:
In the gtx_wrapper_gtx.v or gtx_wrapper_gtx.vhd files:
.ALIGN_COMMA_WORD (1)
on each MGT instance.
In the gtx_wrapper.xco or gtx_wrapper_vhd.xco:
CSET comma_alignment=Any_Byte_Boundary
