It is a common practice to define the location of transceiver Quads early in the design process to ensure correct usage of clock resources and to facilitate signal integrity analysis during board design. The implementation flow facilitates this practice through the use of location constraints in the XDC file.

The position of each GTM transceiver Quad primitive is specified by an XY coordinate system that describes the column number and the relative position within that column.

Use the I/O planner in the Vivado tools to set the transceiver locations. Alternatively, user designs can manually add placement locations for the GTM transceiver. Care must be taken to ensure that all of the parameters needed to configure the transceiver are correctly entered. For more information on GTM transceiver placement, see Versal ACAP Transceivers Wizard LogiCORE IP Product Guide (PG331).
