The GTM_DUAL primive contains one LCPLL and two GTM channels. Contrary to other
UltraScale+ device transceivers such as the GTH and GTY transceivers, the GTM transceiver
does not contain channel/common primives. All channel ports and aributes are within the
GTM_DUAL primive. The following gure illustrates the topology of a GTM channel.
