  1. For target devices in -1L, -1M, and -2L grades, certain link configurations and placements can be challenging for timing closure, in addition to generally increased challenge for high performance DMA / Bridge soft IP solutions. The IP customization GUI, by default, limits access to those link configurations even though they appear in this table. For more information, see Answer Record 000035682 for general guidance on selecting link configurations and placements for easier timing closure, and for specific guidance on accessing link configurations which are access limited by default by the IP customization GUI. AMD advises you to review this answer record at the start of project planning and prior to the start of board schematic capture.
