The I/O Planning view includes the I/O Ports and Package Pins tabs. AMD recommends I/O planning high-speed interfaces in the following order to achieve the maximum utilization of available XP5IO logic resources:
  1. Integrated DDRMC through NoC
  2. Soft memory controllers
  3. XP5IO wizard
  4. I/O logic

This tool only allows for nibble and bank level granularity. If more granularity is required, use the classic pin planning tools. If the XP5IO Wizard IP exists in the design, the banners of both tabs contain a message and a button to launch the Advanced I/O Planner. The Advanced I/O Planner understands any interface in the XP5IO I/O block. If there is a hard memory controller, this also appears in the Advanced I/O Planner. The placement of these interfaces is arranged as optimal as possible based on a centralized hardware rule based engine. There is a priority to this list, such as hard memory controller, soft memory controller.
