After the project has been turned into a DFX project, RPs can be defined within the RTL source hierarchy. Appropriate instances within the design hierarchy are those that:

  • Are defined by RTL, IP, EDIF, or DCP sources
  • Do not pass parameter and generic values to that level of hierarchy from above. Parameters and generics can exist on the RP boundary but must be evaluated locally prior to partition creation.
  • Do not contain out-of-context (other than IP) modules in the underlying RTL
  • Do not have IP as the top level
  • Do not contain block diagram (.bd) sources
    1. Right-click on the desired module and select Create Partition Definition to begin the process of RP creation.

    2. In the dialog box that appears, give this partition definition a unique name. Also define a name for the first RM. This RM is created from the RTL sources currently residing in this level of hierarchy. More RM are added or created later in the flow.
      Important: Every instance of the selected module is turned into an RP. In order for one instance to be defined as reconfigurable and another instance to remain static, the two instances must be given unique module names.


    3. After clicking OK, this module displays differently in the Vivado IDE. Each instance of the module is shown in the Hierarchy view with a diamond, indicating that it is an RP. The design sources are moved to the Partition Definitions view to be managed separately. Repeat this step for all unique RPs required within the design.
