25.1

In PR file management method 1, you specify unique entity and file name pairs for each persona in the project. For example:

  • Define the apple persona in the apple.sv file
  • Define the orange persona in the orange.sv file
  • Define the banana persona in the banana.sv file
Note: For successful compilation and PR operation, all personas must have the exact same port names and widths defined in each .sv file.

In the base PR revision RTL, you specify "apple" as the PR persona for both PR regions:

Figure 24. Setting the Base PR Persona to "apple"

When you set the base persona to [apple, apple] by setting u_fruit_0 and u_fruit_1 as the PR partition and regions, you can easily change the persona occupying the PR region using the Entity Rebinding (ENTITY_REBINDING) option in the Design Partitions Window, or by editing the .qsf directly, as the following examples show:

To specify the orange persona for a PR implementation (impl) revision:

set_instance_assignment -name ENTITY_REBINDING orange -to u_fruit_0
set_instance_assignment -name ENTITY_REBINDING orange -to u_fruit_1

To specify the banana persona for another PR implementation (impl) revision:

set_instance_assignment -name ENTITY_REBINDING banana -to u_fruit_0
set_instance_assignment -name ENTITY_REBINDING banana -to u_fruit_1

To specify different personas for each PR region in an implementation revision:

set_instance_assignment -name ENTITY_REBINDING orange -to u_fruit_0
set_instance_assignment -name ENTITY_REBINDING banana -to u_fruit_1

For each implementation revision, you must ensure that you include the corresponding source file in the project (Project > Add/Remove Files in Project).
