Step 5: Defining Personas

This reference design defines five separate personas for the parent and child PR partitions. To define and include the personas in your project:

  1. Create four SystemVerilog files, blinking_led_child.sv, blinking_led_child_slow.sv, blinking_led_child_empty.sv, and blinking_led_slow.sv in your working directory for the five personas.
    Note: If you create the SystemVerilog files from the Intel® Quartus® Prime Text Editor, disable the Add file to current project option when saving the files.
