Step 4: Defining Personas
This reference design defines three separate personas for the single PR partition. To define and include the personas in your project:
- Create three SystemVerilog files, blinking_led.sv, blinking_led_slow.sv, and blinking_led_empty.sv in your working directory for the three personas.
Table 2. Reference Design Personas File Name Description Code blinking_led.sv Default persona with same design as the flat implementation `timescale 1 ps / 1 ps `default_nettype none module blinking_led ( // clock input wire clock, input wire [31:0] counter, // Control signals for the LEDs output wire led_two_on, output wire led_three_on ); localparam COUNTER_TAP = 23; reg led_two_on_r; reg led_three_on_r; assign led_two_on = led_two_on_r; assign led_three_on = led_three_on_r; always_ff @(posedge clock) begin led_two_on_r <= counter[COUNTER_TAP]; led_three_on_r <= counter[COUNTER_TAP]; end endmoduleblinking_led_slow.sv LEDs blink slower `timescale 1 ps / 1 ps `default_nettype none module blinking_led_slow ( // clock input wire clock, input wire [31:0] counter, // Control signals for the LEDs output wire led_two_on, output wire led_three_on ); localparam COUNTER_TAP = 27; reg led_two_on_r; reg led_three_on_r; assign led_two_on = led_two_on_r; assign led_three_on = led_three_on_r; always_ff @(posedge clock) begin led_two_on_r <= counter[COUNTER_TAP]; led_three_on_r <= counter[COUNTER_TAP]; end endmoduleblinking_led_empty.sv LEDs stay ON `timescale 1 ps / 1 ps `default_nettype none module blinking_led_empty( // clock input wire clock, input wire [31:0] counter, // Control signals for the LEDs output wire led_two_on, output wire led_three_on ); // LED is active low assign led_two_on = 1'b0; assign led_three_on = 1'b0; endmodule
Note:
- blinking_led.sv is already available as part of the files you copy from the flat/ sub-directory. You can simply reuse this file.
- 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.
