Updating the Top-Level Design

To update the top.sv file with the PR_IP instance:
  1. To add the pr_ip instance to the top-level design, uncomment the following code block in top.sv file: 
    pr_ip u_pr_ip
    (
        .clk           (clock),
        .nreset        (1'b1),
        .freeze        (freeze),
        .pr_start      (1'b0),            // ignored for JTAG
        .status        (pr_ip_status),
        .data          (16'b0),
        .data_valid    (1'b0),
        .data_ready    ()
    );
  2. To force the output ports to logic 1 during reconfiguration, use the freeze control signal output from PR_IP. Uncomment the following lines of code:
    assign led_two_on_w    = freeze ? 1'b1 : pr_led_two_on;
assign led_three_on_w  = freeze ? 1'b1 : pr_led_three_on;
  3. To assign an instance of the default persona (blinking_led), update the top.sv file with the following block of code:
    blinking_led u_blinking_led
    (
        .led_two_on	(pr_led_two_on),
        .led_three_on (pr_led_three_on),
        .clock	(clock),
        .counter (count_d)
    );
