1.5.4. Step 4: Optimize the Reserved Core Partitions

Next, you optimize the RTL of the blinking_led_8s and blinking_led_16s reserved core partitions.
  1. Update the RTL for blinking_led_8s and blinking_led_16s to correct the timing violations and asynchronous reset.
    Note: To accelerate this step, you can simply copy the blinking_led_8s.sv and blinking_led_16s.sv from the golden_rtl directory, and paste the files into the tutorial_impl directory, overwriting the existing files.
  2. Click Compile Design on the Compilation Dashboard. The Compilation Dashboard displays the time spent in each module of the Compiler and the total compilation time.
