  1. In the Flow Navigator, right click Implementation and select Implementation Settings.
  2. In the Project Settings dialog box, select Implementation tab to make the following settings:
    • In the Opt Design settings, set the -directive option to Default.

      Block RAM optimization runs in the Default setting for Opt Design during Implementation. Block RAM optimization was disabled in the previous lab. It is now re-enabled when the design runs Power Optimization.

    • In the Power Opt Design settings, check the is_enabled box.

      This ensures Power Optimization runs after opt_design. Enabling the Power Opt Design option prior to place_design results in a complete power optimization to be performed. This option yields the best possible power saving from the Vivado tools.
