I need to bring CPLLREFCLKSEL to the top of the hierarchy to be able to make speed changes

描述

For 7 Series transceivers, users sometimes need to bring the CPLLREFCLKSEL port to the top of the hierarchy to enable speed changes.

In the current wizard this is not allowed and users need to unmanage the core to be able to make this change.

解决方案

There is a way to bring this port to the top of the hierarchy.

  1. Open your normal wizard template and note the selections you have made for your design or protocol.
    Alternatively take a screenshot of each page of the GT wizard.
  2. Open the wizard and choose the display port template.
    Using this template will bring the CPLLREFCLKSEL port to the top level.
  3. Change the settings to the settings that you have noted in step 1 so that the wizard will deliver your protocol.

Now, when you generate the example design, the CPLLREFCLKSEL port will be brought to the top of the hierarchy.
