Each device architecture has some dedicated resources for clocking. Understanding the clocking resources for your device architecture can allow you to plan your clocking to best utilize those resources. Most designs might not need you to be aware of these details. However, if you can control the placement and have a good idea of the fanout on each of the clocking domains, you can explore alternatives based on the following clocking details. If you decide to exploit any of these clocking resources, you need to explicitly instantiate the corresponding clocking element.
