XPS provides a central clocking mechanism through use of the Clock Generator IP. The clock generator recognizes the clock requirements for all IP and generates the desired MMCM/PLL configurations as part of the IP.
In the IP integrator, use the clocking_wizard for clock
configuration.
Important: You must enter the desired frequency as
part of the clocking wizard IP. The properties of the generated clocks (such as
frequency and phase) are propagated from the Clocking IP to the individual IP
through use of the parameter propagation methods implemented by the IP.
