Clocking Wizard helps create the clocking circuit for the required output clock frequency, phase, and duty cycle using a mixed-mode clock manager (MMCM)(E2/E3/E4) or phase-locked loop (PLL)(E2/E3/E4) primitive. It also helps verify the output generated clock frequency in simulation, providing a synthesizable example design which can be tested on the hardware. It also supports the Spread Spectrum feature, which is helpful in reducing electromagnetic interference. This Figure shows a block diagram of the Clocking Wizard.
