Webhow to use dynamic phase shift I use vivado 2014.4,Kintex 7 325T,and I want to dynamic change the clock output phase,and I assert the PSEN and PSINCDEC,after some clock periods,the mmcm assert the PSDONE,but I compare the clock_in with clock_out,the phase does not change any.do someone know why? and what should I do WebConfigure the Clock Wizard to accept a differential clock. This is just a check box. You will need to select either a MMCM or PLL. For most designs, choose the MMCM. This will let you create different frequency and phase clocks from teh input clock. The Wizard will also instantiate all of the necessary clock buffers.
WebHow to use the "locked" port of the clock wizard? I'm a newcomer of FPGA design, and I want to use the clock wizard core. I find the core has a output port: " locked" which indicates wether MMCM/PLL has been locked or not. I wonder how to use this port? what if the clock is fed into sequential logic before it is locked? WebEach CMT can output up to seven independant clock signals. They can be faster or slower than in the input clock, and they can have precise phase control, good stability, and low jitter. Vivado’s Clocking Wizard is an easy way to …

Further, if you have to go that road, you can get the phase noise down by outputting the clock on a pin through the OSERDESE2 structure and then bringing it back in through a PLL--however, that'll bring you back to stuck within the limits of what a PLL or MMCM can provide.
