IOP_SWITCH clock

In UG1085, Zynq UltraScale+ Device TRM, page 1044, the IOP_SWITCH_CLK is referenced as the clock source for the MDC signal.  In Vivado (v2018.1), an IOU_SWITCH clock is setup in "Clock Configuration" but there is no IOP_SWITCH_CLK.  Also, in UG1085, the IOU_SWITCH clock is also referenced in two places.  I suspect these are referring to the same clock.  Please confirm these are the same clock or let me know how to setup the IOP_SWITCH clock.

Hi @cmuhlbauer,

 

GEM clock source is IOPLL in general when configured in PS.

IOPLL in LPD are interconnect and switch clock source for IOPLL.

 

Yes, it is IOU_SWITCH clock.
