Figure 2-16. Per Region Secondary Clock Selection
Slice Clock Selection
Figure 2-17 shows the clock selections and Figure 2-18 shows the control selections for Slice0 through Slice2. All
the primary clocks and seven secondary clocks are routed to this clock selection mux. Other signals can be used
as a clock input to the slices via routing. Slice controls are generated from the secondary clocks/controls or other
signals connected via routing.
If none of the signals are selected for both clock and control then the default value of the mux output is 1. Slice 3
does not have any registers; therefore it does not have the clock or control muxes.
