Figure 2-12. Secondary Clock Selection
Slice Clock Selection
Figure 2-13 shows the clock selections and Figure 2-14 shows the control selections for Slice0 through Slice2. All
the primary clocks and the four secondary clocks are routed to this clock selection mux. Other signals, via routing,
can be used as clock inputs to the slices. Slice controls are generated from the secondary clocks 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.
