Clock Routing
The clock routing structure in LatticeXP devices consists of four Primary Clock lines and a Secondary Clock net-
work per quadrant. The primary clocks are generated from MUXs located in each quadrant. Figure 2-7 shows this
clock routing. The four secondary clocks are generated from MUXs located in each quadrant as shown in Figure 2-
8. Each slice derives its clock from the primary clock lines, secondary clock lines and routing as shown in Figure 2-
