LatticeECP2/M Family Data Sheet
Primary Clock Routing
The clock routing structure in LatticeECP2/M devices consists of a network of eight primary clock lines (CLK0
through CLK7) per quadrant. The primary clocks of each quadrant are generated from muxes located in the center
of the device. All the clock sources are connected to these muxes. Figure 2-13 shows the clock routing for one
quadrant. Each quadrant mux is identical. If desired, any clock can be routed globally

Dynamic Clock Select (DCS)
The DCS is a smart multiplexer function available in the primary clock routing. It switches between two independent
input clock sources without any glitches or runt pulses. This is achieved regardless of when the select signal is tog-
gled. There are two DCS blocks per quadrant; in total, there are eight DCS blocks per device. The inputs to the
DCS block come from the center muxes. The output of the DCS is connected to primary clocks CLK6 and CLK7
(see Figure 2-13).
Figure 2-14 shows the timing waveforms of the default DCS operating mode. The DCS block can be programmed
to other modes. For more information about the DCS, please see the list of additional technical documentation at
the end of this data sheet.

Secondary Clock/Control Routing
Secondary clocks in the LatticeECP2 devices are region-based resources. The benefit of region-based resources
is the relatively low injection delay and skew within the region, as compared to primary clocks. EBR/DSP rows and
a special vertical routing channel bound the secondary clock regions. This special vertical routing channel aligns
with either the left edge of the center DSP block in the DSP row or the center of the DSP row. Figure 2-15 shows
