Lattice Semiconductor
this special vertical routing channel and the eight secondary clock regions for the ECP2-50. LatticeECP2 devices
have four secondary clocks (SC0 to SC3) which are distrubed to every region.
The secondary clock muxes are located in the center of the device. Figure 2-16 shows the mux structure of the
secondary clock routing. Secondary clocks SC0 to SC3 are used for clock and control and SC4 to SC7 are used for
high fan-out signals.
