  Global clock signals are low skew signals which save macrocells and routing resources when taken advantage of. Use your clocks like normal in your design. Note these cannot be gated clocks. Next using the Constraint Editor connect them to the global ...

  In an LatticeECP3 family of devices, only 7 out of 8 SECONDARY clocks are available. One of the SECONDARY clocks does not go to the clock input of registers in the fabric. It only goes to clock enable or set/reset pins. So, the SECONDARY clocks are ...
