"WebThe Verilog clock divider is simulated and verified on FPGA. The frequency of the output clock_out is equal to the frequency of the input clock_out divided by the value of the DIVISOR parameter in the Verilog code. F (clock_out) = F (clock_in)/DIVISOR To change the clock frequency of the clock_out, just modify the DIVISOR parameter. " - Clock dividing circuit in synthesis
