This paper describes the use of examples prescaler to use VHDL design on FPGA/CPLD, including even frequency, non-50 duty cycle and 50 duty cycle odd frequency, half-integer (N+0.5) Divide, fractional, fractional and integral crossover frequency. All can be achieved through Synplify Pro FPGA synthesizer manufacturer or integrated to form a circuit that can be used and verified in ModelSim.
