New ContributorNiosii PLL
Hello I'm a beginner in programming FPGA devices. I have to create several frequencies multiplier using PLL from an one Hertz input signal. With a nios processor I have to be able to make a program ...

Regular ContributorWell it will be the case that you can't feed your 1Hz input signal into the hardware PLL on the FPGA and use it to multiply your frequency. So you have to find a different way to do it.
But I might suggest it will rely on building a digital PLL state machine, oversampling your input 1Hz signal as the input, and generating an output signal that is 2X, 3X, 4X, etc of the input, based on user selection.
ElyoussGot it thank you very much for your answer !
