Clock dividing circuit in synthesis
WebHello, I wanted to understand what is the main difference between generating clock from PLL/MMCM and using clock divider logic in RTL especially when the clock to be divided by 2, 4,8,16 times etc I understand to generate a random frequency outputs, the PLL/MMCM are very useful.
