Using the altera altclkctrl mega function will take up a lot of DSP resources, do you have a solution to set the mega core to not take up DSP resources. Otherwise the resources will not be enough for our design. please help~

ALTCLKCTRL doesn't use any DSP resources. It uses the clock control blocks for putting clocks and high fanout control signals on the global clock resources. It doesn't even have anything to do with DSP. Where are you seeing this issue?
