Difficulty using clocks on F-Series Development Kit

I'm not familiar with the IP you mention. Do you mean a clock control block (altclkctrl)? These are used for selecting clock sources, global clock enables, and connections to the global clock routing channels of the device (the global I believe you are asking about).

Always a good idea to go through the user guide for your device: https://www.intel.com/content/www/us/en/docs/programmable/683761/24-1/fpga-clocking-and-pll-overview.html
