Hi,


As mentioned in this KDB https://www.intel.com/content/www/us/en/support/programmable/articles/000076600.html

You can prevent glitches during clock switchover by using the ena port.


The ensure glitch free clock switchover option is not available in any of the Clock Control IP for Stratix 10 at the moment unfortunately, so you'll have to use clock enable : https://www.intel.com/content/www/us/en/docs/programmable/683195/20-3/ip-core-parameters-29948.html
