Error Message 12006 with Quartus Prime Standard Edition 23.1

The engineering team does not recommend reverting the SFL logic, as doing so may lead to unnecessary pulses or glitches, as mentioned in the following KDB article: https://www.intel.com/content/www/us/en/support/programmable/articles/000088178.html.

Users will need to add the altclkctrl module to their design.

Or

Recommend those who are using SFL IP to upgrade from older versions.
