18.104.22.168. LAB Clock Power
To reduce LAB-wide clock power consumption without disabling the entire clock tree, use the LAB-wide clock enable to gate the LAB-wide clock. The Intel® Quartus® Prime software automatically promotes register-level clock enable signals to the LAB-level. A shared gated clock controls all registers within an LAB that share a common clock and clock enable. To take advantage of these clock enables, use a clock enable construct in the relevant HDL code for the registered logic.
