2.1.4.1.4. LAB Clock Gate
The Stratix® 10 LAB register has built-in clock gating functionality. The register clock enable mechanism is a hardened data feedback, as shown in the Clock Gating and Clock Divider in Stratix® 10 Clock Network diagram. The LAB clock gate offers no associated power savings because this is a purely functional clock enable.
The analysis and synthesis phases of the Quartus® Prime software infer a LAB clock gate from a behavioral description of clock gating in the register transfer level (RTL). If a physical clock gate is desired, you must instantiate it explicitly.
