1.2.146. SYNTH_GATED_CLOCK_CONVERSION
Automatically converts gated clocks in the design to use clock enable pins if clock enable pins are not used in the original design. Clock gating logic can contain AND, OR, MUX, and NOT gates. Turning on this option may increase memory use and overall run time. You must use the TimeQuest Timing Analyzer for timing analysis, and you must define all base clocks in Synopsys Design Constraints (SDC) format.
