Use this option to control device power consumption. Select Low or Standard to set the default power mode for the macrocells used to implement the design. Select Timing Driven to automatically reduce power on paths covered by timing specifications that can meet speed requirements while operating in low power. The default is Standard, which results in highest speed.
Note: Any explicit power control (PWR_MODE) properties in the design or constraints file take precedence over this Macrocell Power Setting.
