PROGRAMMABLE_POWER_TECHNOLOGY_SETTING
Controls how the fitter configures tiles to operate in high-speed mode or low-power mode. Automatic
specifies that the fitter should try to minimize power without sacrificing timing performance. Minimize
Power Only specifies that the fitter should set the maximum number of tiles to operate in low-power
mode. Force All Used Tiles to High Speed specifies that the fitter should set all used tiles to operate in
high-speed mode. Force All Tiles with Failing Timing Paths to High Speed specifies that the fitter should
ensure that all paths that are failing timing are set to high-speed mode. For designs that meet timing, the
behavior of this setting should be similar to the Automatic setting. For designs that fail timing, all paths
with negative slack will be put in high-speed mode. Note that this will likely not increase the speed of the
design, and it may increase static power consumption, but it may assist in determining which logic paths
need to be re-designed in order to close timing.
