PROGRAMMABLE_POWER_MAXIMUM_HIGH_SPEED_FRACTION_OF_USED_LAB_TILES

Sets an upper limit on the fraction of the LAB tiles used by your design that can be high-speed. Legal values must be between 0.0 and 1.0. The default value is 1.0. A value of 1.0 means that there is no restriction on the number of high-speed tiles, and the fitter will use the minimum number needed to meet the timing requirements of your design. Specifying a value lower than 1.0 might degrade timing quality, because some timing critical resources might be forced into low-power mode.
