1.10.256. PLACEMENT_EFFORT_MULTIPLIER

Controls how much time the fitter spends in placement. The default value is 1.0 and legal values must be greater than 0. Specifying a floating-point number allows you to control the placement effort. A higher value increases CPU time but may improve placement quality. For example, a value of '4' will increase fitting time by approximately 2 to 4 times but may increase quality.
