1.11.46. FITTER_AUTO_EFFORT_DESIRED_SLACK_MARGIN

Specifies the amount of worst-case slack margin the fitter should try to maintain when the Fitter Effort option is set to 'Auto Fit'. If the design is likely to have at least this much slack on every path, the fitter will reduce optimization effort to reduce compilation time. Otherwise, its behavior will be the same as it is with the 'Standard Fit' Fitter Effort setting.
