FITTER_AUTO_EFFORT_DESIRED_SLACK_MARGIN
FITTER_AUTO_EFFORT_DESIRED_SLACK_MARGIN
Type
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 reduces optimization effort to reduce
compilation time. Otherwise, its behavior is the same as it is with the Standard Fit
setting for the FITTER_EFFORT option.
