FITTER_EFFORT
Controls the fitter's trade-off between performance and compilation speed. Auto Fit adjusts the fitter optimization effort to minimize compilation time, while still achieving the design timing requirements. The Auto Fit Effort Desired Slack Margin option can be used to request that Auto Fit apply sufficient optimization effort to achieve additional timing margin. Standard Fit will use maximum effort regardless of the design's requirements, leading to higher compilation time and more margin on easier designs. For difficult designs, Auto Fit and Standard Fit will both use maximum effort. Fast Fit will decrease optimization effort to reduce compilation time, which may degrade design performance.
