4.4.1. Fitter Effort Setting

For designs with very tight timing requirements, both Auto Fit and Standard Fit use the maximum effort during optimization. Intel recommends using Auto Fit for reducing compilation time.

The highest Fitter effort setting, Standard Fit, requires the most runtime, but does not always yield a better result than using the default Auto Fit. If you are certain that your design has only easy-to-meet timing constraints, you can select Fast Fit for an even greater runtime savings.
