про одну из опций - Optimize fast-corner timing (выделение мое):

******************************************
Directs the Fitter to consider fast-corner timing delays as well as slow-corner timing delays during optimization to meet timing requirements at both corners. By default, this option is off, and the Fitter optimizes designs considering only slow-corner delays, from the slow-corner timing model (slowest manufactured device for a given speed grade, operating in high-temperature and low-voltage conditions). When this option is on, the Fitter optimizes designs considering fast-corner delays, in addition to slow-corner delays, from the fast-corner timing model (fastest manufactured device, operating in low-temperature and high-voltage conditions).

This option is available for Cyclone, Cyclone II, MAX II, Stratix, Stratix II, and Stratix GX devices only.
