2.1.1. Set a High-Speed Target

For silicon efficiency, set your speed target as high as possible. The Intel® Hyperflex™ architecture LUT is essentially a tiny ROM capable of a billion lookups per second. Operating this LUT at 156 MHz uses only 15% of the capacity.

While setting a high-speed target, you must also maintain a comfortable guard band between the speed at which you can close timing, and the actual system speed required. Addressing the timing closure initially with margin is much easier.
