Speed Grade

The device speed grade affects the device timing performance and timing closure, as well as power utilization. There are two speed grades available: 5 (fastest) and 6. One way to determine which speed grade your design requires is to consider the supported clock rates for specific I/O interfaces.

You can use the fastest speed grade during prototyping to reduce compilation time (because less time is spent optimizing the design to meet timing requirements), and then move to a slower speed grade for production to reduce cost if the design meets its timing requirements.
