1   Determine the device core fabric speed grade and transceiver speed grade that you require.
2   Determine the power grade and be aware that low power device codes are available.

The device speed grade affects the device timing performance and timing closure, as well as power utilization. One way to determine which speed grade your design requires is to consider the supported clock rates for specific I/O interfaces.

The IP, Hard Memory NoC, and transceivers have performance specifications based on the device speed grade you choose. For more information about performance specifications based on the device speed grade, refer to the Intel Agilex® 7 M-Series Device Data Sheet.

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.
