If the prototype system adequately meets design requirements using an Intel-
provided reference design, you can copy the reference design and use it without
modification in the final hardware platform. Otherwise, you can customize the Nios II
processor system until it meets cost or performance requirements.

1.3. Customizing Nios II Processor Designs

In practice, most FPGA designs implement some extra logic in addition to the
processor system. Intel FPGAs provide flexibility to add features and enhance
performance of the Nios II processor system. You can also eliminate unnecessary
processor features and peripherals to fit the design in a smaller, lower-cost device.
