The Nios® II Ethernet Standard hardware design example provides a mix of peripherals and memories similar to a typical Nios II processor system. This design interfaces with each hardware component on the Altera® development board, such as SDRAM, LEDs, push buttons, and an Ethernet physical interface or media access control (PHY/MAC). You can use the Nios II Ethernet Standard design as a starting point for your own embedded system by adding or removing components to meet your custom requirements. This Qsys-based hierarchical design has a top-level system and two subsystems, namely: peripherals subsystem and Ethernet subsystem as shown in Figure 1.
This design is provided for the following Altera development kits:
- Nios II Embedded Evaluation Kit, Cyclone® III Edition
