Nios II Hardware Development Tutorial Creating the Example Design
1 It is a good habit to give memorable names to hardware
components. Nios II programs use these symbolic names to
access the component hardware. Therefore, your choice of
component names can make Nios II programs easier to read and
understand.

II Handbook Volume 5: Embedded Peripherals.
Add the System ID Peripheral
The system ID peripheral safeguards against accidentally downloading
software compiled for a different Nios II system. If the system includes
the system ID peripheral, the Nios II IDE prevents you from
downloading programs compiled for a different system.
Perform the following steps to add the system ID peripheral:
1. In the list of available components, expand Peripherals, expand
Debug and Performance, and then click System ID Peripheral.
2. Click Add.... The System ID Peripheral MegaWizard interface
appears. The system ID peripheral has no user-configurable options
(see Figure 1–11).

3. Click Finish. You return to the SOPC Builder System Contents tab,
and an instance of the system ID peripheral named sysid now
appears in the table of available components.

chapter of the Quartus II Handbook Volume 5: Embedded Peripherals.
