3.6.5.5.6. 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 SBT for Eclipse can prevent you from downloading programs compiled for a different system. To add system ID peripheral, perform the following steps:

  1. On the IP Catalog tab, expand Basic Functions, expand Simulations; Debug and Verifications and then click System ID Peripheral.
  2. Click Add.
    The System ID Peripheral parameter editor appears and do not change the default setting.
  3. Click Finish and return to the Platform Designer System Contents tab.
    The system ID peripheral instance appears in the system contents table.
  4. In the Name column, right-click the system ID peripheral and click Rename.
  5. Type sysid and press Enter.
  6. Connect the clk port of the clk_0 clock source to the clk port of the system ID peripheral.
  7. Connect the clk_reset port of the clk_0 clock source to the reset port of the system ID peripheral.
  8. Connect the data_master port of the Nios® II processor to the control_slave port of the system ID peripheral.
