  3. Click Finish to return to Qsys.On the System Contents tab, an instance of the fault_injection_0 appears in the system contents table.
  4. Connect clk_reset port of the clk_0 clock source to the reset port of the fault_injection_0.
  5. Connect intosc port of the fault_injection_0 to clock port of emr_unloader2_0.
  6. Connect intosc port of the fault_injection_0 to clock port of adv_seu_detection_0.
  7. Connect crcerror_pin port of emr_unloader2_0 to crcerror_pin port of fault_injection_0.
  8. Double click the error_injected, and error_scrubbed of the fault_injection_0 at Export column to export them for external access, leave the name default.
