Adding New Features to Nonsafety IP

To demonstrate adding a new feature to a nonsafety IP, add a timer function to the Qsys system. The timer function connects up to Nios processor in the nonsafety IP partition and to clocks created from the PLL in the safety IP partition.

  1. Open Qsys.
  2. In the System Contents tab, scroll to the bottom of the component list and turn on timer_0 component (select the checkbox in the Use column).
  3. Regenerate the Qsys system.
