To assign the FPGA pin locations, perform the following steps:
1. On the Assignments menu, click Pins. The Quartus II Pin Planner
appears. The Quartus II project has many ready-made assignments
appropriate for a Nios development board, which you must
reassign to suit your board.
2. In the Node Name column, locate PLD_CLOCKINPUT[1]. You
might need to expand the PLD_CLOCKINPUT[1..1] category to
make PLD_CLOCKINPUT[1] visable.
3. In the PLD_CLOCKINPUT[1] row, double-click in the Location
cell. A list of available pin locations appears.
4. Select the appropriate FPGA pin that connects to the oscillator on
the board (see Figure 1–17).
