Nios II Hardware Development Tutorial Creating the Example Design

Figure 1–16 shows an example of the Settings dialog box assigning a

Cyclone device.

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).
