Creating the Example Design Nios II Hardware Development Tutorial
Assign FPGA pins
If you are targeting a custom board, you must assign a specific target
device and then assign FPGA pin locations to match the pinouts of your
board.
1 Skip ahead to section “Compile the Quartus II Project and Verify
Timing” on page 1–32, if you are targeting a Nios development
board. The provided Quartus II project files already contain
appropriate assignments for Nios development boards.
You must know the pin layout for the custom board to complete this
section. You also must know other requirements for using the board,
which are beyond the scope of this document. Refer to the documentation
for your board.
To assign the device, perform the following steps:
1. On the Assignments menu, click Device. The Settings dialog box
appears.
2. In the Family list, select the FPGA family that matches your board.
3. Click No if a dialog box asks, "Device family selection has changed.
Do you want to remove all location assignments?"
4. Under Tar get Devic e select Specific device selected in 'Available
devices' list.
5. Under Available devices select the exact device that matches your
board.
6. Click No if a dialog box asks, "Altera recommends removing all
location assignments when changing the device. Do you want to
remove all location assignments?"
7. Click OK to accept the device assignment.
