To open the Quartus II project, perform the following steps:
1. Start the Quartus II software.
On Windows computers, click Start , point to Programs , Altera , Quartus II
<version> , and then click Quartus II <version> . On Linux computers, type
quartus
at a shell command prompt, assuming the Quartus II program directory is in the
search path.
2. Click Open Existing Project on the splash screen, or, on the File menu, click Open
Project . The Open Project dialog box appears.
3. Browse to the <design files directory> .
4. Select the file nios2_quartus2_project.qpf and click Open . The project opens.
5. To display the Block Diagram File (
.bdf
)
nios2_quartus2_project.bdf
( Figure 1–3 ),
perform the following steps:
a. On the File menu, click Open . The Open dialog box appears.
b. Browse to the <design files directory> .
c. Select nios2_quartus2_project.bdf and click Open .
Figure 1–3 shows the nios2_quartus2_project.bdf file.
The .bdf contains an input pin for the clock input and eight output pins to drive LEDs
on the board. Next, you create a new Qsys system, which you ultimately connect to
these pins.
Create a New Qsys System
You use Qsys to generate the Nios II processor system, adding the desired
components, and configuring how they connect together. To create a new Qsys
system, click
Qsys on the Tools menu in the Quartus II software. Qsys starts and
displays the System Contents tab.
