Preliminary

3. Building the SOPC System

In this chapter you add standard and custom components to the system, make

connections where required, assign the clocks, set arbitration priorities, and generate

the system.

The tutorial SOPC Builder system contains 24 components. You start with a partially

completed SOPC Builder system, to which you add a Nios II embedded processor, a

DDR SDRAM high-performance controller, an Avalon-MM clock-crossing bridge

peripheral, and a scatter-gather DMA controller. A table describes the function of each

of the components.

After you add the components to the system, you must perform some additional steps

to make the components work together. All of the necessary steps are included in this

chapter.

If you wish to skip the steps to create the FPGA configuration file (.sof), you can skip

this chapter and use the Quartus II Archive file (.qar) available in your working

directory.

Run the Quartus II Software and SOPC Builder

To run SOPC Builder, perform the following steps:

1. To run the Quartus II software, on your Windows system, click

Start > All Programs > Altera > Quartus II <version>.

2. On the File menu, click Open Project.

3. Browse to your working directory and highlight neek_hw_lab.qpf.

4. Click Open.

The Quartus II project for the tutorial opens. It is missing the Nios II processor and

some of the other components that implement the digital picture viewer. In the

following steps, you add these components.

5. On the Tools menu, click SOPC Builder.

SOPC Builder opens with a system that is missing a few key components.

In the following section, you add the missing components to the system.

Specify the SOPC Builder System Components

The partially completed SOPC Builder system provided in your Quartus II project

contains the LCD controller, video pipeline, and various other peripherals. This

section teaches you how to specify the missing components to add to your SOPC

Builder system. You add four critical components to your SOPC Builder system.
