The DE0-Nano System Builder is a Windows based software utility, designed to assist users in
creating a Quartus II project for the DE0-Nano board within minutes. The generated Quartus II
project files include:

Quartus II Project File (.qpf)

Quartus II Setting File (.qsf)

Top-Level Design File (.v)

Synopsys Design Constraints file (.sdc)

Pin Assignment Document (.htm)
By providing the above files, DE0-Nano System Builder helps to prevents occurrence of situations
that are prone to errors when users manually edit the top-level design file or place pin assignments.
The common mistakes that users encounter are the following:
1. Board damaged for wrong pin/bank voltage assignments.
2. Board malfunction caused by wrong device connections or missing pin counts for connected
ends.
3. Performance degeneration because of improper pin assignments.

This section will introduce the general design flow to build a project for the DE0-Nano board via
the DE0-Nano System Builder. The general design flow is illustrated in
Figure 5-1 .
To create a new system using the DE0-Nano System Builder, begin by launching the DE0-Nano
System Builder software. The software will then prompt you to specify the name of the project you
wish to create, as well as the components on the DE0-Nano board you wish to you. Once your
specification is complete, you can generate the system.
