The DE2-115 System Builder is a Windows based software utility, designed to assist users to create
a Quartus II project for the DE2-115 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)
Synopsis Design Constraints file (.sdc)
Pin Assignment Document (.htm)
By providing the above files, DE2-115 System Builder 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.
