In addition to these hardware features, the DE2-70 board has software support for standard I/O interfaces and a control panel facility for accessing various components. Also, software is provided for a number of demonstrations that illustrate the advanced capabilities of the DE2-70 board.

In order to use the DE2-70 board, the user has to be familiar with the Quartus II software. The necessary knowledge can be acquired by reading the tutorials Getting Started with Altera’s DE2-70 Board and Quartus II Introduction (which exists in three versions based on the design entry method used, namely Verilog, VHDL or schematic entry). These tutorials are provided in the directory DE2_70_tutorials on the DE2-70 System CD-ROMthat accompanies the DE2-70 board and can also be found on Altera’s DE2-70 web pages.

2.2 Block Diagram of the DE2-70 Board

Figure 2.2 gives the block diagram of the DE2-70 board. To provide maximum flexibility for the user, all connections are made through the Cyclone II FPGA device. Thus, the user can configure the FPGA to implement any system design.
