Basic I/O under the DE2-70 FPGA Board Objectives Knowing the Basics of VHDL programming Language Being familiar with Quartus Development Software Downloading a program to a hardware application board Using input switches: Toggle and Push Buttons Using output LEDs Technical Resources DE2-70 User Manual Equipment needed DE2-70 Application Board Software Packages Altera Quartus II Software Requirements Implement the following under the DE2-70 Board: a. Two-bit Binary Adder Design a 2 bits Binary Adder. The inputs are push buttons. The Adder has three outputs; they are display on the LEDs of the application board. Use Structural VHDL. b. Recognizer Design a 2 bits Binary Adder. If the result of addition is greater than two, the variable detector is set to TRUE. The inputs are entered using DIP switches. The result and detector outputs are displayed on the LEDs of the application board. Use Behavioral VHDL
