VHDL design in Quartus II
Reference: In Class Demos and Power Point on D2L Chapter 05 Combinatorial VHDL
Reference: In Class Demos and Power Point on D2L Chapter 05 Combinatorial VHDL
REQUIRED:
• Determine the Boolean expression and truth table for each diagram.
• Create a VHDL design for the circuit and test using the cyc1000 dev board.
•
• PROCEDURE:
•
For the following circuit, write the Boolean expression for the output variable and produce a truth table. Create a VHDL design in Quartus for the circuit. Use onboard active high LED. Use the DIP switch you wired to the cyc1000 dev board to produce a high or low for each input. Verify the operation described by the Boolean expression and the truth table.
