Birthday Circuit design Design a combinational logic circuit that displays your birth day on a seven segment display using the format: MM-DD-YY The 7-segment display may be a common anode or a common cathode. Date of Birth X Y Z 7-Segment Display Driver Logic Enzo Paterno a b c d e f g 1 Birthday Circuit design Example: Birth date is July 23, 1995 X Date of Birth Y 7-Segment Display Z Driver Logic a b c d e f g using a PLD Enzo Paterno X Y Z 0 0 0 0 0 1 0 1 0 0 1 1 1 0 0 1 0 1 1 1 0 1 1 1 2 Part 1  Generate the truth table for this design  Generate all the necessary Boolean equations (i.e. SOPs)  Simplify the Boolean equations  Usage of Karnaugh Minimizer SW is allowed  Simulate your circuit using Circuit Maker Demonstrate simulation to your instructor Student Name: ____________________ BIRTHDAY: _______________________ Enzo Paterno 3 Part 2  Write a WINCUPL program for your birthday  Build the circuit using a PLD (22V10 or 16V8) Digital Module 3 7 PLD 7-seg display Demonstrate PLD circuit to your instructor Student Name: ____________________ BIRTHDAY: _______________________ Enzo Paterno 4 Part 2 Enzo Paterno 5 Part 2 Common Anode: M72 Enzo Paterno 6 Part 2 Common Cathode: M74 Enzo Paterno 7 Part 3  Build the circuit using a 4-bit counter whose clock is provided by a Function Generator (FG) Function generator clock 4-bit counter 3 7 PLD 7-seg display Demonstrate clock/FG circuit to your instructor Student Name: ____________________ BIRTHDAY: _______________________ Enzo Paterno 8 Part 3 Enzo Paterno 74LS163 Timing Diagram 9 Part 4 Modify your birthday circuit such that:  Use the 555 timer chip to generate the clock for the 74LS163 counter. The RC circuit is designed to display each digit with a 1 second delay. As well use a potentiometer so to adjust the frequency of the display  Use a 9 volt battery along with the 7805 voltage regulator to provide the 5 volts supply.
